Low-E Coatings

Can you explain what Low-E coatings are?

Low-E glass refers to glass with a low-emissivity coating. It reduces heat gain or loss by reflecting long-wave infrared energy (heat) and therefore, decreases the U-value and solar heat gain, and in doing so, improves the energy efficiency of the glazing. Because of its relative neutrality in appearance and energy efficiency, low-E glass is widely used in residential and commercial buildings and is expected to continue to increase in usage in the coming years.

Vacuum-coated glass is available on the market in a wide range of colors and includes a number of varieties whose properties may even exceed energy-saving requirements. Guardian Industries manufactures ClimaGuard coatings at multiple locations.
