Installation Guide

Heat and Fire
Excessive heat on the surface of NewTechWood
products from external sources such as but not
limited to fire or reflection of sunlight from energy
efficient 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 reflected sunlight.
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 fixed should always be
stainless steel. When face fixing always go in at least
from the ends and width of the board by 1”1/2 as shown
in Diagram 3.

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.
