What Is Low-E Door Glass?

Low-E glass, also known as low emissivity glass, is insulated glass treated with a microscopic coating designed to improve thermal performance by reflecting heat while still allowing natural light into the home.

Benefits Of Low-E Door Glass Inserts

• Improved energy efficiency
• Reduced heat transfer
• Better indoor temperature control
• Increased UV protection
• Reduced fading of flooring and furniture
• Improved comfort near entry doors
• Insulated tempered safety glass construction
• Modern replacement glass appearance

Many Low-E replacement glass inserts use dual-pane insulated glass systems for improved performance compared to standard single-pane glass.
