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:
- 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.
- 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.
- 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.
- 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.
- 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.
