Brand Comparison
Rehau vs Kömmerling vs Veka
Picking between Rehau, Kömmerling and Veka is a bit like choosing between Mercedes, BMW and Audi
All three are heavyweights of German engineering, and whichever you go for you end up with a premium window. The difference is in the small print: the exact shade of white, the bead geometry, the PVC recipe and, above all, what your glazing actually has to do. Let's put them side by side and look closely.
| Parameter | Rehau The Innovator | Kömmerling The Green One | Veka The Workhorse |
|---|---|---|---|
| Signature Tech | RAU-FIPRO (fibreglass) | Greenline (lead-free) | Closed-box reinforcement |
| Surface | HDF — glossy, wipes clean | Silky matt, bright white | Semi-matt, understated |
| Wall Thickness | Class A and B | Mainly Class A | Always Class A (3mm) |
| Sealing | Twin-lip gaskets | Co-extruded (bonded) | Removable rubber seals |
| Styling | Chamfered or square profiles | Pure classic lines | Soft, rounded edges |
| Best For | Early adopters | Families wanting a greener home | Large panoramic openings |
Rehau — The Innovator
RAU-FIPRO (the same kind of material used in Formula 1 chassis) carries oversized sashes without any steel inside. The HDF surface is so smooth a single wipe leaves it spotless.
Go for Rehau if you want cutting-edge tech or unusual window shapes.
Kömmerling — The Green One
The lead-free Greenline recipe is a real plus for children's bedrooms and anyone prone to allergies. Its cool "blue-white" tone holds up without yellowing for 40 years.
Go for Kömmerling when eco-credentials and a crisp finish are your priorities.
Veka — The Workhorse
A closed, square steel core means the window stays true even twenty floors up in a gale. Walls are a strict 3mm (RAL standard). Think of it as the tank of the window world.
Go for Veka on high floors, exposed elevations or with heavy glazing units.
So Why Is the Choice So Tricky?
Every profile looks perfect on paper, and honestly they all are. But the window that's spot on for a detached house can be the wrong call for a flat on the fifteenth floor.
- — Veka copes better with wind loads, but it weighs more
- — Rehau Delight pulls in around 10% more daylight, with some reinforcement trade-offs
- — Kömmerling wins on whiteness, though the price can sit higher
There's no need to second-guess the technical details from a photo. We know these profiles inside out.

The engineering that turns Rehau windows into the benchmark for quality
RAU-FIPRO: Steel-Free
The fibreglass reinforcement at the heart of GENEO profiles. Roughly 40% warmer and 40% lighter than a steel-reinforced equivalent, and stronger with it.
HDF Finish
High Definition Finishing leaves a flawlessly smooth surface that resists scratches, grime and UV for decades on end.
More Daylight
Because RAU-FIPRO does the heavy lifting, Rehau profiles can stay slim while spanning very large openings, so more of the wall becomes glass and more light gets in.
FAQ
Rehau Windows: Your Questions Answered
What does a Rehau window cost, fully installed?
Let's split it honestly. The window on its own (supply only, white profile, standard 4/16/4 glass, before VAT) starts around €170 for a 1x1 m EURO 70 casement and €195 for the tilt-and-turn version; the same size in premium SYNEGO is closer to €292-297. Fitting in Spain runs about €80-150 per opening, with another €20-40 to strip out and dispose of the old frame. In practice a typical 1x1 m standard-PVC tilt-and-turn lands near €335 installed, and most fitted PVC windows fall in the €280-480 per m² band.
Which Rehau model suits a flat best?
For most Spanish flats the safe bet is Rehau SYNEGO (around €292 supply for a 1x1 m casement). Its deeper, multi-chamber section knocks back street noise and keeps the air-con working less hard. EURO 70 (a 1x1 m casement from roughly €170 supply) is the sensible pick for terraces or a tighter budget. GENEO is the one to reach for on villas and passive houses.
What makes GENEO special, and why does it cost more?
GENEO is the steel-free profile, reinforced inside with RAU-FIPRO fibreglass (the F1 material again). The window comes out about 40% lighter, won't sag over time, and runs warmer than any steel-cored rival. It sits above SYNEGO on price, so treat it as an investment: you pay more up front and claw it back on heating and cooling for years.
Will the profile yellow in the Spanish sun?
No. The genuine German profile uses the HDF (High Definition Finishing) surface: a glossy skin that sheds dust and holds its colour under UV. Rehau's official whiteness warranty runs to 10 years, while real-world service life comfortably tops 40.
Where are Rehau windows made?
Rehau is a German firm. The profile is extruded in its German and Polish plants to one DIN standard, then the finished window is built to your exact sizes at a certified fabricator that Rehau engineers audit every year.
Can I have a colour other than white?
Absolutely. Anthracite (Satin Black) and natural wood-grain finishes are the popular choices right now. Laminated colour adds roughly 20-30% to the window price and a couple of extra weeks of lead time, but the result looks like fitted furniture and lasts just as long. And remember the 40% IRPF deduction for energy-efficient windows, which runs to the end of 2026.
