Home Products Fire Rated Glazing

Fire protection regulations are comprehensive, complex and diverse. The fire protection standards of building structures called for by each particular supervisory body vary according to type and use of the building, architecture, as well as the specific installation situation.

These diverse regulations and requirements for the use of fire-resistant glazing have led to the definition of the European standardised fire-resistance performance classification which comprises three classes:

INSULATION Class EI: Fire-resistant glass in this category offers highest level of protection from fire, smoke and radiant heat for a defined period of time (from 30 up to 180 minutes).

INTEGRITY Class E: Fire-resistant glass which remains transparent in the event of fire offers protection from fire and smoke but does not reduce the transfer of dangerous radiant  heat in the event of a fire (integrity only performance).

INSULATION & INTEGRITY Class EW: Glass in this category offers an integrity performance (protection from fire and smoke) whilst reducing transfer of dangerous radiant heat.

Contact our office team today for more information.


We can advise you on the fire glass specification you need to ensure your project complies. We just need to know:

Is it for internal or external use?

Is it required for a door or a screen?

Is it being glazed into timber or steel?

Does it need to be clear or wired?

What fire rating needs to be achieved?
