Low-E Glass helps to provide year round energy savings by controlling heat loss and heat gain in your home. Low-E Squared glass is coated with optically transparent layers of silver sandwiched between layers of anti-reflective metal oxide coatings. The smart coatings selectively filter the sun's heating energy in the summer and reduce heat loss in the winter.

During the summer months, the greatest potential for energy cost savings is the reduction of air conditioning costs. Low-E effectively filters out the solar energy that drives up summer cooling costs while blocking out 84% of harmful ultraviolet rays which damage curtains, carpeting and furniture. In the winter, Low-E reflects the room-side heat back into the room which helps reduce heating costs. Since the interior of the glass is warmer, the incidence of wintertime "sweating" or condensation associated with ordinary non-coated insulated glass windows is significant reduced.

Warm Edge Glass Technology

Warm edge insulated glass technology offers superior thermal performance and aesthetics and retains its performance over the years as a result of its innovative spacer system design.

Warm edge insulated glass technology centers around the automated fabrication of insulated glass unit spacers. The warm edge spacer is made from a thin steel strip, automatically formed into a one-piece glass spacer/structural support by computer operated machinery. Warm edge spacers provide excellent structural integrity and superior thermal performance in addition to being more aesthetically pleasing due to the low profile U-channel which is hidden from sight by the sash.

Warm Edge Technology Structural Advantage
With most competitive technologies, thermal cycling can weaken the sealant to glass and sealant to spacer bonds. As the glass expands and contracts, it can cause the spacer to "walk" out of its original position and lose its bond to the glass causing a seal failure. With warm edge insulated glass technology, however, thermal cycling stress is absorbed primarily by the steel spacer material rather than the sealant. The result is a high resistance to spacer migration and improved unit seal longevity.
