- Energy-efficient glass : Energy-efficient glass has a low emissivity surface which reflects heat radiation. Depending on its position in the glazing, it will keep the heat inside the house or prevent it from entering.
- Spacer : We use the intercept® spacer in its double glazing doorglass. This “warm edge” spacer type, combined with energy-efficient glass and argon gas, reduces condensation on the periphery of the glass in winter.
- Argon : The argon gas in your glazing reduces heat transfer by convection and improves energy efficiency.
- Frame : Frame size varies according to glass size.
- Insulated glass size: 22×64”, 22×48”, 22×36”
- Insulated glass thickness : 1”
