• ClimaGuard SPF alone does not have a significant impact on the energy efficiency of windows. ClimaGuard SPF is always paired with a Guardian low-E coating that provides energy saving benefits with the added benefit of blocking over 99% of UV light. Energy Star ratings are obtained by the window manufacturer for its complete window assembly. An integral part of how window manufacturers meet Energy Star requirements is based on the performance of the window glass. Guardian Industries has developed its residential window glass low-E coatings to help window manufacturers meet the requirements for Energy Star.
