Toughened safety glass is required in certain areas. Please see the building regulation information page if unsure whether to use toughened glass or float glass.

Laminated glass is two pieces of annealed glass which is stuck together with a film. Laminated glass is classed as a safety glass usually used for extra security such as shop fronts and part Q building regulation requirements.
