Ventilation
NewTechWood products CANNOT be directly installed onto a at surface. It must be installed onto a
substructure, so there is adequate and unobstructed air ow under the cladding to prevent excessive
water absorption. A minimum of 25 mm (1 inch) of continuous net free area under the cladding surface
is required for adequate ventilation on all cladding, so air can circulate between adjacent members to
promote drainage and drying.
Heat and Fire
Excessive heat on the surface of NewTechWood products from external sources such as but not limited
to re or reection of sunlight from energy efcient 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 reected 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 cladding 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. All fasteners should
be on their own independent joists, when two boards ends meet each other there must be a sister joist.
The end of each board must sit on its own joist.
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. Depending on the screws that you
use when face xing, there could be potential bulging or mushrooming. It is recommended to take care
of these mushrooms/bulges by taking a rubber mallet and patting them down to give your cladding a
better look.
When choosing which screws/nails to use always check rst with your local home centers and hardware
stores to see if they have screws that are engineered specically for composite wood. These screws/
nails will always work and give NewTechWood’s products the best looking outcome, using other screws/
nails that are not recommended for composite could potentially damage/harm the cladding. If you are
unsure which screw/nail to use, contact your manufacturer for more information.
