DECKING
There are two primary options
when it comes to deck flashing
tapes – asphalt-based and butyl
tape. Although asphalt-based tape
is generally less expensive, it tends
to dry out more quickly, curl up and
hold water. Butyl tape offers several
advantages over asphalt-based tape.
It is stickier, performs better in a
wider range of temperatures and
is more pliable, which allows it to
create a tighter seal around screws
to prevent water from infiltrating
screw holes.
Trex® Protect™ is a popular self-
adhesive butyl tape that works on
horizontal and vertical surfaces and
is applied as a “cap” (vs. wrapping),
which allows the wood to breathe.
The tape lies directly on the boards
and features a non-skid surface,
making it safer for contractors to
walk across during construction. The
peel-and-stick application is simple
and requires almost no trimming.
For added confidence and peace
of mind, Trex Protect is the only
tape on the market that comes with
a 20-year warranty, ensuring the
substructure will last as long as the
decking it supports.
Optimize Space Beneath an
Elevated Deck
Outdoor space and ample storage
are among the most sought-after
amenities by today’s homeowners
and prospective homebuyers. In
both cases, the area beneath an
elevated deck can offer an ideal
solution. With the addition of an
under-deck drainage system, this
space can become usable for a
multitude of purposes.
Using a network of troughs and
downspouts, a deck drainage
system captures and diverts water
away from a deck to protect the
substructure from moisture and
create dry space underneath. But
it’s important to keep in mind that
all drainage systems are not created
equal.
