Laminated Glass
Capable of withstanding an attack.
Piles of glass are bonded - or laminated - together with a layer of polymer film (PVB) in between. By using heat and pressure, air bubbles are eliminated from the laminate (in equipment called an Autoclave) so that it appears optically as a single sheet. 

 

Toughened Glass
Used for areas in need of extra safety & security, glazed doors and glazing adjacent to doors as standard. Float glass is heated to about 650C in a furnace, then quenced with air jets so that the surfaces are cooled quickly and the inside core more slowly with the surfaces going into 'compression' and the core going into 'tension'.

Technical Information:-
However you use glass it is essential for safety and performance reasons that it is correctly specified and installed. Common areas of impact risk, where it is recommended that impact safety glass to BS 6206 is installed, include: Glazed doors, Glazing adjacent to doors, Low level glazing, Bathroom areas, Protective barriers, Furniture and cabinets.
