Window system
REHAU
Mainstream to upper-mainstream, with a strong engineering reputation.
Overview
About REHAU
REHAU is often mentioned in the same breath as VEKA, and for good reason: both are large German systems companies with mature UK supply chains. Homeowners frequently see the two quoted against each other.
The differences that matter to you are usually the range, the external profile shape and the glazing and hardware specification rather than the badge on the profile.
Ownership: German polymer engineering group supplying PVC-U window systems to UK fabricators.

Weighing it up
Strengths and considerations
Strengths
- Strong engineering reputation and consistent long-term availability
- Widely fabricated, so competitive comparison is straightforward
- Range choice covers both modern and more traditional appearances
Considerations
- As with any widely fabricated system, the fabricator matters as much as the profile brand
- Ranges differ significantly — a quotation should name the range, not just "REHAU"
Where it fits
Typical applications
- Replacement windows across most housing types
- Projects wanting a recognised European system
- Vertical slider replacements where appropriate

- 03What is the glass specification, including spacer bar?
The Glazora view
Comparing REHAU with VEKA on brand alone tells you very little. Compare the ranges, the glass, the hardware and the fabricator — that is where real differences appear.
