Although all types look similar on the rolls or in the kits, there are differences in their heat and glare reduction properties. These use multilayer polyester film with a special invisible heat-reflecting coating on the inner layers. For smaller windows, a standard spring roll shade works well. For the most convenience, select motorized shades with hand-held remote controls or automatic sun sensors to open and close them. Special heavy, close-weave window screening is a third option and allows for ventilation with sun control.
Kits are available for easy installation.
Update Bulletin No. We have one room that does not stay cool enough in the afternoon. Using it will eliminate the need to set the central thermostat lower just to cool that one room adequately. If you have several rooms that do not cool properly, usually in the same area of the house, consider adding a zoned cooling system with duct dampers.
