About Toughened Glass Tab

Toughened and/or tempered glass are types of safety glass with increased strength both physically and thermally. Processed in our state of the art toughening plant and heated up to 680 degrees depending on the thickness the toughening will create ‘balanced internal stresses’ which would mean that if broken the glass would crumble into small, less harmful pieces as opposed to dangerous large shards. Such properties mean that toughened glass is suitable for use in Shower Doors, Conservatories, Table Tops, Balustrades etc...

The toughening process begins with a piece of float or annealed glass placed on a roller table at the beginning of the toughening plant, this is where the BSI Kite Mark Stamp is put onto the glass. The rollers will take the glass first through the furnace which heats the glass to above its annealing point and then moved onto the quench where it is rapidly cooled. Once both processes are complete the glass will be toughened... But bear in mind that any cutting, drilling or processing must be completed prior to the toughening process otherwise the glass will shatter.

The finished product will be 5 times stronger than float glass of the same thickness and will therefore have a greater resistance to thermal shock and stresses
