Low-E Coating Types

There are two main types of Low-E coatings that may be applied to glass. Each type of Low-E coating is used in different regions based on regional climate demands.

High-solar-gain Low-E coatings are designed for cold northern climates and allow large amounts of solar heat and natural light into a room. This Low-E coating takes advantage of the passive heat gain from the sun while keeping interior heat from escaping.

Low-solar-gain Low-E coatings are designed for hot southern climates to allow a minimal amount of solar heat to enter a room while permitting moderate amounts of natural light.
