Engineered for the Extreme Heat
Designed to function as a reflective thermos, the Unix Glass system keeps the temperature in your home more comfortable and consistent. Say goodbye to out of control temperature swings and hello to the level of comfort you have been waiting for.
The all-foam formula of Super Spacer blocks the heat path, so homes stay cool and comfortable inside.
The dual seal system helps Super Spacer insulating glass units last up to five times longer in durability tests than single-seal units.
The all-foam formula offsets the effects of temperature changes, baromatic pressure, window load, and glazing pressure. The end result is less seal failure and fewer stress cracks.
Installing ENERGY STAR® qualified windows lowers energy bills and saves you money over single-pane and even new double-paned, clear-glass windows. Windows with our high-performance glass package are ENERGY STAR® qualified for all regions.
