Founded in Minneapolis, Minnesota by M.L. Gordon.
Introduced triple-pane insulating glass for energy savings.
Began use of silicone dual-seal insulating glass for improved durability.
Introduced LoĒ™ coatings to produce triple-pane performance in dual-pane construction.
Built dedicated factory to supply LoĒ coatings for residential windows.
Introduced argon gas filling of insulating glass units: combined with LoĒ this provides “quad-pane” performance in a dual pane IG unit.
Introduced LoĒ2 ® coatings for year-round energy performance.
Built first float glass plant to stabilize a glass supply chain for IG and CG plants.
Launched XL Edge® glass, a durable, warm edge IG spacer system.
Introduction of easier-to-clean LoĒ2 Plus® glass – built for the busy lifestyle.
Preserve® film application launched. Protects windows through the entire construction process.
Neat® glass introduced, the next generation of easier-to-clean glazing.
LoĒ3-366®. The next generation of low-E: triple silver for low U-factor, low solar heat gain, and high light transmission.
LoĒ-i81®. A durable low-E coating that can be used in exposed applications without the haze attributable to most “hard-coat” products.
LoĒ-180. High solar gain low-E, re-engineered. The highest light transmission and lowest U-factor of any passive solar glazing.
LoĒ-i89®. Energy-saving 4th surface coated glass. It offers more light transmittance and less reflectance than the i81 product.
Endur™ IG. Exceptional longevity and warm edge performance. Delivers the industry’s lowest failure rate with the only comprehensive 20-year factory warranty.
