Fire Windows

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

REHAU S706 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.


RAUFERNO fire rated windows are designed to prevent the route of fire from one location to another for a period of 30 minutes. They are tested to comply with BS 476 Part 20 & 22. RAUFERNO frames offer 30 minutes integrity only.


Can you manufacture any size of window?

RAUFERNO 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.


Can I have a sash in my window?

No, all RAUFERNO windows must be manufactured as fixed panes.


Will you deliver my frames?

Nationwide delivery is available.


Can I buy frames unglazed?

No, to ensure compliance and traceability all frames are supplied glazed (20mm IGU) with fire rated glass which conforms with our certification and test reports.


You can select from clear/obscured and wired or unwired glass.


How do I install fire windows?

To ensure RAUFERNO windows are installed correctly all installers should be trained by a recognised scheme for fire products, for example FIRAS.


Do you provide evidence of conformity?

All windows are supplied with a certificate of conformity, administered to Hart & Co by EXOVA Warringtonfire. Exova Warringtonfire is a world leading independent Certification, Fire testing, Mechanical testing and Fire Engineering organisation.
