Save Money
Interior shades (drapes, blinds, and the like) can reflect light energy back out that would otherwise be converted to heat energy inside the home. Window shades can reduce the solar heat gain coefficient of clear glass from 20 to 70 percent. That's a pretty big range. Controlling the heat gain temperature with window shades, will decrease the intensive use of cooling and heating systems, and will save money on potential appliance repairs consequently lowering electrical and gas costs.
