When the sun is shining, ClimaGuard 70/36 regulates heat inside.
ClimaGuard 70/36 is designed to keep interior temperatures comfortable when the sun is
shining and solar heat gain is a concern. Homeowners can maximize daylight and enjoy the
view while keeping air conditioning costs to a minimum.
Keep the view while losing the heat
Sunshine is beautiful but adds heat to a home. This is especially true with east-, south- or
west-facing windows. Dark window tints, window films, exterior solar screens, landscaping,
and room-darkening blinds and drapes can block the sun, but they also block the view. With
ClimaGuard 70/36, homeowners can maintain or even expand their “window on the world”
without sacrificing interior comfort or spending a fortune on air conditioning.
“70/36” means more light with less heat
The numbers are impressive. “70” indicates that 70% of the sun’s visible light shines through
the glass. “36” indicates that only 36% of the sun’s heat makes its way through (the other 64%
is blocked). That means plenty of sunshine can add beauty to a home without adding too
much heat.
Maintain comfort in cold weather, too
In addition to providing relief from the intense heat of the sun, ClimaGuard 70/36 also provides
superior insulating performance to help save energy and maintain comfort during cold winter
nights by efficiently reflecting the heat of a home’s furnace back into the house.
