Bear Glass

Tempered glass - Tempered (toughened) glass is two or more times stronger than annealed glass. When broken, it shatters into many small fragments, thus preventing major injuries.
Tempering - Special process of solidification of a glass sheet in order to make it particularly resistant to breakages. The result is a sheet of glass which is two or three times stronger than un-tempered glass and which, upon breakage, shatters into tiny pieces with blunt edges (the most common applications are for automotive glass.)
Thermal break - A type of metal frame that incorporates an insolating material of low thermal conductivity located between the inner and outer parts of the frame in order to reduce the rate of heat loss.
Thermal expansion - Change of material size as a result of temperature change.
Thermal mass - A special mass in a structure which is used to absorb solar heat during the day and then release the heat in the evening.
Thermal shock - When glass is exposed to high temperatures, it absorbs heat and expands. At the same time, its edges remain cooler, causing thermal stress.
Thermally insulting glazing - Double-glazed units provide thermal insulation.
Tight size - The actual size of an opening into which glass is to be glazed and is measured from the rebate platform.
Tinted interlayer - A colored plastic or resin sheet between two or more panes of glass.
Toughened Glass -(tempered glass) Toughened glass is two or more times stronger than annealed glass. When broken, it shatters into many small fragments which prevent major injuries.
Translucent - Allowing light to pass through diffusely.
Transmittance - Ratio of light or heat that can pass through the glazing surface.
Transom - A horizontal framing bar between glass panes.
Transparent - Clear, permitting vision.
Triple glazing - Three panes of glass enclosing two hermetically-sealed air spaces.
