Rehau Rio

Reinventing the heritage

Building on its foundations, REHAU’s Rio windows bring an innovative, high-performance product to the forefront of their collections. With a flush fit, the Rio is reinventing the way homeowners use REHAU windows, combining timeless designs with modern functionality.

Innovation – Deep Bottom Rail

We give our customers the option of a flush sash design throughout or a deep bottom rail for alternative styles. 


The latter is one of the newest innovative features in the Rio flush fit collection, emulating the period aesthetics of timber sash windows. As an extension to the Rio range, this new profile enhances the traditional look of the Rio flush fit, exuding a heritage look and feel.


The benefits far outweigh those of original timber windows, thanks to Rio’s convenient operation and the enhanced efficiency of modern uPVC. The authentic appearance of the rail is achieved when it’s mechanically jointed at the base of the sash, using a screw ported component made from quality aluminium.

Unrivalled Weather & Security Performance

The Rio flush fit window achieves an outstanding weather performance, meeting the highest BSI ratings for resistance to weather conditions such as water, wind and air. It boasts PAS 24 Security, offering homes greater security.

Wood Finish

If you’re looking for the realistic appearance of traditional timber without the upkeep, Rio Turner Oak flush fit windows are the ideal choice. When mixed with a fully welded joint, the Turner Oak provides a quality finish which enhances the exteriors.

Aluminium look

The modern appearance of Rio flush fit windows is achieved with grey finish laminates, creating a cost-effective alternative for those who love the look of premium aluminium. This Anthracite Grey shade helps to create seamless interiors in your home.
