Tempered glass Tempered glass consists of tempered safety glass triple-coated with LoE3, dual-sealed and injected with Argon gas. This quality glass provides excellent energy efficiency, thermal performance and protects against the sun's fade causing rays. Tempered glass can also be combined with other energy efficient options for even greater performance.

Benefits
  • High energy efficiency results in a more comfortable living environment and money savings on utility bills.
  • NFRC rating is substantially better than required by most common building codes.
  • Provides three times more protection against solar heat gain.
  • Resists condensation twice as long as clear glass.
  • Protects interior spaces by reflecting the vast majority of the sun's fade causing rays.
Features
Tempered glass is LoE3, argon gas-filled glass designed for maximum energy efficiency.
