HEAT MIRROR INSULATING GLASS
According to Chris Mathis, a founding member of
the National Fenestration Rating Council (NFRC), 64
percent of the 110 million existing homes in the
U.S. have single-pane windows, which contributes
25 to 35 percent of the total energy wasted in buildings in the U.S. annually. In response, Southwall
Technologies, Inc. recently announced the ability of
Heat Mirror insulating glass to insulate against heat
loss at a record-breaking R-20/U 0.05 insulation
value—that’s equal to the insulation of a solid wall.
Heat Mirror is a technologically advanced low-emis-sivity and solar-reflective film that can be mounted
inside an insulating glass unit in a variety of configurations (one, two or three coated films, uncoated or
low-e coated glass) to provide energy conservation
performance ranging from R- 6 to R- 20. The new R- 20
Heat Mirror insulating glass consists of three heat-reflective coated films mounted inside an insulating
glass unit between two pieces of low-e coated glass.
