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).
The flat glass business of the NSG Group, operating under the Pilkington brand, is one of the world’s largest manufacturers of glass and glazing products for the building and automotive markets, with manufacturing operations in 29 countries on four continents and sales in 130 countries.
