Reflective-Coated Glass

Definition

Reflective-coated glass is glass onto which a thin layer of metal or metal oxide has been deposited to reflect light and/or heat.

Purpose

The purpose of reflective-coated glass is to reduce solar heat gain, glare, and energy consumption by reflecting a portion of incoming light and heat, improving comfort and energy efficiency in buildings.

Examples of Use

• Commercial buildings use reflective-coated glass in windows to reduce cooling costs and glare.
• Residential homes incorporate reflective-coated glass in skylights and large windows to enhance energy efficiency.
• Greenhouses use reflective-coated glass to control heat and light levels, optimizing growing conditions.

Related Terms

• Low-E Glass: Glass with a low-emissivity coating that reflects infrared light, improving thermal performance.
• Tinted Glass: Glass that has been colored to reduce light transmission and glare.
• Insulated Glass Unit (IGU): A multi-pane glass assembly with a sealed air space between panes, enhancing thermal insulation.

Notes

Reflective-coated glass can significantly improve a building’s energy performance, making it a popular choice in both commercial and residential construction.
