Q. What is High Performance LoE2 Glass?

High Performance LoE2 glass products from The Window Factory give you year-round energy savings and comfort by helping manage the sun's energy and the heating system energy in your home.

High Performance LoE2 glass products from The Window Factory are coated with microscopically thin, optically transparent layers of silver sandwiched between layers of antireflective metal oxide coatings.

These "smart" coatings provide optimal year-round energy saving benefits by selectively filtering the sun's energy in summer and reducing heat loss in winter. In the summer, High Performance LoE2 glass products from The Window Factory let in visible sunlight while blocking infrared and ultraviolet solar energy that drives up cooling costs and damages curtains, window treatments, carpeting and furnishings. And in the winter, High Performance LoE2 glass products from The Window Factory offer greater comfort and reduced heating costs by reflecting room-side heat back into the room.
