What is a Single Glass ?
Definition of Single Glass in Construction Single pane of glass, as opposed to an insulated glass, which is two or three layers of glass, sealed together with an air space that is filled with a special gas. The intent of the multiple layers of glass is to increase the insulation performance of the glass. The use of single glass panels is becoming less common, due to the need for increased insulation values as well as special requirements such as security, light transmission, etc. Single glass, if tempered, can be extremely strong and durable. This type of single glass can be used in vision panels and specialty applications that require visual clarity, but no real insulating or special light transmission qualities.
