Installation Guide

Ventilation
NewTechWood UltraShield CANNOT be directly installed onto a flat surface. It must be installed onto a substructure, so there is adequate and
unobstructed air flow under the deck to prevent excessive water absorption. A minimum of 6” of continuous net free area under the deck surface is
required for adequate ventilation on all decking so air can circulate between adjacent members to promote drainage and drying.
Heat and Fire
Excessive heat on the surface of NewTechWood UltraShield 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 UltraShield 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 UltraShield products to melt, sag, warp, discolor, increase expansion/contraction,
and accelerate weathering.
Current or potential NewTechWood UltraShield 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.
Fasteners
When fastening UltraShield 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 been down to UltraShield. An extra joist should be added if a 90 degree angle cannot be driven into the board.
Use white chalk, straight boards, or string lines as templates for straight lines. NEVER USE COLORED CHALK. Colored chalk will permanently stain
UltraShield and is highly not recommended.
Face fastening should follow the guidelines set out on page # of this installation guide. All nails/screws that are face fixed should always be stainless steel.
Depending on the screws that you use when face fixing 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 deck a better look.
When choosing which screws/nails to use always check first with your local home centers and hardware stores to see if they have screws that are
engineered specifically for composite decking. These screws/nails will always work and give UltraShield the best looking outcome, using other screws/nails
that are not recommended for composite could potentially damage/harm the deck. If you are unsure which screw/nail to use contact your manufacturer for
UltraShield
