Insulated glazing (IG), more commonly known as double glazing (or double-pane, and increasingly triple glazing/pane), consists of two or three glass window panes separated by a vacuum or gas filled space to reduce heat transfer across a part of the building envelope
Toughened or tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the inner surfaces into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards of plate glass (aka: annealed glass) creates. The granular chunks are less likely to cause injury.
When designing with glass, there are a wide range of options to choose from to create a truly unique project. One option in particular—reflective glass—has some significant aesthetic and performance benefits. Even when transparent glass is in vogue, there are specific applications when tinted, reflective glass can be the superior choice. In fact, there are even reflective glasses that provide the solar control benefits of low-e coatings.
Frosted glass is produced by the sandblasting or acid etching of clear sheet glass. It has the effect of rendering the glass translucent by scattering of light during transmission, thus blurring images while still transmitting light.
