DECKING
For maximum protection, opt for
an ‘above-the-joist’ system with
poly or rubberized membranes
that drape over the joists to ensure
that the joists and beams of the
substructure are shielded from
moisture penetration. This type of
system also helps to hold screws
in place longer and acts as a shield
between galvanized metal and
timber. Furthermore, the membrane
material (vs. metal, vinyl or PVC)
accommodates a broader range of
ceiling options for homeowners
seeking a finished aesthetic.
Systems that install below the joists
leave timber and metal exposed to
the elements and more susceptible
to water damage and corrosion.
This type of system can trap

moisture in the core supports of the
substructure. In warmer months,
rising temperatures ‘cook’ the
trapped, wet wood and accelerate
rotting. Over time, this combination
of moisture, heat and lack of
ventilation can create a potentially
dangerous formula for deterioration.
Once protected, the dry space
beneath a deck can be used for
storage or as additional living space.
Homeowners can add electricity,
water and gas lines, as well as
furniture, lighting, ceiling fans
and entertainment components,
depending on how they plan to use
their new-found space.
The possibilities are limitless,
and the process is simple. Trex®
RainEscape®, for instance, is a high
quality, affordable, above-the-joist
deck drainage system that can be
installed using just a stapler, utility
knife and caulk. Each trough is
clearly labeled with staple markers
to expedite the process, which
takes no more than a few hours to
complete. And, the system is backed
by a 20-year warranty from the
world’s #1 decking brand.
Both of these upgrades add
considerable function and value to a
deck project without adding a lot of
time or cost.
