ThermaCoat Solar Reflective Colors

Designers know that color is one of the most effective ways to enhance a home’s charm and curb appeal. It’s the finishing accent that turns a nice home into a “wow” home. Available in 12 of the most popular designer colors, ThermaCoat lets you personalize your windows and doors to bring out the best in your home.

Thermal Performance

  1. Ultraviolet (UV) light block calculations performed using Lawrence Berkeley Laboratories Window 4.1 program. Percentages indicate amount of UV transmittance blocked from the interior using a ¾” glazing unit.
  2. Visible light transmittance indicates the amount of outside light reaching the interior as calculated using center of glass. Higher percentages mean more outside light reaches interior.
  3. U-factor represents the amount of heat transfer as measured in accordance with NFRC 100-2001, calculation uses total window unit, and assumes ¾” glazing with a ½” airspace. Lower is better.
  4. Solar heat gain coefficient (SHGC) measures the amount of solar radiation entering the building. As measured per NFRC 200-2001 with the Window 4.1 and Frame 4.1 modeling programs. Lower is better.
