Heat absorbing glass

Jump to navigation Jump to search


A type of solar control glazing that has been coated with a film that absorbs, or reflects infrared radiation. First produced in 1951, heat absorbing glass is used on building and automobiles to minimize interior heating and reduce glare. In 1952, the Lever House in New York City was built with Solex heat absorbing glass (Konrad et al. 1995). Heat absorbing glass is tinted (gray, green, bronze, etc.) to absorb the IR energy. Typical IR Shading Coefficients for heat absorbing glass are 0.65 - 0.73.
