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.
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 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.
Transmittance
Ratio of light or heat that can pass through the glazing surface.
Triple glazing
Three panes of glass enclosing two hermetically-sealed air spaces.
Thermal expansion
Change of material size as a result of temperature change.
Toughened Glass
Toughened glass is two or more times stronger than annealed glass. When broken, it shatters into many small fragments which prevent major injuries.
Transparent
Clear, permitting vision.
Translucent
Allowing light to pass through diffusely.
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.
Transom
A horizontal framing bar between glass panes.
Tinted glass
See "Body tinted glass"
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.
