• DO NOT use nails to fasten I-Series boards�
• Use high quality HULK fasteners suitable for the life span of
the deck and the atmospheric conditions of the site.
• I-Series boards require two fasteners points per joist.
• Fasten 1-1/4" [32mm] from any edge of a board�
• A drill with adjustable torque settings is recommended.
• Pre-drill in temperatures below 40°F [5°C] .
• Pre-drilling hole size should be equal to the smallest
diameter of the screw�
• Reference fastener manufacturer for pre-drill bit size.
• DO NOT pre-drill wood substructure.
Board Application
• The installation of I-Series boards is comparable to that of
other composite or decking boards.
• I-Series profiles ARE NOT intended for use as structural
members�
• The surface overhang of the deck must be limited to a
maximum of 1-1/4" [32mm] and take into consideration
the thickness of the Fascia or trim�
• Reflective surfaces (for example, low-E glass or metallic
siding) may cause unusual UV impact and/or heat
build-up on a deck, which may cause unexpected results
in the I-Series material� Design your deck to allow
for this where possible.
• Provide ground clearance for adequate ventilation.
Ventilation can have the added benefit of assisting
with expansion and contraction. As shown in Fig. 1.

A 1-1/2" [38mm] gap beneath the deck
is required for additional ventilation.

A Properly ventilated deck

DECKING INSTALLATION : I-SERIES
Gaps between deck boards
assist with ventilation
Condensation & Evaporation
occur naturally. Sealing off a
deck may therefore cause a
constantly wet environment
that may harm the
substructure beneath, which
in the long term could
harm your deck�
