Duraseal® Warm-edge Spacer
Regardless of the season, home comfort begins with
windows built with Duraseal®.
On a cold, wintry day, the inside glass surface of
an inefficient window will draw heat from your
body leaving you feeling chilly inside your home.
Windows built with Duraseal reduce heat transfer
and improve the temperature of your inside
window glass.

Duraseal® Spacer Design
Duraseal is a flexible, warm-edge spacer featuring a
unique composite laminating technology that provides
superior durability and thermal performance
in insulating glass units.
To achieve the ultimate in performance – all in a singleseal design – Duraseal is preassembled with an air-filled
shim, butyl sealant, a three-sided continuous moisture
barrier and a desiccated topcoat. The results are better
performance now, and in the future.

Reduce Condensation for a Clear View
Windows that are poorly insulated allow moisture to
collect in the form of condensation. Condensation can
obstruct your outside view, reduce natural lighting and
damage interior finishes. Moisture and condensation
can also increase the risk of mold.
Windows built with Duraseal warm-edge spacers
reduce condensation, keeping moisture off your glass
for a clearer view to the outside.

Superior Thermal Performance
The thermal performance of a window plays a major role
in household energy conservation. A high-performance
window system will keep your energy costs low by
reducing heat loss in the winter and heat gain in the
summer.
Duraseal combined with Low-E glass and argon produces
one of the highest performing, energy-efficient window
systems, saving you money on your heating and cooling
costs. Duraseal is an ENERGY STAR® qualified product.

Argon Permeability
Duraseal has one of the best argon resistant bondline
adhesives to retain argon in your window longer
and save more energy. This is vital to the window
maintaining its thermal performance from day one – to
many years down the road.

Durable and Long Lasting
Windows built with Duraseal will stand up to the most
severe weather conditions in both hot and cold climates.
The Duraseal warm-edge spacer is designed to last
for years, delivering durability and high performance
to homeowners. To ensure your window investment
is secure for many years to come, choose worry-free
windows built with Duraseal.

Enhance Your Comfort
When it comes to windows, you have many choices in
colors, interior finishes, hardware and glass. Most glass
options also have a variety of different spacer choices
that can make a real difference in performance and
comfort.
The warmer the glass edge, the less energy lost and the
more comfortable you feel near your window.

Be Worry Free
The Duraseal® spacer is a composite laminate
design that optimizes the use of a number of spacer
components that help ensure argon retention and
moisture prevention. All spacers need adhesives,
sealants, structural elements and desiccant to perform.

They also need to last a long time under adverse
conditions inside your window frame. Duraseal is
designed to seal your window better and longer, while
increasing energy savings compared to other types of
spacers.

Look for Duraseal high-performance
spacer in your windows and doors.
