What type of glass is designed to reduce heat transfer by having two or more sheets with an air space?

Insulating glass is specifically designed to minimize heat transfer and improve energy efficiency in buildings. This type of glass typically consists of two or more panes that are separated by a sealed airspace, which acts as an insulating layer. This design significantly reduces the conduction of heat between the inside and outside of a structure, making it effective in maintaining comfortable indoor temperatures while minimizing heating and cooling costs.

The airspace between the panes slows down the transfer of heat, which can be particularly beneficial in climates with extreme temperatures. Additionally, insulating glass can also reduce condensation, noise transmission, and enhance overall thermal comfort.

In contrast, wired glass is primarily used for safety and security, offering a protective layer against breakage. Patterned glass is utilized mainly for aesthetics and privacy but does not provide the thermal efficiency of insulating glass. Plate glass is a single sheet of glass, which lacks the heat-insulating qualities provided by multiple sheets with air spaces.
