Float glass panels heated and then cooled rapidly in a controlled environment. This process makes the glass several times stronger than regular glass. It also makes it safer because when broken it yields small pebble-like fragments.
Standard window glass that has been heated to very high temperatures, then quickly cooled, so that if broken, the glass breaks into small, safer pieces instead of dangerous shards. Tempered glass is also referred to as safety glass, and it's typically required by building codes to be used in glass doors and windows in areas where the glass is prone to breakage. All safety glass must be marked as such; a small identification is usually etched into the glass at one of the bottom corners.
GLASS REHEATED TO ALMOST ITS MELTING POINT, THEN QUICKLY COOLED DOWN. ALTERED BY THIS PROCESS, THE GLASS IS STENGTHENED SUCH THAT IT IS MORE THAN FOUR TIMES STRONGER THAN MOST ANNEALED GLASS. WHEN IMPACTED, IT DOES NOT SHATTER INTO LARGE, JAGGED PIECES; INSTEAD, IT BREAKS INTO SMALL PIECES. IT IS REQUIRED WHERE EVER THERE IS DANGER FROM BROKEN GLASS.
Glass created by heating it to just below its melting point, then rapidly cooling its surface and allowing the inner core to cool naturally. It is approximately 5 times stronger than regular glass. It can also "flex" significantly more without breaking and it resists impact, shock, thermal and mechanical stress. If it does breaks, tempered glass will fragment into small rounded pieces giving it a strong safety advantage. U-factor (U-value): A measure of the rate of non-solar heat loss or gain through a material or assembly. It is expressed in units of Btu/hr-sq ft-°F (W/sq m-°C). The lower the U-factor, the greater a window's resistance to heat flow and the better its insulating value.
Often called safety glass, tempered glass does not shatter as easy as non-tempered glass. When it does break, it crumbles into very small pieces to reduce the threat of injury. Used in all doors and most windows within 18 inches of the floor.
A safety glass strengthened through the process of heating, than rapidly cooling, creating a tensile strength that causes the glass to resist breakage, yet disintegrate into small pebble-sized particles, but not into slivers, if a break occurs. Tempered glass is a type of safety glass and is available in most glass types, colors and thickness.
Glass that is treated with heat during the manufacturing process. Safety glass can withstand abnormal force or pressure on its surface and doesn't break into sharp pieces. Code requires tempered glass in all doors (including patio doors) and in windows that are located near doors, bathtubs or showers. Also called safety glass.
glass that has been annealed or strengthened bt a process of grandually healing and cooling. Once a piece of glass has been tempered, it cannot be cut. If it breaks, it breakes into many small pieces. By code, all shower doors must be made of tempered glass.
As with heat-strengthened glass, it is re-heated to just below the melting point, but suddenly cooled. When shattered it breaks into small pieces. It is approximately five times stronger than standard annealed glass. It must be used as safety glazing in patio doors, entrance doors, side lites, and other hazardous locations. It can't be re-cut after tempering.
Flat or bent glass that has been heat-treated to a high surface and/or edge compression to meet the requirements of ASTM C 1048, kind FT. Fully tempered glass, if broken, will fracture into many small pieces (dice) which are more or less cubical. Fully tempered glass is approximately four times stronger than annealed glass of the same thickness when exposed to uniform static pressure loads.
Tempered and heat-strengthened glass is less brittle, but cannot be cut. These types of glass can be up to two-to-four times stronger than annealed glass. If tempered glass is broken, it disintegrates into small fragments. For this reason, tempered glass is commonly used in swinging doors, sliding patio doors and storefront windows.
Float glass that is heated and then cooled rapidly to make it several times stronger than annealed glass. Standard in all doors, tempered glass is safer than annealed glass because when it is broken it falls into pebble-like pieces without sharp edges.
Treated glass that is strengthened by reheating it to just below the melting point and then suddenly cooling it. When shattered, it breaks into small pieces. Approximately five times stronger than standard annealed glass; is required as safety glazing in patio doors, entrance doors, side lights, and other hazardous locations. It cannot be recut after tempering.
glass that has been annealed or strengthened by a process of gradually heating and cooling. Once a piece of glass has been tempered it cannot be cut. If it breaks, it breaks into many small pieces. By code, all glass shower doors and enclosures must use tempered glass.
Specially treated to maximize resistance to breakage and minimize injury potential if broken. Is available in Clear or LowE for additional cost. Required for some specific window applications. Consult local building codes for requirements.
Glass that is strengthened through the process of heating and then cooling the surfaces rapidly. This creates surface compression and tensile strength that causes glass to resist breakage, yet disintegrate into small pieces if a break occurs. Fully tempered glass must have a surface compression of 10,000 psi. This process produces glass four times more impact resistant than non tempered glass.
Glass that has been heat treated to produce a product that is four to five times stronger than annealed glass. Tempered glass, when broken, will disintegrate into many small pieces which are more or less cubical, these pieces are not as likely to cause personal injury - thus the term safety glass.
Glass heat treated to withstand greater than normal forces on its surface. It is difficult to break and withstands heat better than untreated glass; when it breaks, it shatters into small pieces to reduce shard hazards.
Glass that is treated with heat in its manufacturing, creating a product that can withstand abnormal force or pressure on its surface, and which does not break into sharp pieces; code requires tempered glass in all doors (including patio doors) and on windows that are located near doors.
