Fire Rated Windows


No longer restricted by traditional fire rated materials and construction techniques, RAUFERNO gives you the freedom to use PVC-U fire resistant windows and still comply fully with current building regulations for most protected areas, due to full certification to BS476 Parts 20 and 22.

The RAUFERNO PVC-U fire resistant windows, a patented industry first, is based upon and has all of the design and security benefits of the REHAU TOTAL70 70mm profile. 

RAUFERNO provides you with all the safety and security of traditional fire rated products, but with PVC-U’s added inherent benefits of:

  • Improved thermal insulation
  • Sound Proofing
  • Low maintenance
  • Excellent security options

With performance of all fire rated products so critical, REHAU has taken every step possible to ensure unsurpassed standards of manufacture through approved fabricators. To receive REHAU accreditation, all fabricators (who must be BSI, BBA or FIRAS accredited) must undergo certified REHAU training and provide proof of a top level QC system. To ensure correct installation, installers must be trained by a recognised scheme for fire products.


The system provides an array of design options for you to install throughout a building in the following areas:

  • Fire escape routes
  • Entrance halls
  • Deck access flats
  • Fixed windows
  • Fixed fanlights
  • Sidelights coupled to doors
