Failure to comply with the installation guide voids the warranty.

GENERAL INFORMATION

Prior to the installation of the siding, make sure to:

Make your openings watertight in accordance with the type of air barrier you have chosen. Please refer to the manufacturer's recommendations.

Although the wood you have received has been heat dried to less than 3 % humidity, it is possible to see a rise of humidity on the walls exposed to rain. This causes a normal expansion of the planks on both width and length. However, this movement is absorbed by the overlapping of the planks and the 45º cuts. Protect your investment: don't leave your siding needlessly exposed to bad weather as it may amplify the expansion of the wood.

During the installation process of the siding, make sure to:

• Never let your siding be in contact with the ground. A minimum distance of 6" is required.
• Never place your siding in direct contact with the roof. A minimum distance of 2" is recommended.
• Never let your siding be in direct contact with an insulating material. An air space must be maintained between the wall and the siding.
• Wood can show variations in its coloration. Therefore, the installer should position the planks carefully to create an attractive colour pattern.

INSTALLATION

1) Storage

Siding must be protected from bad weather. Use the protective tarp provided to cover the siding. If possible, store the siding inside. Lay down plastic sheeting on the ground and place the siding on 3 wood blocks to keep the wood away from the ground and spread the load evenly.

2) Lathing (Figure A and B)

Mandatory for all siding profiles.

An air space of 3/4" must be created by the lathing process.

Lath dimension: 1 "X 3". Make sure you have good quality laths. Remove checking, knot holes as well as any decay.

Spacing between laths:

• Horizontal and vertical installation: 16" O/C;
• Diagonal installation: 12" O/C. Laths should be perpendicular to the siding.

3) Nails and nailing (vertical or horizontal)

Use spiral shank stainless steel nails, 50 mm head, 16 gauge, compliant with the ACNOR B 111-1974 standard. According to the siding profile and dimensions, one or two nails must be used.

We recommend the FSB15212SS2-1/2 " Bostitch or Benco stainless steel nails, 15 gauge, and the N62FNK-2 Bostitch or Hitachi NT65MA3 nailer.

Follow these instructions carefully :

Failure to comply with the installation guide voids the warranty.

8" Plank (Figure A)
Two nails for each plank, 16" apart .
The first nail should be between 3/4" and 1" from the bottom edge of the plank and the second nail 2-1/2" from the top edge. 

6" Plank ( Figure B)
Nail every 16", between 3/4” and 1" from the bottom edge of the plank.
Nail must penetrate the center of the lath.

4) Spacing between planks (Figure C)

Spacing is required. Do not tighten planks together. Follow the reference line to create the right plank spacing to allow moisture expansion. If there is no reference line, leave a space at the edge of the planks of a minimum of 1/8" for 6" siding and of 3/8" for 8" siding.

5) Joints (Figure D)

Whenever a joint is required, cut planks to be jointed at a 45 ° angle. Joints must be aligned with laths. To avoid shrinkage and swelling on the length, insert 4’, 6’, 8’ and 10’ planks between 12’, 14’ and 16’ planks. Never install two 12 ', 14’ or 16 ' planks end to end. Protect cuts with a UV-resistant sealer. Apply caulk around the windows, doors and where siding planks meet mouldings. Caulk must be applied in contact areas to the surface of the siding.

6) Alignment

A width variation of ±1/8" between the 6" planks is considered normal. Therefore, if a perfect horizontal alignment is required at the meeting point of two or more walls, you may have to plane the top edge of planks.

7) Mouldings

Nail your mouldings using 75 mm nails. Insert 2 nails every 16”, one on each side of the moulding, between 3/4”
and 1" from the edge.

8) Important Notice

Scratches and other minor damages occurring during installation will have to be sanded smooth by the installer.

All cuts must be protected with a UV-resistant sealer.

Failure to comply with the installation guide voids the warranty.

If the siding appears to be defective, immediately notify your retailer. Installation of defective material voids the warranty.
