IMPORTANT: Read All Sections Before You Start For the most up to date information, please visit our website @ www.newtechwood.com Prior to installing any composite cladding system, it is recommended that you check with local building codes for any special requirements or restrictions. The diagrams and instructions outlined in this guide are for illustration purposes only and are not meant or implied to replace a licensed professional.

It must be installed onto a substructure, so there is adequate and unobstructed air flow under the cladding to prevent excessive water absorption.
Siding Parts Product Purpose AW-02 Used for the installation of the first board AW-08 Used at every joist to fix each board to the joist T-7 Used on the last Siding board US09 Siding Board (can be used in place of US30, US31) US44 Part F-Trim, used at the windows US45 I-Trim, used if there is a break between two boards to cover up the gap US46 Outside Corner Trim, used on the outside corners US47 Inside Corner Trim, used on the inside corners Siding Installation Guide / v20190507US 4
Siding Screws Product Purpose *M3 x 12 SS304 Used when locking the board and installing into wood joists *M4 x 13 SS410 Used when locking the board, installing into metal joists, and installing AW-08 *M4 x 80** SS304 **depends on the thickness of your joists Used to install the joist to the wall Part *Note: All screws are based on our recommendation and if the installation requires something different than what is shown, a professional should be consulted before installing.
Under Construction We recommend for the under construction aluminum or pressure treated wood joists. Each cladding board needs to be supported by a joist NO MORE than 1.64 feet (500 mm) from center to center. Extra care is required in order to provide sufficient joisting in and around obstacles such as windows, fascia’s, soffits, guttering, ventilation points etc.
Joist Installation A building professional should be consulted regarding vapor barriers and insulation for your project. Where a vapor barrier is to be used, it should be a breathable type and must be positioned behind the joists. The joist needs to have a minimum thickness of 1 inch (25 mm). Wood joists should be fixed into position at a maximum of 1.64 feet (500 mm) centers using a suitable A4 Stainless Steel Countersunk Wood/Masonry screw.
Expansion and Contraction Values NewTechWood siding boards will experience expansion and contraction with changes in temperature. Expansion and contraction are most significant where extreme temperature changes occur. Fastening the deck planks according to the gapping requirements noted in the following table accommodates for this movement.

Locking the Siding Board Every AW-08 clip comes with a separate hole in the case there is a need to lock the board. The Siding boards will expand and contract and to take care of this movement, we must lock the board in one position and then allow the board to expand and contract readily in the other direction. You can see how we lock the board in Diagram 1, 2, and 3. Note: DO NOT LOCK EVERY BOARD. General rule of thumb is every board will only need one locking/ fixation point.
Framing The frame needs to be completely level before installing any Siding boards. Note: Adequate spacing in the joists is required to keep the cladding boards from bending. Please review page 6 of this installation guide to see what spacing is required. The wall as shown in Diagram 4 will be installed to replicate different scenarios potentially occurring when installing the Siding. DIAGRAM 6 DIAGRAM 4 1 First start by fixing the joist onto the wall you plan to install on.
Option 1: Installing the Trims and then Boards Inside Corner Trim 1 The inside corner will be installed as shown in Diagram 8 by first pre drilling and then fixing with screws. DIAGRAM 9 Starting Strip 1 The starting strip will now be installed on the bottom of the joists as shown in Diagram 10 by first pre drilling into the AW-02 and then fixing with screws. 2 Repeat step 1 and install the rest of the starting strip onto the rest of the joists.
Siding Board 1 3 Take a Siding board and place the side with the lip down as shown in Diagram 11. When you are on the last board of the Siding you will need to first install T-7. The T-7 will be installed onto every joist first and then the Siding board will be installed like normal as shown in Diagram 13. Note: The T-7 is used as a place holder for the last board, so that the board will not slant. DIAGRAM 11 2 Place the AW-08 on the board and install with screws as shown in Diagram 12.
