We use 6mm toughened glass for splash backs. 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 (aka: annealed glass) creates. The granular chunks are less likely to cause injury.
Glass for your splashback can be paint on desired colour form RAL colour palette which you can browse by downloading our RAL colour chart by cliking RAL logo below.
