Which type of glass is designed for thermal insulation purposes?

Insulating glass is specifically designed to provide thermal insulation in buildings. It typically consists of two or more glass panes separated by a sealed air space, which significantly reduces heat transfer between the interior and exterior environments. This construction limits the amount of conductive and convective heat loss, helping to maintain consistent indoor temperatures and improve energy efficiency. Additionally, insulating glass can enhance soundproofing and reduce condensation issues by keeping the interior surface warmer in colder weather.

The other types of glass listed do not primarily focus on thermal insulation. Wired glass, for example, is known for its strength and safety features, making it suitable for fire-rated applications but not specifically designed for thermal performance. Sheet glass and plate glass are generally flat and used for various applications but do not offer the same insulating properties as insulating glass.
