Will Curtains Reduce Heat

The ability of curtains and drapes to reduce heat gain depends on the fabric type (closed or open weave) and color. Studies have found that medium-colored draperies with white plastic backings can reduce heat gain by 33 percent, the DOE says. Hang the curtains as close to windows as possible.
