Although solar screens typically cost more than traditional blinds, they will help homeowners save money in other ways. Screens keep in heat and cool better and help lower energy costs by decreasing use of air conditioning systems or fans. Solar screens also help homeowners save money on replacing furniture that is damaged or faded from the sun.
One of the primary economic benefits of choosing traditional blinds is that they generally cost less than solar screens. Window blinds vary in price, depending on the blinds' material and size. Solar screens can cost over $100 per screen. Some window blinds are equipped with black out liners or do not have cords to avoid holes for the slats. This material prevents sunlight from seeping in, although it may not be as effective as solar screens.
