Installation Guide
As with any building project, installing Style Selections composite
decking turns out best when you think through the entire process
in advance, familiarizing yourself with the materials and their application.
Please review the following tips before starting work on a Style
Selections composite deck. Color variation is a distinct feature of
Style Selections composite decking. Each board has a unique
appearance and should be arranged according to the end user’s
preference. Prior to construction, check with your local regulatory
agency for special code requirements in your area. For best results,
follow these simple installation instructions, paying close attention
to gapping, spacing and fastener requirements.
Joist Span
16 in on-center for residential perpendicular applications. Residential
parquet patterns, diagonal or herringbone designs all require joist
spacing 12 in on-center.
Side Gapping – 1/4 in.
End-to-End Spacing
Allow a minimum of 1/16 in gap between board ends for every
20°F of difference between installation temperature and the hottest
temperature expected (see Figure 1). Additional blocking may be
needed for support (see Figure 2). Allow 1/4 in distance between all
decking material and any permanent structure or post. After all
of the decking has been attached, snap a chalk line (white or yellow
chalk recommended), ush with or up to 1-1/2 in out from the deck
framing, and trim with a circular saw. Style Selections, like all wood
and composite decking products, requires proper ventilation and
drainage in order to ensure its longevity. When using a minimum
2 ft x6 ft joist standing on edge and the suggested 1/4 in side gap,
there should be a 2 in clear space between the bottom edge of
the joists and grade in order to allow for proper ventilation. Adequate
drainage is also needed to prevent water from pooling under the deck.
Fasteners
For ease of installation, we recommend using a hidden fastener that
fits into the inch slot on each side of the deck board to eliminate pre-
drilling and provide a timeless, fastener-free deck surface. The deck
boards require traditional fasteners on the outside and inside edges of
the deck. Begin by fastening the outside edge of the first board to the
rim joist every 16 in. For this, we recommend using 2-1/2 in corrosion
resistant, composite wood deck screws. These screws help minimize
the common “mushroom” effect that sometimes occurs when using
standard fasteners. It can also reduce the amount of pre-drilling and
countersinking. If using ordinary coarse-thread deck screws, always
pre-drill a pilot hole and countersink prior to driving screws. Screws
should be driven flush with the surface. Do not over-tighten. Use one
fastener per board every 16 in. For any decking where two boards
meet end-to-end over a joist, add additional blocking. Always pre-drill
a pilot hole when fastening within 1-1/2 in of board ends, whether
using composite or wood screws. Do not over-tighten screws at board
ends. Fasten the outside edge of the rst board to the rim joist with
screws. Pre-drill and countersink all deck screws, regardless of type,
that are within 1-1/2 in of the end of the deck board. Follow the
instructions from the fastener manufacturer to install hidden fasten-
ers in Style Selections composite decking. Apply these same principles
when installing stair treads.
Fascia
Attach fascia to the rim joist using two screws spaced no further
apart than 16 in on-center. Fasten the fascia from one end to the
other or from the center out to each end. Never fasten the fascia from
both ends to the center. Leave a 1/8 in space between the fascia ends
where two pieces meet or wherever a piece meets a solid surface
(i.e., a corner or a building wall) to allow for expansion of the material.
Installation Instructions
Pre-drill and countersink all
deck screws, regardless of type,
that are within 1-1/2 in of the
end of the deck board.
