Southwall teams with Pleotint to create adaptable IG

September 30, 2011  By Southwall Technologies

Sep 30, 2011- Southwall Technologies and Pleotint have announced their first installation of high-performance insulating glass that combines Southwall's Heat Mirror suspended-film technology with Pleotint's Sunlight Responsive Thermochromic technology.
The complementary technologies are combined to deliver increased energy
savings by reducing solar heat gain and glare during peak electrical
usage hours, providing optimal daylighting during non-peak hours, while
delivering maximum thermal insulation 24 hours a day.

The product was manufactured by Southwall Insulating Glass
and installed at Pleotint's corporate headquarters in West Olive,
Mi. The combined solution provides superior centre-of-glass
insulating performance of 0.13 (R8) with Argon gas fill. In addition,
visible light transmission and solar heat gain coefficient adaptively vary based on sun exposure from 44 per cent to below 10
per cent and from 28 per cent down to 12 per cent, respectively. While not
part of the initial product configuration, options such as a second Heat
Mirror film, Krypton gas, or both, could be used to further improve
center of glass insulating performance below 0.10 (R10).

"Southwall is a true innovator in energy-saving films and glass, and
we are proud to work with it to provide the industry with such a high
performance insulating glass solution," said Harlan Byker, CEO of
Pleotint. "We have had the opportunity to see and feel the effects of
the solution first-hand in our headquarters. The heat gain from the sun
is gone, you can't feel it."


"Dynamic heat gain management and high thermal insulation are
complementary solutions," said Dennis Capovilla, CEO of Southwall. "We are excited about our work with Pleotint to combine
two technologies and deliver a complete glazing
