Why Windows Matter

Although they constitute only 10% of the surface area of a typical home, traditional windows are poor energy performers. Windows usually account for 30-40% of the heat loss in winter and often add to cooling peaks and discomfort in summer.

Switching from today’s code compliant, double pane window in a new home to new R5 solutions can save 7-16% of a home’s energy use, depending on climate. In an older home, retrofitting its single glazed windows with R5 windows can provide a greater energy savings.
