The Challenge
Why This Product Exists
Buildings account for 40% of global energy consumption, with solar heat gain through glass being the primary driver of cooling costs. Standard clear glass transmits up to 84% of solar energy, creating uncomfortable interiors and unsustainable energy bills that escalate year after year.

Common Questions
Frequently Asked Questions
Single silver offers basic solar control with high light transmission. Double silver provides enhanced solar rejection while maintaining good visibility. Triple silver delivers maximum solar control (SHGC as low as 0.17) for extreme climates, with slightly reduced visible light.
Yes. Our Low-E coatings are designed to withstand tempering and laminating processes. The coating is applied before heat treatment, ensuring durability and performance integrity.
Modern magnetron-sputtered Low-E coatings are virtually color-neutral. Unlike older pyrolytic coatings, our soft-coat Low-E maintains a clear, natural appearance from both interior and exterior.
Depending on climate and configuration, Low-E glass can reduce cooling costs by 25-40% compared to standard clear glass. In hot climates, triple silver Low-E combined with insulated units can achieve energy savings of up to 50%.
We provide a 10-year warranty on all Low-E coatings against delamination, hazing, or performance degradation when used in properly sealed insulated glass units.
