A Window Designer - Custom crafted and ready made window blinds, shades,and coverings. Our Roman Shades provide a degree of insulation. Thicker fabrics will insulate better than sheerer fabrics.
Liners also add to the insulation value.
There are, however, no specific R-factors for Roman Shades. Use your vacuum cleaner's brush attachment and gently go over the shade. Doing this at least once a month will prevent dust accumulation. We recommend using professional cleaners to remove stains and mold. Standard lining filters light, while blackout lining blocks out light.
