Tuff Glass is basically a semi-tempered glass manufactured on the world's No. 1 Tempering Line Tarn Glass Finland. Tuff Glass retains the normal properties of ordinary float glass including chemical resistance, hardness, expansion and deflection with the exception of strength and breakage characteristics. Tuff glass is a semi-tempered glass which has been Tuff thermally by inducing a surface compression of 6000 to 9000 psi as compared to a range of 11000 to 20000 psi in case of fully tempered glass. AL-FATTAH TUFF GLASS comes with many outstanding features that make it the instant choice over ordinary glass.

Strength as Compared to Ordinary Glass:

AI-Fattah Tuff is similar to that of stronglass but with lower level roof surface compression, it has twice the strength of ordinary glass of an equivalent thickness.

Strength in Terms of PSI:
Tuff Glass induced with compressive stress of 6,000 to 9,000 psi on surfaces and not less than 5,500 psi on edges.

High Thermal Shock Strength:
3 times more resistance to thermal stress in comparison to ordinary glass. It can withstand temperature difference of 100 °C (in a range of 50 °C to 150 °C) compared to ordinary glass which can withstand up to 40 °C. Tuff Glass provides necessary resistance to thermal stress associated with high performance glazing materials such as Tinted glass, Reflected glass and Low E glass.

Breakage Patterns:
It breaks into large pieces and does not crumble into small fragments like Stronglass. It allows the glass on its neighboring pieces support each other in the frame.

The glass can not be cut or drilled after the process of making the glass Tuff.




As can be expected with any heat-treated glass, bow, warp and or process roll distortion may be evident. This is an inherent characteristic of the manufacturing process and is within the limits set by ASTM Standard C 1048 or DIN 1249.

Applications of AL-FATTAH Tuff Glass:
Tuff Glass is best suited for spandrel and vision panels of curtain walls and structural glazing as it safeguards against thermal breakages, provides better optics than fully tempered glass, provided the calculations on wind loading are within safe limits.
It is ideal for making laminated glass panels for safety combined with strength.
It is also used in complex glass combinations like double glazed with one lite of laminated glass, pool sides, pool bottoms, aquariums etc.
