2 TM Maibec Resistech Panel, Shingle Strips and Trims Solid Colours This installation guide applies to the installation of Maibec Resistech TM solid colour panels, shingle strips and trims only. Carefully read this entire guide to understand all of the necessary steps and requirements for ensuring proper installation. For assistance, please contact Maibec s technical service toll-free at , Monday to Friday from 8:30 a.m. to 4:30 p.m. (Eastern Time) For the installation requirements for Maibec Resistech TM lap siding and soffits, please consult the installation guides for these products. COMPLIANCE WITH MAIBEC S INSTALLATION, STORAGE AND MAINTENANCE REQUIREMENTS, AND WITH ALL APPLICABLE BUILDING CODES IS MANDATORY. PROBLEMS CAUSED BY FAILURE TO COMPLY WITH THESE REQUIREMENTS AND CODES MAY NOT BE COVERED Maibec Resistech TM engineered siding is for exterior use only. This installation guide has been created according to Maibec s requirements as well as to the requirements in the Louisiana-Pacific Corporation Installation Guide. Maibec s requirements prevail over those of Louisiana-Pacific. Drawings in this document are not to scale and are used solely to illustrate best practices. All dimensions in this document are given in inches. 1. BASIC PRINCIPLES FOR INSTALLING SIDING Exterior siding is essential for protecting a home against water infiltration, but is not watertight. Water accumulation behind the siding can cause it to warp or swell, mould to form and even lead to rot inside the wall. This will affect the siding s performance, durability and appearance. 1.1 MANAGING WATER The following requirements must be respected to properly manage water: Water must be able to drain away freely between the siding and water-resistive barrier. Install flashing over all openings, flat surfaces and wherever moisture drainage is needed. Flashings must have a slope outward at an angle of at least 6% for adequate water drainage. Use weather-seal tape/membrane around windows, doors and all other openings to ensure a tight seal with the water-resistive barrier. This will protect the wall from water infiltration. No horizontal furring strips or surfaces at the bottom of walls to prevent water accumulation. Install gutters and kick out flashings on roofs. ALLOW A MINIMUM CLEARANCE OF: FIGURE 1 OPEN ON TOP CONTINUOUS DRAINAGE OF INFILTRATED WATER OPEN AT BOTTOM FIGURE 2 FIGURE 3 FIGURE 4 6% SLOPE 8" 2" 2 8" from the ground - 2" from adjacent horizontal structures space between the siding and the COMPLIANCE WITH MAIBEC S INSTALLATION, (e.g. STORAGE decks, AND low MAINTENANCE walls, roof shingles) REQUIREMENTS, flashing AND over WITH all ALL openings APPLICABLE BUILDING - between siding and flashing

3 Maibec ResistechTM Panel, Shingle Strips and Trims Solid Colours 1.2 VENTILATING THE WALL Continuous wall ventilation will allow heat and moisture to escape from between the siding and the insulating material. Using furring strips, create ventilated spaces (called air gaps or rainscreens) and leave a minimum open space at the bottom and top of walls to allow air to enter and exit across the entire height and width of the wall. Wall ventilation is especially important when darkcoloured siding and/or foam insulation panels are used. Dark siding absorbs more heat and is more prone to thermal expansion. Foam insulation panels also tend to trap heat. Maibec ventilated strips* will allow proper water and heat management while preventing potential rodents and certain insects from getting in behind the siding. - Ventilated spacer: Used between furring strips at the top and bottom of panels; supports panels while ensuring adequate ventilation and drainage. - Ventilated universal "L" strip: Top of windows, top and bottom of walls, and other types of installation. The addition of spacers is required depending on where the ventilated strip is used. - Ventilated "J" strip: Bottom of windows and tops of walls. - Ventilated universal band: Can be folded and cut on-site to meet any installation requirement. *If non-maibec ventilated strips are used, they must have a minimum 50% opening to ensure adequate ventilation of the wall. FIGURE 5 MOISTURE CAUSED BY HEAT FROM THE SUN AND WATER VAPOUR EXPELLED FROM THE INTERIOR CAN ESCAPE AIR GAP BETWEEN TWO S AIR OUT OPENING AIR IN OPENING 1.3 PROTECTING THE INTEGRITY OF THE SIDING To protect the integrity of the product, always follow the instructions for touching up and nailing the siding. Apply touch-up paint to any bare wood to seal it. This will keep water from seeping into the strands, ensuring the optimal performance of the siding and paint while preventing degradation. [SECTION 5] Correct nailing will result in a stable, long-lasting installation. [SECTION 4] 2. STORAGE Keep the siding in a dry, unheated, well-ventilated area away from the elements and at least 6" from the ground. Never let it come into direct contact with the ground. Cover any unused siding with its original packaging at all times, even during installation. If the original packaging is no longer in good condition, cover the siding with a waterproof tarp. FIGURE 6 MINIMUM 6" FROM THE GROUND 3

Have touch-up paint on hand. Inspect each piece prior to installing it. Never install a product that appears to be or that you think may be defective. Installed defective products are not covered by the warranty. Contact Maibec at NOTE: Maibec sells sealant for stock program products but not for custom colour products. Be sure to have a sufficient amount of ASTM C920-approved, minimum Class 25 sealant on hand for sealing butt joints, gaps between siding and trim and all other gaps as needed. Maibec does not recommend customizable sealant. For a list of ASTM-compliant sealant, go to maibec.com. 3.2 CONSULT THE BUILDING CODES Make sure you are familiar with the specific requirements of all applicable federal and provincial building codes and municipal by-laws for your region with respect to installing siding, water-resistive barrier, sealant, etc. For the water-resistive barrier and the sealant, follow the manufacturers instructions. For more information, see the National Model Construction Codes on the Government of Canada s website at nationalcodes.nrcc.gc.ca 4. INSTALLATION SYSTEM Maibec Resistech TM siding is installed with Maibec hot dipped galvanized steel ring shank corrosion resistant nails with textured head as described below. These nails must be ordered at the same time as your siding. DO NOT USE STAPLES. 4.1 NAIL SPECIFICATIONS The nails specified below ensure the required minimum real penetration of 1 into solid wood. These nails are available only from Maibec. 8d (2 ) hot dipped galvanized steel ring shank Maibec coil nails with: A minimum.095" shank A minimum.219" head diameter Rings starting at from the head FIGURE 7 2 If Maibec Resistech TM siding is installed in Coastal regions*, unstained stainless steel grade 316 ring shank nails must be used for installing siding and trims. These nails must have the same features (shank, head, length and ring pattern) as that of galvanized steel ring shank nails described above. Failure to comply with this requirement will void the warranties. CORRECT INCORRECT * APPLICABLE COASTAL REGIONS INCLUDE THOSE LOCATED LESS THAN 600 M (2,000 FT) FROM THE COASTLINE IN THE ATLANTIC PROVINCES (NEW BRUNSWICK, PRINCE EDWARD ISLAND, NOVA SCOTIA, NEWFOUNDLAND AND LABRADOR), IN SAINT-PIERRE-ET-MIQUELON, AND IN THE U.S. EAST COAST STATES.

5 Maibec ResistechTM Panel, Shingle Strips and Trims Solid Colours 4.2 NAILING Ensure nails have a minimum real penetration of 1 in a solid substrate (wood, plywood or OSB). Nails must also penetrate into the structure. This penetration is obtained by using two nails to secure the board at the required locations. Do not overdrive nails. Nail head should seat firmly to face of siding but not be overdriven to distort the siding surface. All exposed face nails must be properly sealed in a manner that prevents moisture intrusion and water buildup.

TOUCH-UPS To ensure the optimal performance of the siding and paint, all cut panels, batten, shingle strip edges and trims must be resealed to prevent water from seeping into the strands and causing degradation over time. Apply touch-up paint to all cut or planed surfaces and to all exposed substrate, even if it will not be visible after the siding is installed. Always touch up boards BEFORE installing them. FIGURE 9 FIGURE 10 RESEAL ALL CUT BOARDS APPLY PRECISELY DO NOT SPILLOVER OR OVERBRUSH Apply touch-up paint to all visible nail heads (and some invisible nail heads - FIGURE 8). Most of these nails can be found on panels, battens, shingle strip edges installed above doors, above and under windows, along the starter course, on corner trims, as well as around doors, windows and other openings on the wall. Use a polyester, nylon or any synthetic applicator with firm bristles approved for water-based coatings. Touch-up paint is included with your order. If you need more, you can purchase a Maibec-approved paint from your retailer. See the list of Maibec-approved paints in the Painting Guide at maibec.com. NEVER APPLY TOUCH-UP PAINT OVER NON-DAMAGED OR UNCUT FACTORY COATED MATERIAL. IMPROPER APPLICATION OF THE TOUCH-UP PAINT CAN RESULT IN DIFFERENCES IN COLOUR THAT WILL NOT NECESSARILY APPEAR IMMEDIATELY, BUT WHICH MAY BECOME MORE NOTICEABLE OVER TIME AFTER PROLONGED EXPOSURE TO ULTRAVIOLET RAYS. For more information, consult the touch-up guide that accompanies the touch-up paint or go to maibec.com. 5

6 6. Use a ASTM C920-approved, minimum Class 25 sealant for sealing butt joints, gaps between siding and trim, and all other gaps as needed. 7. GENERAL STRUCTURE OF THE WALL Siding and trims must be installed over: A standard maximum 16" stud built wall. Nailing base consisting of furring strips and OSB (oriented strand board) or plywood, or foam insulation panels combined with OSB or plywood. For siding panels only: Ventilated spacer between furring strips at the top and bottom of panels. Approved water-resistive barrier (Tyvek, Typar, etc.). Flashing installed over all openings, flat surfaces and wherever moisture drainage is needed. Weather-seal tape/membrane around windows, doors and all other openings to ensure a tight seal with the water-resistive barrier. This will protect the wall from water infiltration. Ventilated barriers preventing rodents and certain insect from infiltrating behind the siding. Check the structural integrity of the wall prior to installation. It must be solid and straight, with an adequate nailing base to hold the siding securely in place. Maibec cannot be held responsible for any damage to the siding caused by the movement of a structure that has not been built on a frost-protected foundation. FIGURE 11 WATER-RESISTIVE BARRIER "L" FOUNDATION (PANELS ONLY) Verify that the wall s watertightness is ensured by a properly installed water-resistive barrier and appropriate flashing. If you are using insulating concrete forms (ICF), please contact Maibec for technical assistance. 8. MAIBEC RESISTECH TM PANEL AND SHINGLE S INSTALLATION MAIBEC RESISTECH TM PANEL CAN ONLY BE INSTALLED VERTICALLY. MAIBEC RESISTECH TM SHINGLE S CAN ONLY BE INSTALLED HORIZONTALLY. 8.1 MANDATORY VERTICAL S Vertical furring strips create a ventilated space (called an air gap or rainscreen) between the siding and the waterresistive barrier. This space allows any water that may infiltrate behind the siding due to driving rain, wind or morning dew to escape rather than accumulating behind the siding. It also allows water vapour from inside the building released by the water-resistive barrier to escape without damaging the wall. MANDATORY SPECIFICATIONS 1" x 3" furring strips (1" x 4" or 2" x 3" is acceptable) must be used. This requirement applies especially when foam insulation panels less than 1 thick are used. Furring strips must be kiln-dried with a moisture content below 19%. They must be new, straight and undamaged. If the siding is being installed as part of a renovation project, replace all existing furring strips with new compliant strips. 6

7 Maibec ResistechTM Panel, Shingle Strips and Trims Solid Colours 8.1 Mandatory vertical furring strips (cont d) INSTALLING S Install furring strips vertically and secure them firmly to the structure using one staggered nail or angle screw every 6" maximum. Nails/screws must have a maximum penetration of 1 in the structure. [FIGURE 12] Furring strips should have a maximum spacing of 16" on centre. Maibec prohibits a spacing of 24" between furring strips. Furring strips must extend beyond the concrete foundation line by 1" minimum to ensure the overlap of the siding and the foundation. FIGURE 12 STRUCTURE 6" MAXIMUM BETWEEN NAILS/ SCREWS 16" BETWEN S FOUNDATION S MUST EXTEND BEYOND THE FOUNDATION 1" MINIMUM FIGURE 13 NEVER INSTALL S DIAGONALLY, WHICH WILL IMPEDE VENTILATION OF THE WALL AND PREVENT WATER FROM DRAINING FREELY. NEVER INSTALL S HORIZONTALLY AT THE BOTTOM OF WALLS OR AROUND DOORS AND WINDOWS. [FIGURE 13] FORBIDDEN IMPORTANT - If foam insulation panels exceeding 1" in thickness are used or if the siding is installed in a high wind speed area, 1" x 4" or 2" x 3" vertical furring strips must be installed over the insulation to hold it in place. It is the installer s responsibility to ensure the furring strips are firmly nailed/screwed to the structure and spaced a maximum of 16" on centre with a minimum nail/screw penetration depth of 1. Nails/screws cannot be spaced further apart than the width of the siding. Maibec and Louisiana-Pacific will assume no responsibility for any damage or condition arising from the use of foam insulation panels. 8.2 PREPARING THE BOTTOM OF WALLS AND THE STARTER COURSE FIGURE 14 BOTTOM OF WALLS Install siding at least 8" from the ground to avoid exposing it to splashing rain and soil moisture. [FIGURE 14] Siding should never come into direct contact with the ground. Cut the surface of the siding such that the rotation of the blade cuts downward on the prefinished surface. 8" FROM THE GROUND 1" "L" 7

8 8.2 Preparing the bottom of walls and the starter course (cont d) STARTER COURSE WITH MAIBEC S Use one of the following ventilated strips* for the starter course: - Ventilated universal "L" strip: The ventilated universal "L" strip ensures proper ventilation and drainage behind panels and shingle strips. A shim must be installed along the bottom of the ventilated strip to create the correct angle for the shingle strip. The shim consists of 1 high by thick piece of siding and must run the entire perimeter of the building. Touch-up stain should be applied to the entire shim. [FIGURE 15] - Ventilated universal band: Use the universal band if furring strips exceed 3/4" in thickness or if insulation panels are used. The ventilated band will cover the furring or insulation panels, preventing potential rodents and certain insects from getting behind the siding. The addition of a spacer is required for shingle strip. *If non-maibec ventilated strips are used, they must have a minimum 50% opening to ensure adequate ventilation of the wall. Install the ventilated strip with a precision (laser) level or other type of level directly over the furring strips. The bottom of the furring strips should reach to the bottom of the ventilated strip. Secure with 2 nails horizontally every 16". - Ventilated spacer: Used between furring strips at the top and bottom of panels; supports panels while ensuring adequate ventilation and drainage. FIGURE 15 "L" 16" 8.3 NAIL PLACEMENT ON SIDING MAIBEC RESISTECH PANELS (VISIBLE NAIL SIDING) Install panels over furring strips with a maximum spacing of 16" on center. The edges of panels with overlap grooves must fall directly in the centre of the furring strip. Space nails 6" on center along the vertical edges of the panel. Nails spaced 6" on center along the bottom groove will be covered by the overlap flange. Nails spaced 6" on center on the overflap flange should be 1" from the edge of the panel. Use 2 nails at the top and bottom of panels between furring strips centered at 5. Nail panel on intermediate furring strips at 12" on center vertically. [FIGURE 26] Nails will be exposed on the overlap flange, along the horizontal edges at the top and bottom of panels and below window sills. Apply touch-up paint to all visible nails. It is recommended to use a fine-tooth carbide blade to ensure as smooth a cut as possible and to maintain the lifespan of the blade. Cut the surface of the siding so that the rotation of the blade cuts downward on the prefinished surface. 8

[FIGURE 17] FIGURE 17 FIGURE 16 PANEL 1" BATTEN TIP Space battens symmetrically on the wall. Battens should cover the nails at panel joints. [FIGURE 16] 1/8" 1/8" PANEL WITH 1" X 2" BATTENS SHINGLE S (VISIBLE NAILS) Start by nailing a 1 high by thick shim to the ventilated strip. [FIGURE 18] FIGURE 18 Staggered shingle strip: When installing the staggered strip over another material, the starter strip should be installed with the right side facing down. Continue installation according to the instructions in the next point. Working from left to right, install the first row of siding so that the random edge does not extend more than below the shim. Cut the left edge so that the siding butts snugly against the corner board, with a gap of 3/16. Make sure the other edge of the strip falls against a stud so that it can be nailed in place. 1 3/4" OVERLAP 10" EXPOSURE 3/4" Straight shingle strip: Working from right to left, install the first row of siding so that the straight edge does not extend more than below the shim. Cut the right edge so that the siding butts snugly against the corner board, with a gap of 3/16". Make sure the other edge of the strip falls against a stud so that it can be nailed in place. 1" Use the "alignment groove" in the edge of the shingle strip as an automatic guide for overlapping each row of shingles. At least 1 3/4" of the lower part of the groove should be covered. Nail 3/4" from the bottom edge to penetrate both layers of siding. All siding joints should fall on studs. Double nail at the edges of shingle strips. [FIGURES 19, 20 AND 21] "L" 8" FROM THE GROUND 9

[FIGURE 26] Verify course alignment with a level at every panel and adjust as needed. A maximum gap of 1/16" between panels is considered normal. If you are installing one panel above another, leave a gap between flashing and the upper panel. [FIGURE 27] Make sure there is a ventilated spacer running along the top and bottom of each panel to properly support it and to provide adequate ventilation and drainage. 12" 5 6" FIGURE /8" AT THE BOTTOM AND TOP OF THE PANELS 1" BATTENS If using battens, make sure they are not longer than the height of one storey. [FIGURE 28] SHINGLE S Depending on whether you re following the random or straight strips installation method, begin installing the subsequent rows in the same way, but cut each length so that joints are staggered. For best results, shorten the first piece of the second row by 16" and the first piece of the third row by 32". Repeat this sequence every three rows. [FIGURE 19] FIGURE 27 FIGURE 28 "L" PANEL PANEL PANEL BATTEN 9. TRIMS AND CORNERS Trims should be thick enough so the siding does not extend beyond the face of the trim. 9.1 CUTTING TRIMS For the cleanest cut and longer blade life, a fine-tooth carbide tipped blade is recommended. Cut the surface of the trim such that the rotation of the blade cuts downward on the prefinished surface. 11

12 9.1 Cutting trims(cont d) Do not rip and/or rout the trim, as FIGURE 29 it will leave the edges unprotected. All cut trims must be resealed to prevent water from seeping into the strands. Apply touch-up paint to all cut surfaces and/or to all exposed substrate, even if it will not be visible after the siding is installed. TOUCH-UP NO 45 DEGREE NEVER NAIL DO NOT MITER DO NOT MITER Always touch up boards BEFORE PAINT DIAGONAL INTO EDGES EDGES CUT THE installing them.

At all times, the installation should allow rainwater to drain freely and prevent pooling water from ice dams from penetrating behind the siding. Leave a 2" space between adjacent horizontal structures and a space between the siding and the flashing. [FIGURE 34] Install the ventilated starter strip directly to the furring at the bottom of the wall.

14 11. WINDOW AND DOOR FINISHING DETAILS The siding s installation must allow for continuous ventilation and adequate drainage above and below all openings. Maibec offers a full range of ventilated trims to ensure this. If you plan to install Maibec Resistech TM trims, you must properly set the window or door depth according to the thickness of the furring strips, the siding being installed and the trim. The trim must not extend too far past the window or door frame in areas where water can accumulate (header and sill). If the siding butts to the frame, the frame must be as deep as the thickness of the wall plus the thickness of the siding. Always install trims before installing the siding ABOVE WINDOWS Flashings over openings must: Have a slope outward at an angle of at least 6%. Minimum spacing between flashing and the siding to allow for adequate drainage and air flow. Cover the building element below it vertically by at least. Projection of at least 1/4" beyond the outer face of the building element below it. A shim must be added to the row of shingle strips installed at the tops of windows. See section 8.3 for more details. The ventilated spacer is required between furring strips at the bottom of the panel.
