How Window Coverings Effect Efficiency

Also consider window coverings when choosing a shape and style of window. Two of the most efficient coverings are shades and awnings, but they only work with the right windows. Awnings need to be carefully designed alongside windows to block summer heat but maximize winter sun. Blinds and shades should be mounted close to the glass and fit snugly in the window frame to block light and insulate against extreme outside temperatures. Similarly, curtains should cover the whole window and be close to the glass.
