U-Values from 1.2 W/m²K — A+ BFRC Rated
TOTAL70 5-chamber profiles achieve whole-window U-values from 1.2 W/m²K with double-glazed Low-E units, dropping to 0.9 W/m²K with triple glazing. BFRC rating reaches A+ — the highest commonly specified rating. Comfortably exceeds Approved Document L (1.4 W/m²K maximum).
5- and 6-Chamber Multi-Cavity Profile
Internal air chambers are the primary thermal-insulator in any uPVC profile. Rehau's TOTAL70 has 5 chambers, TOTAL70 Edge has 6, AGILA sash has 6 — significantly more than the 3-chamber budget systems sold by most installers. The result: better thermal performance, stiffer frames, less heat loss at the seal.
AGILA Sliding Sash — Authentic Victorian Look
Rehau AGILA is the most convincing uPVC reproduction of an original Victorian or Edwardian timber sash window. Astragal bars, Georgian-bar overlays, run-through horns and authentic deep bottom rail. Approved by many planning officers as a like-for-like replacement in conservation areas where timber sash is the planning expectation.
Rio Inline Flush Casement — Heritage Detail
Rehau Rio is a flush-casement uPVC system where the sash sits perfectly level with the frame — closely mimicking traditional timber casement. Increasingly approved by conservation officers as a like-for-like replacement for original timber where uPVC is acceptable.
PAS 24 Certified, Multi-Point Locking
All Rehau opening profiles are PAS 24:2022 certified with multi-point shootbolt locking, internally beaded glazing (so glass can't be removed from outside), and laminated inner glass options on opening sashes. Compatible with Secured by Design configurations.

Frequently Asked Questions
What is Rehau?
Rehau is a privately-owned German polymer-engineering company founded in 1948 and headquartered in Rehau, Bavaria. They manufacture uPVC window and door profiles, automotive components and infrastructure piping in over 170 locations worldwide. Rehau's window profiles are sold to UK fabricators who manufacture the finished window — Rehau does not sell direct to homeowners. Vitrum Solutions installs Rehau through approved UK fabrication partners.
Which Rehau systems do you install?
We install the full Rehau residential range: TOTAL70 and TOTAL70 Edge casement windows, AGILA sliding sash windows, Rio inline flush casement windows, plus matching French, single and sliding doors. We can also specify and install bay & bow window configurations and triple-glazed builds.
How energy efficient are Rehau windows?
Rehau TOTAL70 5-chamber profiles achieve whole-window U-values from 1.2 W/m²K with double-glazed Low-E units, dropping to 0.9 W/m²K with triple-glazed units. BFRC energy rating reaches A+ — comfortably exceeding the current Approved Document L 1.4 W/m²K maximum. The 6-chamber AGILA sash and Rio Inline systems perform even better thanks to additional air cavities.
Is Rehau better than other uPVC brands?
Rehau is widely regarded as the premium uPVC brand alongside Veka and Schuco LivIng. Compared to budget UK uPVC systems (Synseal, Eurocell entry-level), Rehau has more thermal chambers (5-6 vs 3), thicker outer wall thickness, more rigid frame extrusion, and significantly better long-term colour stability on darker shades. Most budget uPVC fades noticeably on south-facing installations within 7-10 years; Rehau is warranted not to.
How much do Rehau windows cost?
Typical UK installed prices: Rehau TOTAL70 casement windows £350 – £550 per opening (approximately 50% cheaper than equivalent aluminium), AGILA sliding sash windows £900 – £1,400 per opening, Rio Inline flush casement £450 – £700 per opening. All fully installed by our team, FENSA registered, with a 10-year CPA insurance-backed guarantee. Full review and pricing: /blog/rehau-windows-review-uk.
Can Rehau windows be used in conservation areas?
Often yes — but it depends on the local planning authority and whether your property is listed. Rehau Rio Inline and AGILA sliding sash both have heritage detailing (run-through horns, deep bottom rail, authentic astragal bars) that many planning officers approve as like-for-like for timber. Listed buildings normally require timber. We handle the planning consultation and supporting paperwork as part of our quote. Full guide: /blog/conservation-area-windows-uk.

Yes. Vitrum Solutions installs Rehau across Buckinghamshire, Berkshire, Oxfordshire, Surrey, Hampshire, Hertfordshire and West London. Including Beaconsfield, Gerrards Cross, Amersham, Marlow, Windsor, Ascot, Virginia Water, Weybridge, Cobham, Esher and all surrounding premium towns.
