Heat Strengthened Glass

Additional Details

Safex Heat Strengthened Glass is a semi tempered glass which retains the normal properties of raw glass with the exceptional strength and breakage characteristics. The glass is processed in horizontal furnace in which approximately 650°C is maintained to heat up the raw glass, and cooling cycles being less. This process is generally similar to heat temperatures being lower and cooling cycles being less rapid.

Properties

    Heat Strengthened Glass is approximately two to three times stronger than annealed glass of equal thickness.
    It breaks into large pieces and remains in window frames.
    It provides resistance to thermal stress associate with high performance glazing material such as Low-E glass, Reflective glass and Tinted glass.
    It provides less optical distortion.

Specification

    Maximum Size: 2440mm x 3660mm
    Minimum Size:300mmx300mm
    Thickness: 3.5mmto 19mm
    Glass Type: Clear, Tinted, Reflective, Low-E

Precautions

    Once heat strengthened the glass cannot be cut, drilled, beveled, deep etched or any kind of acid treated.
    As glass is heat treated, bow, wrap or process roller mark distortions may be evident. This is within limits set by ASTM standard.
