Thermal Wrap & Attic Wrap™
DuPont™ Tyvek® HomeWrap™ makes your home more comfortable
to live in and your energy bills
easier to live with. It prevents
heated or air conditioned air
from escaping through the cracks
and seams in the wall cavity.
It allows you better control
over the interior climate and
protects the R-value of your
insulation while serving as a
secondary water barrier.
DuPont™ Tyvek® ThermaWrap™ helps regulate the radiant energy
of wall systems for increased
comfort and reduced energy costs.
In the winter, DuPont™ Tyvek® ThermaWrap™ helps keep radiant energy that
accumulates in the wall sheathing
from releasing to the exterior.
In the summer, the metalized
surface reflects radiant heat
out of the wall, helping to keep
the interior cooler. Reducing
radiant heat flow through the
wall system is particularly important
at the studs, plate lines, joists
and headers where conductive
heat flow through the wall is
the greatest. This not only saves
energy and reduces heating and
cooling costs, it also changes
the dew point in the wall to
help reduce the risk of condensation
which can lead to mildew, mold,
and wood rot in wall cavities.
This is especially important
to keep in mind in hot, humid
climates where foil-faces sheathing
and other radiant barriers are
often installed on the exterior
to reflect heat away from homes.
DuPont™ Tyvek® AtticWrap™ is a revolutionary
breathable membrane that helps
create an airtight seal to reduce
air leakage and energy loss through
the roof. With a unique, metalized
surface that reflects heat and
a breathable structure to protect
against the damaging effects
of moisture build-up, it helps
keep attics warmer in the winter,
cooler in the summer, and drier
all year round. An airtight attic
seals in warm air during the
winter, increasing the overall
performance of attic insulation.
In the summer, an airtight attic
stays cooler because the cooling
ventilation air circulates directly
beneath the roof sheathing, while
the unique metalized surface
reflects heat away from the attic.
The result is a semi-conditioned
attic space suitable for storage
without concern of contamination.
And because Tyvek AtticWrap™ creates
an airtight attic, conditioned
interior air is less likely to
leak through the ceiling from
the living space and into the
attic. Tyvek AtticWrap™ also collects
leaking water and channels it
to the eaves where it can safely
drain outside the home.
DuPont™ Flashing System provides comprehensive
protection from water leaks.
There are many ways that water
can find its way into a window
or window opening. A window will
not perform to a builder or homeowner’s
expectations if it is not properly
flashed. DuPont™ Flashing System
is designed to help direct water
to the building exterior instead
of trapping it inside the wall
system and causing water damage.
