Aluma-Foil Radiant Barrier, 1000 Sq. Ft.

A Radiant Barrier is your best line of defense for keeping excess heat out of your attic in the summer or keeping your floors warm in the winter. Stapled under the rafters or joists, it reflects 97% of the radiant heat that strikes it. The non-profit Florida Solar Energy Center has shown that an attic radiant barrier can reduce air conditioning costs by at least 20%. Performance in drier climates is even better. This product is perforated, and won't become an unintentional moisture barrier. In order to function properly it must have an air space on at least one side. It doesn't matter if it's the hot or cold side. When the heat source is above the radiant heater it performs equivalent to R-14. This is a perforated, single-sided foil with a lightweight, tear-resistant paper/poly fiber backing that passes UL-723 flame spread fire tests. Supplied in 48" wide rolls at 125' (500 sq. ft.) or 250' (1000 sq. ft.) USA.
