Frequently Asked Questions

Understanding Fire Classification

There are different types of fire classification which can be simply described as:

(E) – INTEGRITY: The ability of a component or construction to maintain the integrity of the element on one side only, without spreading the fire to a non-heated side as a result of penetration of flames or hot gases.

(EI) – INTEGRITY & INSULATION: The ability of a component or construction to maintain integrity of the element on one side only, without spreading the fire as a result of a significant heat flow from the heated side to the non-heated side.

Can I buy my own glass?

No, to ensure compliance and traceability all frames are supplied glazed with fire rated glass which conforms to our certification and test reports.

Can you manufacture any size of window?

Fire rated windows are restricted by size and design and can only be manufactured as fixed panes. Call our sales team on 01695 732525 to discuss your requirements.

How do I install fire windows?

Installers should be trained by a recognised scheme for fire products, for example FIRAS.

Can I have openers in my window?

No, all fire rated windows must be manufactured as fixed panes.

What’s the difference between a fire window and fire rated window.

Standard windows can in many cases be designed to provide an escape route in the event of a fire. These egress windows should provide an unobstructed openable area that is at least 0.33m2 with no dimension being less than 450mm. A clear unobstructed opening 450mm wide by 750mm high would meet this criteria.

Fire rated windows are designed to prevent the passage of fire from one location to another for a period of 30 or 60 minutes.

Will you deliver my frames?

Nationwide delivery is available.

Do you provide evidence of conformity?

All windows are manufactured in accordance with our test evidence from EXOVA Warringtonfire. Exova Warringtonfire is a world leading independent Certification, Fire testing, Mechanical testing and Fire Engineering organisation.
