Replacing your windows is the single-most effective way to reduce energy costs in your home. But, not all new windows will perform to your expectations. By choosing windows with an IntelliGlass high-performance glazing system, you ensure energy savings for you and your home.

ClimaGuard SPF can be added to all IntelliGlass high-performance glass packages. ClimaGuard SPF is the first glass technology to provide complete protection against harmful UV rays.
ClimaGuard SPF blocks 99.9% of both UV-A and UV-B radiation.
