Bear Glass

Laminated (or compound) glass consists of two or more sheets of glass with one or more viscous plastic layers "sandwiched" between the glass panes. The solid joining of the glasses takes place in a pressurized vessel called an autoclave (similar to an oven). In the autoclave, under simultaneous heating of the already processed layers of glass and special plastic, lamination occurs. When laminated safety glass breaks, the pieces remain attached to the internal plastic layer and the glass remains transparent.
Laminated glass - Laminated glass is a combination of two or more glass sheets with one or more interlayer’s of plastic (PVB) or resin. In case of breakage, the interlayer holds the fragments together and continues to provide resistance to the passage of persons or objects.
Light-to-solar-gain ratio - The ability of glass to permit sunlight to pass without excessive solar heat gain.
Liquid crystal glazing - This is laminated glass, with a minimum of two clear or colored sheets of glass and a liquid crystal film, assembled between at least two plastic interlayer’s. In the OFF state, the liquid crystals are not aligned, which prevents vision, yet allows light to pass through the glass. When is it switched ON, the liquid crystals align, turning the glass transparent and allowing vision through the glass.
Lite of glass - A single piece of glass, regardless of thickness.
Low Emissivity Glass - Commonly known as "low-E" glass and often used in double and triple glazing units, this window glass has a special thin-film metallic or oxide coating which allows the passage of short-wave solar energy into a building but prevents long-wave energy produced by heating systems and lighting from escaping outside. Low-E glass thus allows light to enter while also providing thermal insulation.
Low-emittance (low-E) coating-Microscopically - thin coating of metal oxide, which allows the sun's heat and light to pass trough the glass into the building. At the same time it blocks heat from leaving the room, reducing heat loss considerably.
