TEMPERED GLASS
Thermally tempered glass is approximately four times stronger than float glass of the same thickness and configuration. Tempered glass is often referred to as "safety glass" because it meets the requirements of the various European Building Regulations and Standards that set standards for safety glass. This type of glass is intended for general glazing, safety glazing such as in sliding doors, stacker doors, bi-fold doors, building entrances, bath and shower enclosures, interior partitions and other uses requiring increased strength and safety properties. Tempered glass cannot be further processed such as cutting, drilling, edge grinding, after toughening any alterations, such as sandblasting or acid-etching will weaken the glass and can cause premature failure.
