Rio Door

The latest addition to REHAU’s Rio flush fit range is a single open-out door that complements the established Rio window system aiming to help fabricators and installers provide a consistent aesthetic to homeowners wanting matching windows and doors. Based on homeowner insight and the popularity of Anthracite Grey Grained, Simply White and Pearl Grey colours for the Rio Flush Fit window, REHAU’s new flush fit door is customisable in a number of colours.

  • Extension to the existing Rio flush fit range with introduction of the Rio door.
  • Single open out residential door complements the established Rio window system.
  • Option to specify either TOTAL70C or TOTAL70S outer frames.
  • Dedicated butt hinges designed for the flush door system.

Rio French Door

The new Rio flush fit French door uses REHAU’s Deep Bottom Rail, which was developed to complement the original window system. Consequently, installers and fabricators do not need a new-door sash, further streamlining fitting. Alongside this, the new door has been certified to the PAS 24 security standard, having been tested at its maximum size – 1900mm x 2250mm.

Latest Innovation

Square Edge Bead - 1081550

REHAU are pleased to announce that we have introduced a 28mm Square Edged Bead as part of the Rio flush fit window range. The new Square Edge Bead allows for a more contemporary style flush fit window to be manufactured for greater versatility and styling. Available as a special-order option, the new Square Edge Bead can be used internally to complement a modern interior design with a grey foil, but keep a traditional timber look externally with a Turner Oak foil. 

The Square Edge Bead will also fit with the Heritage vertical sliding window system. It provides a pvcu square bead option and works with the original aluminium bead where catches are fitted and if required for security standards. The Square Edge Bead design incorporates the low level detail that is already an integral part of the Rehau bead range. Currently available from stock, just ask your local sales contact for more information.
