Engineered Glass Products Earns UL® Approval
for Thermique Heated Architectural Windows
Glass Products (EGP) has announced that it has earned UL approval
for its new line of heated windows with Thermique technology
for residential and commercial buildings. Architectural windows
are among the first commercialized products designed with Thermique
heated glass, which EGP says was pioneered exclusively by its engineers.
As the first company to achieve UL approval for heating windows,
EGP is the only company approved to provide heated glass technology
for architectural use in the United States.
According to the company, Thermique windows radiate warmth
and comfort into a room, no matter how low the temperature drops
outside the building. Outdoors it may be well below freezing, but
the interior surface of the glass will remain above room temperature-up
to 105° F, depending on user settings. This is accomplished
with a transparent conductive oxide (TCO) coating and copper buss
bars that are applied to the glass during fabrication. The TCO coating
can be electrically heated with precise temperature control through
the use of a Thermique Hot Glass controller designed by EGP
specifically for the safe heating of Thermique Hot Glass. The glass
is always uniformly heated across the entire pane. It is never too
hot to touch so it is never a hazard, even with small children.
The controller is even able to sense a fault or a crack in the glass,
at which point it safely cuts off power.
Earning UL approval is critical for new electronic devices. Underwriters
Laboratories, Inc., issues UL approval based on its own independent
tests and standards. Underwriters Laboratories has developed more
than 800 "Standards for Safety," which are essential to
ensure public safety and instill confidence in new electronic products.
"With UL approval, architects, builders, and owners can be
confident that Thermique heated windows are a safe, responsible
choice," says Pete Gerhardinger, vice president of technology
at EGP. "Every new technology has to prove itself in independent
testing, and we're proud to have accomplished this important process
so quickly. The UL Listing is a testament to EGP's thorough development
and testing process, which ensures a safe and robust product for
While ordinary windows are typically the number one source of heat
loss in a building, Thermique windows contribute to the warmth
and comfort of a room. By electrically heating the glass, Thermique
technology eliminates the cold air pockets and drafts created by
traditional windows. Without these cold air problems, the building's
conventional HVAC equipment no longer has to work as hard to maintain
a stable indoor temperature. In fact, the thermostat can typically
be lowered with a noticeable improvement in comfort levels since
the windows are no longer cold nor drafty. This saves energy and
reduces wear-and-tear on traditional heating equipment. Plus, frost
and fog never form on a heated window; this makes Thermique
windows a great application for wet areas.
Engineered Glass Products previously earned UL approval for its
Thermique heated glass towel warmers for custom homes and
luxury hotels. The wall-mounted towel warmer uses technology similar
to the heated architectural windows.
Towels and other linens are simply draped across a stylish pane
of heated glass for luxurious comfort.
