ClimaGuard 80/70 delivers superior performance in cold, northern regions with significant heating requirements. It provides superior clarity and uses daylight’s natural beauty to:
Guardian Industries’ glass scientists and engineers designed ClimaGuard 80/70 to have a strong U-factor of .271 with argon, while maintaining a high solar heat gain. The result is a superior alternative to pyrolytic low-E glass that is neutral in color and attractive and optimized for heating-dominated climates.
ClimaGuard 80/70 offers excellent insulative properties and passive heat gain performance that:
ClimaGuard 80/70 is designed to have high solar heat gain and a low u-factor for northern climates. As shown below, it can be used in multiple configurations to meet the needs of many applications.
