IMPORTANT Note: 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 siding 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.
Static Static can also be more prevalent in areas that are of higher altitude because the humidity is lower. For these areas, be careful of using conducive objects such as metal railing and chairs as static shocks might occur more often. A potential way to lower the amount of static shocks occurring is to apply Staticide (www.aclstaticide.com) on your deck or use anti-static mats before doorways. Ventilation NewTechWood products CANNOT be directly installed onto a flat surface.
Predrill It is recommended to use the #8 pan head screw for face fixing the profiles and the trims onto the furring strips. When face fixing, it is recommended to predrill the holes slightly larger on the profiles and the trims to allow for expansion and contraction response to temperature change, as shown in below diagram, The predrilled hole size should be larger than the screw thread size, from 1/16” (1.5 mm) to 5 /64” (2 mm).

European Siding Screws (For Wood Furring Strip) The table below shows the screws recommended to use for the installation, but not included.
European Siding Screws (For Aluminum Furring Strip) The table below shows the screws recommended to use for the installation, but not included.
Under Construction We recommend for the under construction aluminum or pressure treated wood furring strips. Each siding board needs to be supported by a furring strip NO MORE than 16" (406mm) 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.
Furring Strips 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 furring strips. The furring strip needs to have a minimum thickness of 1" (25mm). Wood furring strips should be fixed into position at a maximum of 16" (406mm) 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 Since the composite wood must allow for expansion and contraction due to temperature change, the board must be locked at one fixed point but only one point to allow the remaining board to expand and contract freely. In the case there is a need to lock the board, Clip (AW08) comes with a separate hole. It is important that DO NOT LOCK any other clips for the same board.

European Siding System Horizontal Installation Installation Procedure Step 1: Framing - Measure and Chalk the joists - Furring Strips Installation Step 2: Trim Installation Step 3: Siding Board Installation - Installing the First course - Installing the Second course - Continuing the remaining installation - Installing the Last board Step 4: Finish the Top 1 Framing The frame needs to be level before installing the siding boards.
2 Measure and chalk the furring strips according to the span data specified on page 10 of this installation guide, as shown in Diagram 2 . 3 Fix the furring strips onto the wall that you intend to install with screws at least 19 5/8” (500mm) and max to 39 3/8” (1000mm) on center, as shown in Diagram 3 . Detail 3-3 Detail 3-4 Min 19 5/8" (500mm) Max 39 3/8" (1000mm) Detail 3-2 Detail 3-1 Diagram 2 Diagram 3 Note: Note: 1. We are using wood furring strips for this installation.
1 1/8" (28mm) 4 1 3/4" (45mm) Wall Furring Strip Trim Installation Secure the F-Trim (UH50) onto the wall outermost edge joist and the Outside Corner Trim (UH51) onto the wall outside corner joist with screws at least 19 5/8" (500mm) and max to 39 3/8" (1000mm) on center, respectively, as shown in Diagram 4 .
5 Install the Starting Trim (AW02) at the end of the joists opposite the floor with screws, as shown in Diagram 5 . Furring Strip Wall Starting Trim (AW02) min 3/16" (5mm) F-Trim (US73) Detail 5-2 Detail 5-1 Starting Trim (AW02) Min 7/16" (11mm) Diagram 5 Note: 1. Outermost Edge A minimum gap of 3/16" (5mm) needs to be left between the Starting Trim (AW02) and the F-Trim (UH50), as shown in Detail 5-1 and 5-2 . 2.
Note: Fasten the Starting Trim (AW02) with a clearance of 1 3/4" (45mm) above the floor, as shown in Detail 5-4 . Furring Strip Siding Board Installation Installing the First course Put the first European Siding Board (UH46) over the Starting Trim (AW02) and fasten it onto the furring strip with Clip (AW08), as shown in Diagram 6 and Detail 6-1 .
Note: Since the composite wood must allow for expansion and contraction due to temperature change, the board must be locked at one fixed point but only one point to allow the remaining board to move freely. When installing horizontally, it is required to lock the Clip (AW08) at the middle of each board, as shown in Detail 6-2 . DO NOT LOCK any other Clips (AW08) for the same board. Please review page 13 , "Locking the Siding Board" of this installation guide for further information.
