Interior Window Shades and Shutters

Interior Window Shades and Shutters
Interior shutters and shades are generally the least effective shading measures because they try to block sunlight that has already entered the room. However, it is the least expensive choice to the home builder because interior shading is usually provided by the home buyer. The most effective interior treatments are solid window shades with a reflective surface facing outside. In fact, simple white roller blinds keep the building cooler than more expensive louvered blinds, which do not provide a solid surface and allow trapped heat to migrate between the blinds into the building.
