Installation & Assembly

Decking Installation Guide / v20191125US 3
(www.aclstaticide.com) on your deck or use anti-static mats before doorways. NewTechWood’s products
have been tested against EN 1815 - Assessment of Static Electrical Propensity and have received values
under the maximum standard of 2kV.
Ventilation
NewTechWood products CANNOT be directly installed onto a at surface. It must be installed onto a
substructure that is made into a frame, so there is adequate and unobstructed air flow under the
decking to prevent excessive water absorption. If there is excessive water absorption to any area that
does not have the protection of the cap layer, there could be some swelling that occurs. A minimum
of 4 inches of continuous net free area under the decking surface is required for adequate ventilation
on all decking, so air can circulate between adjacent members to promote drainage and drying. In the
case that installation is below 4 inches, it is recommended to look up the maximum rainfall of the area
to determine what height would need to built to ensure no ooding of the deck occurs. If the rainfall is
determined not to ood the deck, a slope of 1-2% must be used on the frame towards the direction of
the drainage to ensure that there is no free standing water. If the deck is built below 4 inches without a
slope, the areas without the protection of the cap layer could swell on the ends.
Heat and Fire
Excessive heat on the surface of NewTechWood products from external sources such as but not limited
to re or reection of sunlight from energy efcient window products. Low-emissivity (Low-E) glass can
potentially harm NewTechWood products. Low-E glass is designed to prevent passive heat gain within a
structure and can cause unusual heat build-up on exterior surfaces. This extreme elevation of surface
temperatures, which exceeds that of normal exposure, can possibly cause NewTechWood products to
melt, sag, warp, discolor, increase expansion/contraction, and accelerate weathering.
Current or potential NewTechWood customers that have concerns about possible damage by Low-E
glass should contact the manufacturer of the product which contains Low-E glass for a solution to
reduce or eliminate the effects of reected sunlight.
Fasteners
When fastening NewTechWood’s products, all screws that are face fastened should always be driven in
at a 90 degree angle to the decking surface. Toe nailing/screwing should never be done to the products.
An extra joist should be added if a 90 degree angle cannot be driven into the board as shown in Diagram 1.
All fasteners should be on their own independent joists, when two boards ends meet each other there
must be a sister joist with a minimum of 5 mm between the sister joists for water to go down between
the joists. Excessive build of water over long periods of time at the ends could result in swelling. The end
of each board must sit on its own joist as shown in Diagram 2.
Use white chalk, straight boards, or string lines as templates for straight lines. NEVER USE COLORED
CHALK. Colored chalk will permanently stain NewTechWood’s products and are highly not recommended.
All nails/screws that are face xed should always be stainless steel. When face xing, always go in at
least from the ends and width of the board by 1”1/2 as shown in Diagram 3.
