MiGlass Ltd

Toughened safety glass provides architects and specifiers the ability to fully unleash the beauty and functionality of glass whilst conforming to the latest building regulations. The toughening process dramatically increases the mechanical strength of glass by up to five times the equivalent thickness in annealed glass. In the event of breakage toughened safety glass does not shard like ordinary glass but instead fragments into small generally blunt pieces providing reduced risk of injury. All our toughened safety glass is produced in accordance with BS EN 12150-2:2004 Glass in Building. Our factory and production controls are fully compliant with all the latest regulations and MI Glass are proud to have been awarded BSI Kitemark™ accreditation for our safety glass. To further ensure the quality of our product we only source from well-established Glass Manufactures such as Pilkington and Saint Gobain whose products conform to BS EN 572. Technical Specifications Maximum Size 4600 x 2100 Thickness Range 4mm to 19mm

Despite the best efforts of manufacturers float glass can contain imperfections that can cause heat treated or tempered glass to spontaneously fracture. This is because the rapid heating and cooling associated with the tempering process can cause inclusions such as Nickle Sulphide (NiS) to contract and become trapped in this shrunken state. Over time these inclusions expand creating additional stress in the glass which can, over time, cause toughened glass to spontaneously break sometimes months or even years after installation. Mi Glass will always recommend that heat treated glass (in safety critical locations such as partitions and overhead balustrades) is heat soak tested to reduce the possibility of spontaneous breakage. All our heat soak products are tested in accordance with EN 14179-1. This involves placing toughened glass inside a testing chamber and raising the temperature to approximately 260°C. The glass in then held at this temperature for a period of time thus accelerating NiS expansion and causing any affected panels to break in the testing chamber.
