Toughened or tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the inner surfaces into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) creates. The granular chunks are less likely to cause injury. As a result of its safety and strength, toughened glass is used in a variety of demanding applications, including passenger vehicle windows, shower doors, architectural glass doors and tables, refrigerator trays, mobile screen protectors, as a component of bulletproof glass, for diving masks, and various types of plates and cookware.

Key Features

Luxury

Shri Hari offers uPVC windows in 3 series – Premium, Luxury and Super Luxury. You can choose high-quality uPVC windows from these series, depending on the aesthetic value, design, insulation requirement, wind load, and size of the aperture, and order your custom-made uPVC windows.

Impact Resistance

A surface compression of over 10,000 PSI(69MPa) imparts about five times the impact and mechanical strength of annealed glass of the same thickness.

Thermal Cracking Resistance

Tempered Safety Glass will resist temperatures of up to approximately 295 C an temperature difference of up to approximately 250 C. In a range frm -20 C to 300 C.
