What Makes a Sliding Glass Door Energy Efficient?
Insulated Glass
Most energy efficient sliding doors use double or triple glazing with gas-filled spaces (argon or krypton) to slow heat movement through the glass.
Low-E Coating
Low-emissivity (Low-E) coatings reflect infrared light, helping to retain heat during winter and block heat in summer.
Thermal Frames
Frames made from fiberglass, vinyl, or composite materials provide stronger insulation than standard aluminum.
Sealed Edges
Well-sealed door edges and high-quality weatherstripping prevent drafts and reduce energy loss.
