As energy codes become more stringent; maximizing the energy efficiency of the glazing used in buildings becomes of greater importance.
Glazing typically occupies 10 to 20% of a building’s exterior. Glazing loses more heat per square foot of an area in winter and gains more heat in summer than any other surface in a building. The U.S. Dept. of Energy estimates that energy lost through windows accounts for up to 50% of a building’s energy loss. It also estimates that the amount of energy lost through windows each year is $35 billion.
Many new solutions have been proposed to reduce heat transfer through windows and one such technology which is currently growing in prominence is vacuum insulated glazing (VIG).
