Fire Rated Glass - FAQs
What is fire rated glass?
Fire rated glass is a specialist type of glass which acts as a barrier to stop flames and smoke from spreading should a fire break out in a building. In addition to this, the insulating qualities of particular types of fire rated glass can also provide some protection against the actual heat of a fire.
Why can’t I use normal safety/toughened/laminated glass instead?
Made from toughened or laminated glass, safety glass is specially treated to withstand impact from an object or person, making it more difficult to break and providing protection against injury. In their standard form, toughened, laminate and safety glass do not provide any fire resistance.

Does your fire rated glass come with evidence of performance based test information and a rating?
Fire rated glass undergoes rigorous testing to ensure reliable protection; we can supply a data sheet with evidence of performance based test information and a rating, should you require it.
How long will the glass provide fire protection for?
Following meticulous testing, the glass is given an official fire protection rating. The length of time the glass can provide protection against a fire typically ranges from 30 minutes upwards; this time-frame is referred to as the ‘Integrity Period’ which describes the length of time the glass has stayed in the frame and has blocked out the flames and smoke - these are factors which allow the glass to successfully pass the testing stage.
In addition to acting as a barrier against flames and smoke, some fire rated glass can also provide protection against the heat emitted from fire. This is known as the ‘Insulation Period’ which describes the length of time the glass can withstand the temperature on the non-fire side of the glass and remain intact; this also ranges from 30 minutes upwards.
