What is high performance glazing?

High performance glazing refers to glazing systems that are designed to provide enhanced energy efficiency, comfort, and durability compared to standard glazing systems. These systems may incorporate a variety of advanced technologies and materials to achieve these benefits. Examples of high performance glazing include:

1. 1. Insulating glazing units (IGUs): IGUs consist of two or more layers of glass separated by a spacer with a layer of gas in between, which acts as an insulating layer and reduces heat transfer.
   2. Low-emissivity (low-E) coatings: Low-E coatings are thin metallic oxide layers applied to the surface of the glass that reduce the amount of infrared and ultraviolet light that passes through the glass, improving energy efficiency.
   3. Solar control coatings: Solar control coatings are applied to the surface of the glass and can reflect or absorb certain wavelengths of light to reduce heat gain and glare.
   4. Smart glass: Smart glass, also known as switchable or dynamic glass, can change its level of transparency based on external conditions, such as temperature or sunlight.
   5. Self-cleaning coatings: Self-cleaning coatings use UV light and rainwater to break down dirt and grime, reducing the need for manual cleaning.

High performance glazing can help to improve the energy efficiency of a building, reduce heat gain and glare, improve comfort, and reduce maintenance requirements.
