Product Overview
Low-e tempered glass door uses low-emissivity coated insulated glass in aluminum frames to keep heat out in summer and in during winter — measurable energy savings on glass-heavy facades.
The low-E coating reflects infrared while transmitting light, cutting solar gain by up to 60% versus clear glazing. Paired with thermal break frames, it meets modern energy codes for residential and commercial doors.
