If you have a triangular or similar asymetrical (not rectangular or square) window on your house--a not uncommon situation with contemporary homes with clerestory windows--and you are seeking an effective form of sun control, you are in luck.
Intertrade Inc., 3175 Fujita St., Torrance, first mentioned in this column about four years ago, is marketing the Asyroll, a West German roll shutter that reportedly is the first to be designed specifically for asymetrical windows. Roll shutters have long been used in Europe for the selective insulation of windows and are increasingly used in this country.
Roll shutters are designed so they can be lowered during the hottest part of the day, to keep heat from entering the home while still permitting light to enter through specially designed slits in the shutter slats. If you want more light, the slats can be supplied in translucent plastic, according to Arno I. Zwarg, president of Intertrade.
Also new from Intertrade are retractable patio awnings with hardware in colors as well as the standard anodized aluminum color that is supplied for more than 90% of the awnings sold, he added. The colors, available at extra cost, are: green, dark brown, blue, beige and off-white.
