Authentic Timber or Aluminium Look | Without the Hassle
Authentic Timber or Aluminium Look – Without the Hassle
With welded or mechanically jointed options, Fenster’s REHAU Flush Fit frames can replicate either timber joinery or aluminium sightlines.
That means installers can confidently offer a heritage or modern aesthetic using one trusted system – no extra suppliers, no compromises..
Precision Manufacturing That Keeps You on Schedule
At Fenster Trade Frames, every REHAU Flush Fit window is fabricated in-house at our Bury, Greater Manchester factory, giving complete control over accuracy, finish, and quality. Using REHAU-approved tooling and tightly monitored production processes, we achieve a consistent, factory-grade fit across every welded and mechanical joint. Because we oversee every stage from profile cutting to final inspection, installers can count on perfect alignment, faster fitting, and fewer callbacks. The result? Flush Fit frames that install cleanly the first time, helping trade professionals stay on schedule and deliver a superior finish that their customers will notice.
Built for Energy Efficiency & Compliance
With multi-chambered REHAU profiles, Rio Flush Fit windows meet Part L Building Regulations and deliver low U-values, reducing heat loss and helping homeowners tackle rising energy costs.
For installers, that means easier specification, smoother sign-off, and fewer callbacks.
Trusted Hardware = Less Callbacks
We only partner with premium suppliers, such as Winkhaus and Carl F. Group, to ensure that every Flush Fit window performs reliably.
Secure multi-point locking, precision hinges, and robust gaskets mean installers can fit once and trust the job will stand the test of time.
Designs That Win Jobs | Without the Maintenance Hassle
Homeowners want the premium look of timber or aluminium, but not the upkeep or price tag. Fenster’s REHAU Flush Fit windows deliver both, offering deep bottom rails, perfectly balanced sightlines, and authentic detailing that meet the expectations of today’s design-conscious customers.
With a wide range of REHAU foils and finishes, we handle colour-matching, quality checks, and fabrication in-house, so installers don’t waste time chasing suppliers or fixing mismatched frames. It’s a low-stress, high-margin solution that helps you sell confidently and complete every project to showroom standards.
