Tinted glass(also called heat-absorbing glass) is a type of window glass that filters out selective solar energy, reduces temperature gain through the glass and prevents an excessive buildup of heat. According to "Architectural Graphic Standards," tinted glass was developed to control and reduce glare and solar heat.
Tinted glass (or tint glass) is produced when coloring agents are added to the glass batch. These coloring agents include gray, blue, green and bronze. The addition of these colorants does not affect the primary structure of the grass, but enhances its heat-absorbing properties. Commonly used colorants include iron, chromium, copper, nickel, manganese, vanadium, cerium, sulphide and sulphur. Glass coated with a tinted film that blocks and/or reflects light and reduces glare is also considered tinted glass. The thickness of tinted glass ranges from 1/8 inch to ½ inch. Thicker glasses decrease the transmission of visible light.
Tinted glass is either single tinted or double glazed tinted glass. Single tinted glass provides a nominal level of solar control. Double tinted glass is typically available in light blue or light green. It reduces the heat gained through the sun without affecting visibility. Body tinted glass is a type of glass in which oxides of metals are added to the glass melt.
Tinted glass is used in automobile windows, commercial and residential buildings, lobbies of community buildings, showroom windows and artists' studios.
Tinted glass reduces the heat gain through windows without affecting visibility. According to "Clinical Guide to Sunscreens and Photoprotection," tinted glass reduces UV rays as compared to clear glass. Tinted glass reduces draft from cold glass surfaces and improves the shatter-resistant properties of the surface of the glass. Tinted glass enhances privacy and security and is particularly useful on seashores to reduce glare.
Black tinted glass absorbs heat and reflects it inside a room, increasing its temperature. According to "Building Systems for Interior Designers," tinted glass is vulnerable to thermal stress and requires additional heat treatment to reduce the risk of cracking. Tinted glass tends to overheat due to its solar absorption capability and is hot to the touch.
