Window treatments were compared for their ability to reduce heat loss through a double-glazed window under subzero weather conditions. A full-sized window was used in a laboratory test system. Roller shades, roman shades, films, and other selected treatments were found to significantly reduced heat loss com pared to the bare window (p < 0.025). Heat loss was reduced to nearly half when roller shades and roman shades were sealed to the window frame. Draperies tested were not significantly different from the bare window. Unlike other re searchers (Hirning & Woell, 1978; U.S. Department of Energy, 1984), the covered cornice did not reduce heat loss, and combinations of window treatments did not improve effectiveness over a single treatment. A cost evaluation indicated that home-constructed roman shades and polystyrene boards would be cost ef fective and provide significant reduction of heat loss.
