Technical Details

  • Energy-efficient windows are created by putting sheets of glass together with spacers. These multi-layers have air pockets between the panes, which are sealed shut and prevent air from entering or escaping
  • Once this is complete, the windows are filled with argon, krypton, and other gases, all of which are non-toxic, odorless, and colorless to increase their efficiency
