Features of the Best Windows for Energy Efficiency
Double or Triple Glazing
Windows with double or triple glazing have multiple panes of glass. These layers trap air between the panes, creating insulation.
Low-E Glass
Low-emissivity (Low-E) glass has a special coating that reflects heat. It keeps warmth inside during winter and outside during summer.
Gas Fills
Many energy-efficient windows have argon or krypton gas between the panes. These gases provide better insulation than air.
Tight Seals
Well-sealed windows prevent air leaks, keeping your home comfortable and saving energy.
