What are spectrally selective coatings

Spectrally selective coatings are advanced coatings applied to glass that filter and control the amount of solar energy that enters a building.

Spectrally selective coatings are an advanced technology designed to maximize natural light while controlling heat and UV radiation. By selectively filtering out infrared (heat) and ultraviolet (UV) rays, these coatings help keep homes cooler in the summer and warmer in the winter without sacrificing brightness. Applied to windows and doors, they reduce heat transfer, lower energy bills, and protect furnishings from UV damage while maintaining a bright and natural indoor environment.

Some examples:

  • Low-E Coatings: Reflect heat while letting visible light through, reducing heat gain in warm climates.
  • Solarban 70XL: Provides high visible light transmission and significantly blocks solar heat, used in energy-efficient windows.
  • Pilkington Suncool™: Balances solar control with high visible light transmission, ideal for reducing cooling loads.
  • Guardian SunGuard: Offers various coatings optimized for solar control and maximizing natural daylight.

These coatings offer year-round benefits by reducing energy consumption in both summer and winter, protecting interiors from fading, and improving overall indoor comfort. They can also increase your home’s resale value by enhancing energy efficiency. Available in customizable tints, spectrally selective coatings can complement any home design without darkening the windows.

Environmentally friendly and compatible with multi-glazed windows, spectrally selective coatings further enhance insulation and sustainability by reducing the need for heating and cooling.
