Top Ten Tips for Installing Vinyl Siding
CertainTeed provides quality vinyl siding and accessories that are backed by one of the industry???s best warranties. However, even the best products fall short of expectations if they are not installed properly. Following these ten
1.Install all siding and accessories over a smooth, flat surface. Always install siding over a rigid sheathing, and never install it over open studs.
2.Vinyl siding is not a watertight material. Install a
3.There are three recommended ways to cut vinyl siding:
For rip cuts, score the panel with a knife or vinyl blade and bend the panel back and forth. Use aviator snips or shears to fit panels around windows and doors. For cross cuts, use a circular saw with a plywood blade in the reverse position.
4.Always leave room for expansion and contraction into receiving channels like outside cornerposts, inside cornerposts, and
5.When installing horizontal vinyl siding panels 12' 6" in length or shorter, overlap the factory notches 1" to
6.Always nail in the center of the nail slots: 16" on center for siding; 8" to 12" for accessories.
7.DO NOT NAIL TIGHT! Always leave 1/8" to 1/16" between the nail head and the wall surface to allow for movement when the panel expands and contracts.
8.Hang vertical accessories from the top of the top nail slot. If the accessory is longer than 12', hang it from the top two nail slots.
9.Lap away from the highest traffic pattern, typically the front of the house. Keep laps at least 3' apart from course to course, and install three courses between laps above each other.
10.Finish the last piece of siding into utility trim or dual utility trim.

Important Fire Safety Information
Exterior vinyl building materials require little maintenance for many years. Nevertheless, common sense dictates that builders and suppliers of vinyl products store, handle and install vinyl materials in a manner that avoids damage to the product and/or the structure. Owners and installers should take a few simple steps to protect vinyl building materials from fire:
???To Home and Building Owners: Rigid vinyl siding is made from organic materials and will melt or burn when exposed to a significant source of flame or heat. Building owners, occupants and outside maintenance personnel should always take normal precautions to keep sources of fire, such as barbecues, and combustible materials, such as dry leaves, mulch and trash, away from vinyl siding.
???To the Building Trades, Specifiers, Professionals and
This manual shows the basic guidelines for installation. It is based on ASTM (American Society for Testing and Materials) D4756, the standard practice for installation of vinyl siding and soffit. Additionally, we recommend that local building codes be reviewed.

SECTION 6 ??? Preparing for Horizontal Siding
Preparing Wall Surfaces
Sheathings
In new construction, apply sheathing first, then nail accessories over it.
The application method you choose determines the width of the recess opening required. For example, use:
???1/2" opening when applying accessories over sheathing and installing siding with a panel projection of 1/2" or less.
???3/4" opening when applying accessories over sheathing and installing siding with a panel projection of 3/4" or less.
???
New construction
Make sure all studs are straight and true. Correct any bowed studs.
NOTE: Vinyl siding must be applied over a rigid sheathing that provides a smooth, flat surface or an underlayment (such as wood, wood composition, rigid foam or fiber sheathing) that is no more than 1" thick. Vinyl siding cannot be applied directly to studs. See the instructions on page 29 for installation over continuous insulation systems thicker than 1".
If you???re planning to use a conventional house wrap or building felt, apply according to the manufacturer???s recommendations. In all cases, however, install the products so they are secured firmly to the substrate so that they provide a smooth, even surface for the final siding installation. Make sure sheathing is fastened securely to studs.
Vinyl siding is an exterior cladding; it is not a complete weather resistant barrier. Before applying siding, make certain the substrate is watertight. In order to be protected from precipitation, the substrate may need to be properly flashed around areas such as windows, doors, other openings and corners so as to shed water to the exterior. See page 45 for proper flashing around windows. The siding alone is not meant to be a watertight barrier.
Vinyl siding cannot be installed on a radius wall.

Continuous foam insulation systems (SIPs)
Continuous foam insulation systems (e.g. rigid insulation, structural insulation products) thicker than 1" create a condition where CertainTeed vinyl siding and polymer shakes cannot be properly attached to the existing framing members, steel studs, or structural sheathing.

Home improvement projects
You can prepare your current siding surface to receive vinyl siding in one of three ways:
Strip off old siding and level the wall. If felt paper covers the wall, you have two alternatives: either strip it off completely or staple or nail it to create a smooth surface. If there is no solid sheathing under the old siding, you must apply it as described in the instructions for New Construction.
Apply rigid sheathing to existing siding to provide a smooth surface. Nail securely to old siding. Nail evenly to bridge low spots.
NOTE: Failure to establish a smooth, solid surface constitutes misapplication under the terms of the warranty.
Apply vertical furring to old siding to straighten noticeable surface unevenness. (See ???Tips for applying wood furring.???) Then apply rigid sheathing, following the instructions presented under New Construction.
NOTE: For information on installing siding over asbestos and for historic applications, see page 142.
Tips for applying wood furring
If you are working on an older home with noticeably uneven walls, you must correct this condition before proceeding. If not corrected during preparation, this uneven surface will produce a wavy appearance in siding applied over it.
For best results, space horizontal furring strips 12" on center. Do not exceed 16". To correct an uneven wall, use furring strips (and wood shims if necessary) to eliminate low spots.
NOTE: You must apply rigid sheathing over furring.

Although the fastening method for steel studs differs from wood construction, all other procedures still apply, including fastening in the center of the nail slot and not overtightening the fasteners.
Nailing, Stapling and Other
Fastening Methods
If you want to ensure a quality vinyl siding installation, focus your attention on nailing techniques. Unfortunately, a lot of installers don???t. They feel nailing is a routine task, something everyone knows how to do. But that???s not the case. At CertainTeed, we analyzed reported installation problems, and we found that more than half of them can be traced back to improper nailing. So if you want to save yourself lost time and frustration, carefully observe the following guidelines when installing accessories, siding panels, soffit, or porch ceilings.
Lock the panel and begin nailing at the center of the panel, working toward the ends. This helps maintain a level line.
With horizontal accessories and panels, position the nails in the center of the elongated nailing slots to allow for expansion and contraction. Never nail through the panel surface.
With vertical accessories and panels, position the first nail at the upper edge of the topmost nailing slot. This allows a panel to hang from the nail. Position the remaining nails in the center of the nailing slots. Allow for 1/3 of the total expansion at the top and 2/3 of the total expansion at the bottom.
33
CertainTeed Vinyl Siding Installation Guide
Up to 1/8"
Center staples in slots
NOTE: Do not nail too tightly. To permit expansion and contraction, panels should hang freely from nails. This allows the panels to move as the temperature changes. Drive the nails until there is between 1/8" to 1/16" of space between the nail head and the nailing flange.
Drive the nails straight in. Do not angle nails.
Per the ASTM specification for vinyl siding installation (D4756), proper nail penetration is at least 3/4". In most cases, that requires anchoring to studs.
Fastener spacing
Fasteners are typically spaced a maximum of 16" apart. In new construction, fasten to studs on 16" centers. Do not skip studs. Some vinyl siding may be used in 24" on center construction in areas without special
Other fastening techniques:
Manual nailing is the most common way of fastening vinyl siding to a wall. That???s because it offers greater control, making it easier to learn how to fasten panels securely, but not tightly. You also can use power screwdrivers or pneumatic staplers/ nailers to attach vinyl siding to a wall, but you must take the time to develop the proper skills. If you choose to use one of these
alternate techniques, follow all the recommendations above for nail positioning and spacing and the recommendations for substrate preparation on pages 28 to 32 for horizontal applications and page 80 for vertical, including Board & Batten. In addition, be sure to observe the following guidelines:
Power screwdrivers
Use noncorrosive,
Pneumatic staplers/nailers
Use
NOTE: Some power staplers/nailers use an attachment that helps position the fastener in the nail slot. If your unit does not have that feature, you must carefully position the fastener by sight.
34
CertainTeed Vinyl Siding Installation Guide
Fasteners must penetrate a nailable surface at least 3/4". Be sure to leave up to 1/16" between the fastener and the panel nailing flange. If you???re using a power stapler, drive the
staple perpendicular to the nailing slot with one leg of the staple centered in the slot and the other leg above the panel.
NOTE: Check with local building codes to verify fastener requirements for your area.
Nail Spacing and Product Expansion
and Contraction
It???s normal for vinyl building products to expand and contract with temperature changes. To ensure a successful siding installation, you must allow for this movement during application.
See the following charts for more information.

Installing Accessories
Snapping a chalk line
To ensure proper installation, you must establish a straight reference line to guide the positioning of the starter strip and the first course of siding.
If the house is reasonably level, find the lowest point of the old siding (or sheathing if working on new construction). Partially drive a nail at one corner, starter height minus 1/4" above the lowest corner. Attach chalk line. Go to other corner and pull the chalk line taut. Stretch the chalk line from this nail to the opposite corner
of the house. Make sure the line is level, using a line level or 4' (minimum) level. Snap chalk line and repeat the procedure around the entire house.
A water level, a long clear plastic tube 90% filled with water, is useful in marking level points around the house and on opposite sides of openings such as doors. Water will always seek a level state, ensuring the markings will always be at the same level.
NOTE: If after establishing a chalk line you find that your starter strip will be positioned below an easily nailed surface, you may have to apply a nailable base.
If you have added sheathing, you may want to bend trim coil to act as flashing and help prevent entry of insects. Bend the coil in a ???Z??? shape so the top edge of the coil is on the chalk line and the bottom edge extends down over the foundation. (See illustration.)
NOTE: The general guidelines for cutting and nailing vinyl panels and for allowing for expansion and contraction also apply to vinyl accessory items.
Installing the starter strip
Position the starter strip with the top edge on the chalk line and the ends
As you add starter strip sections, be sure to leave 1/4" space between them for expansion.
If you are concerned that the house is not level, measure down from the soffit at one corner of the house to the top of the foundation and subtract the width of the starter strip minus 1/4". Mark the wall, then transfer the measurement to the other corner of the wall. Snap a chalk line in between the corners at the marks.

Flash the corners of the home by bending a
For cornerposts 12' long or less
Position the outside cornerpost so that the top of the post is 1/4" from the underside of the eave. Extend the bottom of the cornerpost 3/4" below the starter strip.
Before nailing, make sure the post is straight and true. Hang the cornerpost by first positioning a nail at the top of the topmost nail slot. Position all remaining nails in the center of nail slots a maximum of every 8" to 10". Leave 1/8" to 1/16" between the nail head and the cornerpost to allow the cornerpost to move during normal expansion and contraction. (DO NOT NAIL TIGHT.) Follow this nailing pattern on both nail flanges of each post.
NOTE: CedarBoards corners install similar to standard outside cornerposts.
For cornerposts longer than 12' long
Position the outside cornerpost so that the top of the post is 3/8" from the underside of the eave. Extend the bottom of the cornerpost 3/4" below the starter strip.
Before nailing, make sure the post is straight and true. Hang the cornerpost by first positioning a nail at the top of the two top nail slots slot. Position all remaining nails in the center of nail slots a maximum of every 8" to 10". Leave 1/8" to 1/16" between the nail head and the cornerpost to allow the cornerpost to move during normal expansion and contraction. (DO NOT NAIL TIGHT.) Follow this nailing pattern on both nail flanges of each post.
NOTE: When installing any hanging cornerpost longer than 12', position the fasteners at the top of the top two nail slots on each side of the corner.
Transitioning from masonry to stucco
Position the bottom of the cornerpost 3/4" below the starter strip. If the corner is less than 12', leave 3/8" from masonry/flashing to allow for expansion. If the corner is greater than 12', leave 5/8" from masonry/flashing for expansion.

NOTE: If the transition material allows, the bottom 3/4" of the channels may be removed from the outside cornerpost so that the face of the corner may be positioned lower and more in line with the bottom of the siding. This method creates
a transition with more pleasing aesthetics. The outside cornerpost face must still maintain 3/8" or 5/8" clearance from obstructions.
If posts must be spliced for high walls, you have two options:
Option 1
Cut 1" off the nailing flanges and back so just the face of the outside cornerpost remains. Then lap 3/4" of the upper post over the lower post, allowing 1/4" gap for expansion. This method will provide an obvious joint between the two posts, but will allow water to flow over the joint, reducing the chance of water infiltration.
When the bottom edge of a cornerpost terminates into a porch, deck, brick, stone ledge, or roof line, etc., allow 3/8" for every 10' of corner when the ambient temperature is above 40??F; 1/2" for every 10' of corner when the ambient temperature is 40??F or below.
NOTE: It is acceptable to reverse lap outside corners as long as the corners are properly flashed and water can drain from the bottom of the cornerpost.
Option 2
Cut a 6" length of cornerpost and trim the nail flange, receiving channel, and sides until you have just a 90?? bend of vinyl. Using PVC primer and PVC cement, glue the bent piece to the inside of the upper post and lower post. Butt the two posts together.
Nail the entire assembly as one post with all nails in the lower post centered in the nail slots.

Window Flashing
If installing a new window and flashing, refer to the window manufacturer???s instructions and ASTM E2112, Standard Practice for Installation of Exterior Walls, Doors, and Skylights for the proper flashing installation method for the window type and wall configuration of the project.
The width of all flashings is determined by the type of accessory surrounding the window and where the final complete course of siding stops below the window (in the case of the flashing under the window). The flashing should extend past the nail flanges of the accessory. The width of the flashing under the window must allow for the diversion of water.

2.Cut a piece of CertaFlash Flex flashing for the bottom (sill) that is 12" longer than the width of the rough opening. Remove the backer from the flashing and begin applying one end to the jamb of the rough opening 6" above the sill. (NOTE: the tape will extend over the exterior edge of the jamb.) Applying even pressure to the tape with your hands, work your way down the jamb, across the sill, and up the opposite jamb, finishing 6" above the sill. Flex the overhanging tape down onto the wall, covering the weather resistant barrier in weatherboards fashion, again applying even pressure to ensure adhesion.
3.Before installing the window, apply a continuous bead of sealant to the interior of the window???s mounting flange. Install the window according to the manufacturer???s instructions.
4.Cut two strips of CertaFlash BA for the sides (jambs) of the window. Jamb flashing tape should extend a minimum of 3" above the top of the jambs of the window unit and a minimum of 1" beyond the bottom flashing tape installed in step #2, covering the width of the previously installed flashing at the base. Slowly peel release paper off as you press the flashing in place. Ensure the flashing covers all nails and mounting slots on the window???s mounting flange.
5.Cut BA flashing for the top (head) of the opening so it will extend beyond both ends of the jamb flashing Ensure the flashing covers all nails and mounting slots on the window???s mounting flange.
6.Finally, lay weather resistant barrier over the head flashing. Apply CertaTape over both diagonal cuts.

Flash the corners of the home by bending a 20" wide piece of aluminum trim coil 90?? so you have two 10" legs. Cover the entire length of the corner, lapping the upper pieces over the lower pieces.
Position the outside cornerpost with the top of the post 1/8" from the underside of the eave and the bottom of the cornerpost 3/4" below the starter strip. Make sure posts are straight and true before fastening. For advice regarding fastening, please refer to ???Restoration Millwork Installation Guidelines??? (RM003), available online or where Restoration Millwork is sold.
NOTE: It may be necessary to shim or furr out the corners and/or window casings to get the proper pocket height. Always use shimming/furring materials, like Restoration Millwork, that will not rot or decay.
Installing Trimboards around windows
Flash the window according to the manufacturer???s specifications. Once the opening is properly flashed, begin by measuring
the width of the bottom edge of the window and, using this measurement, cut the first section of Restoration Millwork. Apply this piece to the bottom of the window, verifying each end of the section lines up with the edge of the window prior to fastening.
To determine the length of the trim along the sides of the window, measure each side of the window starting at the top of the window and dropping down to the bottom edge of the first piece of millwork applied. Using these measurements, cut the second and third sections of Restoration Millwork. Apply these pieces to the left and right sides of the window, verifying that the top edge of each section lines up with the top of the window and the bottom edge of each section lines up with the bottom edge of the first piece of trim already applied.
To determine the length of the top piece of trim, begin at the left side of the left piece of trim and measure to the right side of the right piece of trim. This measurement should equal the width of the window plus two times the actual width of the trimboards being applied. Cut the final piece of trim and apply it at the top of the window, again verifying that the left and right edges of the cut section line up with the left and right edges of the trimboards in place at the sides of the window.
Once the top section of millwork is in place, apply flashing in compliance with local building codes.

Installing Trimboards around exterior doors
Flash the door according to the manufacturer???s specifications. Once the opening is properly flashed, begin by determining the length of the trim along the sides of the door by measuring each side. Start at the top of the door and drop down to the desired termination point. Using these measurements, cut the second and third sections of Restoration Millwork. Apply these pieces to the left and right sides of the door, verifying that the top edge of each section lines up with the top of the door.
To determine the length of the top piece of trim, begin at the left side of the left piece of trim and measure to the right side of the right piece of trim. This measurement should equal the width of the door plus two times the actual width of the trimboards being applied. Cut the final piece of trim and apply it at the top of the door, again verifying that the left and right edges of the cut section line up with the left and right edges of the trimboards in place at the sides of the door.
Once the top section of millwork is in place, apply flashing in compliance with local building codes.
Occasionally you will need to create a pocket to accommodate a nailing flange:
1.Measure the width of the nailing flange of the window at the opening where you plan to apply the trim.
2.Set the blade depth of your table saw approximately 1/8" higher than the width of the window nailing flange.
3.Set the table saw fence so you are cutting away only the thickness of the saw blade from the trimboard.
4.Make one cut from the back side of the trimboard on your table saw.
5.Check to be sure the trimboard will lay flat against the wall and that all joints are tight before fastening. If the boards do not lay flat against the wall or joints are not tight, repeat the above instructions starting at step 3.

Cutting Panels
To cut panels to size, follow these procedures:
Cross cuts
For a precise cut, use a power circular saw equipped with a sharp,
Cut one or two panels at a time, carefully advancing the saw through the vinyl. A rule of thumb: The lower the temperature, the slower the feed rate.
Panels can also be cut with snips. Use a square to mark the cut line. Start the cut at the top lock and continue to the bottom of the panel.
Rip cuts
Use a utility knife to score the panel along the cut line. Bend the panel back and forth along the score line until it snaps apart cleanly.
Use a combination of tin snips and utility knife to cut panels to fit around windows and doors.
Carolina Beaded factory notches
Overlapping Panels
Refer to the chart on page 35/36 for required overlap spacing.

The STUDfinder??? Installation System combines precisely engineered nail slot locations with graphics to help ensure quick, accurate and secure installation of CertainTeed siding panels on homes with standard 16" or 24" o.c. frame construction.
NOTE: In areas without special
Standard 12' panels feature 10 nail slots every 16", with one of the 10 letters in the word ???STUDfinder??? centered directly under each slot. Locate the first stud and fasten the siding to it in the center of???the nail slot. Ensure that nail/staple penetration is at least 3/4" to comply with ASTM D4756 (specification for vinyl siding installation). Notice which STUDfinder letter appears below the slot.
Go to the next repeat of the letter to find the next stud. For example, if your first stud is at ???T,??? succeeding studs in 16" o.c. applications will also be at ???T??? (every 10th slot).
When you apply the next panel, adjust the overlap as necessary to line up with studs and repeat the steps above, but be aware that the overlapping panels may not use the same letter as your initial panel.
In 24" o.c. applications with standard size siding panels, 2 letters will repeat every other stud (every 15th slot). For example, if the first stud is located at ???S,??? then the next will be at ???i,??? then ???S,??? then ???i,??? etc.

STUDfinder Installation System for Oversized (16', 16' 8", 20' and 25') Panels
CertainTeed???s longer siding panels ??? 16'8" CedarBoards XL, 16'???and 20' Monogram 46L and 25' Monogram 46XL ??? feature 8 nail slots every 16", with one of the 8 letters of the word ???STUDfind??? centered directly under each slot. In 16" o.c. applications, locate the first stud and follow the same basic procedure described for standard size panels: note which STUDfind letter appears below the first nail slot and go to
the repeat of that letter to find the next succeeding stud (every 8th slot).
When installing longer Monogram or CedarBoard panels on 24" centers, the succeeding studs are at every 12th slot; for example, if you start at ???T,??? then the next will be at ???i,??? then ???T,??? then ???i,??? etc.
NOTE: Monogram XL 25' panels must be ???center pinned??? to control expansion and contraction. To do so, locate the center nailing slot of the panel and???drive nails into both ends of the slot (see illustration).???This is only done for one nail slot per panel.
NOTE: Ensure that nail/staple penetration is at least 3/4" to comply with ASTM D4756 (specification for vinyl siding installation). Also be sure to allow 3/8" for expansion and contraction between panel ends and trim when install temperature is greater than 40?? F, and 1/2" for expansion and contraction between panel ends and trim when install temperature is less than 40?? F.

Preparing Wall Surfaces
The key to successful vinyl siding application is proper preparation of the nailing surface. It is essential that you work over a smooth nailing surface. The more level and even the wall surface, the better the finished installation will look.
The steps involved in preparation differ for new homes and old, so choose the instructions (page 28 to 33) that pertain to your project.
Installing the first course
It???s important to work with care and planning as you install siding panels. This is especially true when you???re installing the first course of siding. (See pages 33 to 35 for fastening methods.)
For best results, follow these guidelines:
The key to creating a visually attractive installation is to lap away from areas where people normally walk or gather. For example, on the front wall, work from the corners to the entrance door (so overlaps face away from door).
On side walls, work from the rear corners toward the front. This approach minimizes the effect of lapping and produces the best appearance. Keep lap appearance in mind throughout installation.
NOTE: Lap appearance is also improved when you avoid using panels less than 3' long.
Slide the first panel into the cornerpost recess. Leave room for expansion (see page
Hook the bottom lock of the panel into the interlock bead of the starter strip by applying upward pressure.
Before nailing, double check to make certain you???ve locked the panel along its entire length. A slight upward pressure may be required to snap the interlock securely. Don???t force the lock too tightly, however. You may distort your laps. Nail properly. Also, make certain the panel can slide freely. Start at the center of the panel and work out.
Install the remaining starter course panels, overlapping panel ends (see pages
Remember to leave room for expansion when fitting panels into remaining inside and outside cornerposts.

???Avoid joints above and below windows.
???Leave at least 3' separating joints on successive courses.
???Use short cutoff lengths for fitting at narrow openings between windows.
???Follow the planned pattern when applying the next courses of siding.
Fitting under windows
You???ll probably have to cut panels to fit under windows.
To make this task easier, plan panel positioning as shown at left so a single panel extends beyond both sides of window opening. Follow these steps to measure and cut panels:
Hold the panel in place and mark the width of the window opening. Add
Create a template for the horizontal cut using a small piece of scrap siding. Lock this piece into the lower panel and mark 1/4" below the sill height. This provides clearance for undersill trim. Repeat the procedure on the opposite side of the window. (You can???t assume windows will be perfectly level.)
Transfer the marks from the template to the panel. Connect marks using a straightedge.
Cut the panel, using tin snips to make vertical cuts and a utility knife to make the horizontal cut.

Fitting under soffit
When you reach the last course of siding, you will probably have to rip cut panels lengthwise to fit under soffit.
NOTE: If necessary to ensure proper panel slope angle, make certain to furr out this area.
To cut and install this last course:
Install
Measure from the soffit to the base of upper lock on the previous course of panels. Subtract 1/4". Mark this dimension on the panel to be cut, taking the measurement from the bottom edge of panel. For a more precise cut, repeat this procedure at several other points along the span to be covered by the panel.
Using a square or straightedge, draw a pencil line connecting these points. Then score along the line with a utility knife. Bend the panel back and forth until it snaps. Use a snap lock punch to create tabs on the outside face of the panel, 1/4" below the cut edge. Space tabs every 6".

NOTE: Since you will not nail this last course, it is important that the tabs fit properly in the trim to provide support while allowing movement for expansion.
Finishing the top course
To finish the top course of siding, attach cornice receiver to the top of the wall under the eave or soffit. Trim the top panel to within 1/4" of the cornice receiver. Using a nail slot punch, punch nail slots 1/4" from the trimmed edge of the siding panel, 16" apart. Nail
off the top course, and snap the cornice molding into the cornice receiver. An alternate method is to use
Completion
Attaching objects to siding
All external products (downspouts, shutters, and lights, for example) are attached to walls after you???ve applied the vinyl siding.
NOTE: All external fixtures must be attached to a solid backing (such as 3/4" exterior grade plywood) to provide a secure mounting surface. Never attach a fixture directly to vinyl siding.
When installing external products, you must allow for expansion and contraction of siding.
You can allow for this movement in two ways:
The most convenient way to attach light fixtures is with light blocks. Because they contain receiving channels to hold siding panels, light blocks provide a simple way to allow for expansion.
When attaching other fixtures, drill holes in the siding 1/4" larger than the diameter of screws, bolts, or nails being used to fasten objects. This provides adequate clearance so the siding can move freely underneath attached objects. When attaching objects, do not fasten tightly. It is also recommended that you apply caulk around the screws.
Fitting at light blocks
When cutting panels to fit at a light block, be sure to allow for expansion.

Shutter Installation
The ideal application (a) has a joint between the two shutters where the shutters are secured to the home. In this way, the siding panel is not ???hard nailed??? between the two shutters and the siding is allowed free movement.
When there is no joint between the shutters and when the shutters are secured to the home (b), the shutters??? fasteners do not
allow the siding panel to move. The siding panel then fails to perform because it cannot expand or contract with the temperature changes.
To prevent this, enlarge the holes in the siding for securing bthe
of the fastener.
If possible, stagger the screws securing the shutter so that they do not line up on the same panel. It is also a good idea to apply caulk around the screws.
NOTE: See page 76 for fitting siding into narrow openings.

Preparing Wall Surfaces
For the most part, the wall preparation instructions given for horizontal siding also apply to vertical applications. The key requirement, of course, is that you start with a smooth, level and rigid substrate (plywood, wood composite, rigid foam or fiber sheathing).
NOTE: Never install vinyl siding over open furring strips or studs. Always check with your local building code official.
1/2" foam sheathing
always position topmost nail in topmost full nail slot with vertical applications
center nail in slots
With vertical siding, however, you may have to complete an extra step to provide solid nailing points along the vertical edge of the siding panel. The need for this added step depends on the type of substrate used and the nature of the construction project.
With new construction or remodeling using plywood or wood composite, there are no additional steps. You can nail into plywood and wood composite substrates at any point as long as you do not exceed 12" on center.
In new construction using rigid foam or fiber sheathing, you must install solid wood nailer strips horizontally to studs before applying sheathing. Use 1" x 3" wood furring positioned 12" o.c.
When remodeling over existing wood siding, you must apply rigid foam or fiber sheathing, shimming if necessary to create a level surface.
When remodeling over brick, block, stucco or irregular wall surfaces, apply furring strips horizontally to create a level surface; then apply rigid foam or fiber sheathing. See ???Tips for applying wood furring??? on pages 31 to 32 and ???Applying over stucco???
on page 32. When reviewing the illustrations for those sections, remember that furring strips must be applied horizontally.
Marking a base line
The procedure is virtually the same as that described earlier. However, instead of snapping a chalk line

Wall Panels
Follow the instructions described earlier under the section ???Preparation for Horizontal Siding??? beginning on page 28.
Plan the panel layout
Correctly installed vertical siding should have a balanced appearance. This means that if you were to draw a vertical line down the center point of a wall, you???d have an equal number of panels to the right and left. If you had to trim panels to fit, the
To create this pleasing appearance, divide the space to be covered by a partial panel over both ends of a wall. For example, if a wall required 25 full panels plus 10", you would rip cut two 5" lengths of panel to create the end pieces.
Expansion and contraction
In a vertical siding installation, most of the expansion is downward. So instead of allowing equal space for expansion at both ends of a vertical panel, leave more space at the lower end: allow for 1/3 of the total expansion at the top of a panel and 2/3 of the total expansion at the bottom.
For example, if the total expansion equals 3/4" (3/8" + 3/8"), allow 1/4" at the top and 1/2" at the bottom. If the total expansion equals 1/2" (1/4" + 1/4"), allow 3/16" at the top and 5/16" at
the bottom.
NOTE: Always position top most nail at the top of the top most full nail slot (1a). Center the remaining nails in the slots (1b). When installing siding or accessories vertically, make sure the bottom of the panel can expand downward without interference.
Cut the first of the partial panels (if partial panels are necessary). Mark the cut line by measuring from the nail hem edge. Rip cut the panel. Do not cut off the nail hem. Use a snap lock punch to create locking tabs along the cut edge. Space the tabs 6" apart.
Before installing this partial panel into the outside cornerpost, provide additional support at the cut edge to compensate for the locking channel that was trimmed off.
To do this, insert furring into the channel of the outside cornerpost and nail it to the substrate. After furring, insert a length of undersill trim into the cornerpost and nail it to the furring. Finally, slide the cut edge of the panel into the undersill trim, making sure to engage the snap locks (see illustration).
Using a level, make certain this panel is plumb. Nail every 12". Follow the same nailing procedures described for horizontal siding.

Install the next panel. Lock the panel into the preceding panel, then nail every 12". Continue with succeeding panels.
When necessary, cut panels to fit around doors and windows. When marking the cut, remember to allow for expansion.
The method used to install panels around doors and windows is determined by the need to cut a panel and the position of that cut. If a cut was made next to a remaining
To finish the first course of a wall, cut the final panel to size and install it in an outside cornerpost, using the method described above.
NOTE: The cutting and supporting procedure described above is also used when fitting panels into inside cornerposts.
Installing Gable End Panels
When installing vertical or Board & Batten siding on a gable end wall, you should try to create a balanced appearance.
There are two ways to do this:
You can start from the center of the wall and work toward the sides. Begin by finding the center point of the wall (beneath the peak) and draw a plumb line. Nail two lengths of
NOTE: To guide the cutting of the upper end of the panel, make a pattern duplicating the gable slope. (See page 67.)
Insert the panel into the
Use a level to make certain the panel is plumb. Nail every 12". Continue cutting and installing panels. Then repeat the procedure on the remaining half of the gable end.
If you want to work from one end of the wall to the other, begin by centering a panel under the center of the peak. Mark the position of the panel on the wall, then measure the distance from the left (or right) cornerpost to mark for the left (or right) edge of the center panel.
If you need a partial panel, cut it and install it at the cornerpost, following the procedure described on page 83. Cut the upper end of the panels to proper height and slope, following the procedure described above. Remember to allow for expansion.

Requirements for Proper Soffit Ventilation
Proper attic ventilation is important for any home. The 2009 International Building Code (IBC) Section 1203 Ventilation furnishes a basic guide for determining proper ventilation for any home. The information provided here may under certain circumstances not result in enough ventilation. Therefore, the calculation provided should be used as a guide only.
The IBC guideline requires that any attic or space between the top floor, ceiling and roof must be ventilated. It requires one square foot of ventilation area for every 150 square feet of attic space.
If a vapor retarder of less than one perm has been installed on the warm side of the ceiling or if at least 50% of the required ventilating area has already been provided by gable and vents or ridge vents, you need add only

Drainage Channels
Some building codes require that Cedar Impressions panels be installed so that there is drainage space behind the panel. This space will allow moisture to escape from the panels while preventing water intrusion from the exterior. Information about installing drainage channels is available at www.certainteed.com

Starting on the left side of the wall, hook the bottom edge of the panel into the starter strip and slide the panel into the cornerpost or receiving channel. Leave 1/4" space between the panel and the inside wall of the cornerpost for expansion.
Fasten the panel to the wall by first nailing through the round center hole of the nailing hem at the top of the panel. Then fasten the rest of the panel by nailing through the centers of the remaining nail slots a maximum of every 8" to 16" on center. Provide 1/8"
to 1/16" between the nail head and the panel to allow freedom of movement during normal expansion and contraction. Failure to provide this space between the nail head and the panel will cause the panel to buckle. Do not put a nail into the far right slot until the overlapping panel is positioned for installation.
Install the next panel by using a dual motion of hooking into the starter strip and sliding over the previous panel. This will ensure a proper lap.
Position the overlapping panel so that there is 1/8" to 1/4" between the panels, depending on the panel temperature at time of installation. The spacing may appear larger or smaller than the spaces between the shingles on the panel. This is normal and necessary in order to allow for expansion and contraction.

Making the starter course
Gable installations properly terminate with a single round at the peak. To create this effect, you usually have to adjust the height of the starter course.
To determine the height of the starter course, calculate the number of rows required to complete the gable.
Use the following formula:
Gable height (inches) ?? 12.5 (face exposure) = courses required
NOTE: Gable height is measured from inside the horizontal receiving channel to the peak (allowing 1/4" at top and bottom for expansion).
For example, with a 68" gable height, the calculations would be 68 ?? 12.5" = 5 with a remainder of 0.44. This means you would need 5 full courses plus 0.44 x 12.5" (face exposure of panel) = 5.5" measured from the top edge of the gap on the upper course (illustrated). This is the visible height for your starter course.
The visible height is the vertical dimension of the panel you???ll see below the first full row of rounds.
Once you???ve determined the visible height of the starter course, mark this dimension on a
Cut and use the top section, which contains the locks, as your starter course. Cut enough panels to span the base of the gable.

Hanging the starter course
To end up with a single ???round??? centered at the peak of the gable, you must properly locate the first starter panel.
Begin by marking a vertical plumb line from the peak.
Then measure and mark the finished height line. In our example, using a starter course with a
With your ruler inserted into the pocket of the lower
The point where the plumb line and the horizontal level line intersect marks the starting point for hanging the first starter course panel (if the first starter panel intersects the plumb line).
Determine whether you will center a ???scallop??? or a ???V??? at the starting point. This decision is based on the number of courses required to complete the gable.
The rule of thumb is:
Center an upper scallop if the initial calculations had less than 0.5 courses remaining (0.44 in our example).
Center the gap or ???V??? of the upper course if more than 0.5 courses remained. (In our example we require 5.44 courses, so we would center on a scallop.)
More than one panel will probably be required to reach the plumb line. Measure from the plumb line into the pocket receiving channel (leaving 1/4" for expansion) as illustrated at left.

If you require an odd number of courses (i.e. five full courses plus starting course), subtract 8" from the distance from the plumb line to the left receiving pocket (remember to allow 1/4" for expansion).
If you require an even number of courses (i.e. 6 full courses plus starting course), subtract
NOTE: The 8" and
For example: If the measurement required to the plumb line (minus 8" for an odd number of full courses) is 152", then 152"?? 32" = 4 full panels plus 0.75% of one panel or 24" measured from the edge of the texture on the right side (temperature indicator side).
Create a cutting guide as described earlier for gable applications and trim the first panel (for this example) at 24". Continue to hang the remaining starter course strips, remembering to center nail first.
Installing first full panel
It is important to stagger the panels, as described in this section. The easiest way to determine the length of panel required is to measure from the alignment line on the nail flange of the starter panel to the edge of the roof slope (see illustration).
Using this measurement, drill a hole centered in the remaining nail flange as described earlier. Lock the first full exposure panel to the starter course after trimming for roof slope.
After locking panel in place, center pin the panel.
Lapping remaining panels
The remaining panels to be installed must be lapped in accordance with the current temperature.
Repeat this process for the entire course.
At the end of each course, trim panels to the gable angle. Be sure to allow for expansion at the

Replacing a Damaged Cedar Impressions
Panel (Option 2)
You will need a hammer, wood chisel, and hacksaw or utility knife.
Use a wood chisel to remove the lock tabs on the top side of the damaged panel. Lock tabs can be located by using the chisel to slightly lift the panel locked into the upper portion of the damaged panel.
After locating the lock tabs, place the bevel of the chisel down against the face of the damaged panel; use a hammer and the chisel to knock off the lock tabs of the damaged panel. Then remove the nails on the damaged panel, and pull the panel down and remove it.
On the replacement panel, use a hacksaw or utility knife to cut the lock tabs to half their original length. Slide the replacement panel back into the position of the removed damaged panel.
Use the hammer handle to put pressure against the bottom butt of the replacement panel to force pressure upward enough that the replacement panel will engage with the panel above.
Drill a nail hole in the center of the top portion of the replacement panel. Then use a colored trim nail to control the direction of expansion of the replacement.
NOTE: While this method provides an aesthetically acceptable replacement, it does not actually secure the panel to the wall. The only way to secure a replacement panel with nails is to remove the siding from the top of the wall down until the damaged panel can be removed.

Northwoods S7" and S9" Shakes
Overview
The installation of a Northwoods Shakes or Shingles panel is unique in that the lap joint is hidden in the ribs between the shake or shingle pattern. Positioning the laps in the rib area requires that special installation procedures be followed to maintain product performance and aesthetics.
Panels must be installed from right to left. The left panel will overlap the right panel.
Factory laps
All lap joints are cut at a predetermined point on the panel during the manufacturing process. All male laps must be factory cut. Female laps may be field cut using the gap. However, do not cut along the edge of the gap; leave 3/16" of the gap for the overlap.
NOTE: Do not drive
Center pinning
Vinyl siding expands and contracts as the temperature of the panel changes. To maintain the proper rib width at the lap joint, you will have to limit the movement of the panels. To do this, you must center pin each panel. Center pinning prevents the rib width at
the lap joint from becoming too wide or too narrow.
Center pin each panel regardless of length
Install the siding according to one of the following methods, depending on whether the substrate is or is not fully nailable.
NOTE: The siding must be applied over a rigid sheathing that provides a smooth, flat surface or an underlayment (such as wood, wood composition, rigid foam or fiber sheathing) that is no more than 1" thick. Do not apply siding directly to studs. See pages 21 to 26 for additional information about proper sheathing and substrates.
Lock the right side panel into place on the starter strip. Allow room for expansion and contraction in all accessory pockets:
???1/4" if the ambient temperature is above 40?? F.
???3/8" if the ambient temperature is below 40?? F.

temperature marks
Locate the mark at the center of the panel. Use the nailing slot closest to this mark. Center pin the panel in this location using one of the following options:
1.Install a nail on both ends of the same nail slot.
2.Drill a 3/16" diameter hole through the nail hem and substrate, and place a single fastener through this newly
drilled hole.
Position nails in the center of the remaining slots, 16" apart. Leave adequate room between the fastener head and the nail flange for expansion and contraction (approximately 1/16" to 1/8").
Do not hard nail these fasteners.

If the ambient temperature is between 45??F to 80??F, lap the panel to the second (65??) mark.
If the ambient temperature is greater than 80??F, lap the panel to the third (100??) mark.
Fasten the panel according to the procedure described earlier.
Continue the first course of siding, remembering to center pin every panel.
Start the next course of siding from the right side, repeating the earlier steps. Offset the laps from course to course a minimum of 2 feet.

Installing CedarBoards Insulated Siding
CedarBoards Insulated Siding will help even out wall surfaces. However, to minimize extremes in the peaks and valleys of uneven walls, you may have to repair the underlayment. Make sure
the substrate is smooth, flat, and weathertight. If the surface is significantly uneven, apply 1/4" (minimum) foam sheathing before installing CedarBoards Siding. If the wall surface is smooth, use standard underlayment practices.
Horizontal Siding
The key to creating a visually attractive installation is to lap away from areas where people normally walk or gather.
For example, on the front wall, work from the corners to the entrance door (so overlaps face away from door).
On side walls, work from the rear corners toward the front. This approach minimizes the effect of lapping and produces the best appearance. Keep lap appearance in mind throughout installation.

The STUDfinder??? Installation System combines precisely engineered nail slot locations with graphics to create a siding panel that is designed to help ensure quick, accurate and secure installation. The nail slots are positioned 16" on center to allow for alignment with studs, with STUDfinder graphics centered directly under each nail slot.
Locate the first stud and fasten in the center of the nail slot. Ensure that nail penetration is at least 3/4" into framing members to comply with ASTM D4756 (specification for vinyl siding installation). Notice which STUDfinder letter appears below the slot.

Around windows and doors
Because insulated siding is thicker than hollow vinyl siding, windows, doors, and other openings may have to be built out to avoid looking recessed. Use wood shims and either aluminum trim coil or vinyl lineals to build out openings. In some cases, the foam backing in CedarBoards siding will create enough stiffness to span over or under a window without additional support.
If you are using utility trim or dual undersill trim to secure the panel, shim the trim to accommodate the thickness of the siding panel. Remove the top 1" of the foam backing so the top of the panel fits into shimmed trim. Use a snap lock punch to raise tabs every 6" to lock the panels into the trim.
When you cut a siding panel to fit around an opening, use a nail slot punch to create additional nail slots. Fasten through these additional nail slots to secure the panel. Make sure the face of the

Overlapping panels

To correctly overlap the panels, slip the vinyl edge of the bottom portion of the seam between the foam and the vinyl panel.
For standard length CedarBoards, slide the panels together until the foam ends touch or you achieve a minimum overlap of 1". The maximum overlap should not exceed
For CedarBoards XL:
???Above 40??F, overlap the panels
???40??F and below, overlap panels 1" to
TIP: For ease of handling extended length product, we recommend carrying the panels on edge, not flat.
Measuring CedarBoards
When lapping two factory laps, you will often butt the panel foam and not lap 1" as in standard vinyl applications. This mandates a different approach from standard practice when you measure CedarBoards panels.
When filling in a piece to end a course of siding, hold the tape tight into the receiver of the corner post,
As you measure on the full piece to be cut, measure from the foam on the factory end that butts to the existing piece to your desired measurement. This will ensure a butt fit on the foam and the proper room in the receiver for expansion and contraction.
Creating a field lap
For best appearance, lap factory ends only. If you must lap a non- factory end, you will first have to remove the foam and adhesive.
Cut the foam back approximately 3/4" on the field cut, fabricate the top and bottom panel end notches, and always use a factory notch as the overlapping panel. Place the

Vertical Siding
NOTE: Never install vinyl siding over open furring strips or studs. Always check with your local building code official. With vertical siding, however, you may have to complete an extra step to provide solid nailing points along the vertical edge of the siding panel. The need for this added step depends on the type of substrate used and the nature of the construction project.
With new construction or remodeling using plywood or wood composite, there are no additional steps. You can nail into plywood and wood composite substrates at any point as long as you do not exceed 12" on center.
In new construction using rigid foam or fiber sheathing, you must install solid wood nailer strips horizontally to studs before applying sheathing. Use 1" x 3" wood furring positioned 12" on center. For further information regarding applying wood furring over stucco, please refer to page 32.
When remodeling over existing wood siding, you must apply rigid foam or fiber sheathing, shimming if necessary to create a level surface. When remodeling over brick, block, stucco or irregular wall surfaces, apply furring strips horizontally to create a level surface; then apply rigid foam or fiber sheathing.

Section 13 ??? Miscellaneous
Cleaning Vinyl Siding
Vinyl siding resists most common household stains, but it will become dirty like any product exposed to atmospheric conditions. In areas not exposed to direct sun and rain, periodic washing with a soft bristle brush and clean water from a garden hose may be necessary to remove surface dirt. Chalk may also accumulate on the surface. This is a normal condition for pigmented materials exposed to the elements.
For the best appearance, clean vinyl siding at least once a year.
To remove soil, grime and chalk from siding, use a garden hose, a soft bristle brush, and a bucket of soapy water. (You can also use the solution described below in the section about mildew.)
To minimize streaking, wash the house from the bottom up.
Thoroughly rinse the siding with clean water from a garden hose. Avoid prolonged or high pressure rinsing of open ventilated areas. Keep cleaning solution off surrounding fixtures and surfaces not scheduled for washing.
NOTE: We do not recommend power washing vinyl or polymer siding as it can cause moisture intrusion, damage, and/or discoloration.
Stubborn stains
If you can???t remove especially stubborn stains using normal household detergents, request a cleaner from your siding contractor or your local building materials retailer. Always test any cleaner on an inconspicuous area before full use.
Mildew
Mildew may be a problem in some areas, especially warmer climates with consistently high humidity. Mildew appears as black spots on surface dirt and is usually detected in areas not subjected to rainfall, such as under eaves and porch enclosures. To remove mildew, prepare a solution as follows:
1/2 cup detergent (Tide, for example)
2/3 cup trisodium phosphate (Soilax, for example)
1 quart 5% sodium hypochlorite (Clorox, for example)
3 quarts water
CAUTION: Greater concentration may cause damage to the siding and soffit.
If the above solution does not readily remove mildew spots, ask your siding contractor or your local building materials retailer for a mildew cleaner.

Siding over Asbestos
Vinyl siding retrofit over asbestos
This is a recommendation from the Vinyl Siding Institute after discussions with Federal EPA officials. Because local regulations supersede federal regulations, local EPA officials should be contacted in the area where the work is being done.
The most desirable practice is not to disturb the existing siding on the home. Apply sheathing over the existing asbestos siding, and then apply vinyl siding over the top of the sheathing. The sheathing will serve to flatten the wall and also retain any breakage of the cement asbestos siding. Nails should be long enough to penetrate through the sheathing and existing asbestos siding and into the wall studs.
If there is a need to level or flatten a wall, apply furring strips over the sheathing.
In the case where the homeowner wants the existing cement asbestos siding removed completely, removal should be done by a professionally trained asbestos removal crew.
Please note that some jurisdictions require all asbestos removal to be performed by a trained asbestos removal crew.
Historic Restoration
Vinyl Siding Institute recommended guidelines
If a building is in an historic area or has been designated an historic building, be certain that approval for the use of vinyl siding has been obtained from the local historic society. This applies to building additions as well.
Before proceeding to
Do not damage or remove the original siding. If at all possible, do not alter the original structure so that the application of vinyl siding is reversible (i.e. the original would remain intact and some time in the future, if desired, the vinyl siding could be removed).
