Get the Best Protection Under the Sun.
No other glass technology gives you this much.
If home furnishings could talk, they'd tell you that the sun's punishing UV rays can prematurely fade expensive wood floors, curtains, rugs and cherished mementos. But now there's ClimaGuard SPF, offering complete UV protection and plenty of natural daylight. ClimaGuard SPF blocks what you don't want while maximizing what you do want - the natural light that brightens your home and mood.
Even the highest performing low-E products come up short on UV protection. Typical low-E glass blocks only 75-85% of harmful UV rays. the remaining UV light - up to 25 percent - still reaches wood floors and home furnishings, causing considerable fading and damage.
ClimaGuard SPF Performance
ClimaGuard SPF provides UV protection with an FPF rating of 50+ and can be used in conjunction with many ClimaGuard low-E products to meet the needs of various climates and applications.
