Buyer's guide
Rehau, Kömmerling, or Veka: An honest review without marketing hype
Comparison of the German 'big three“ in Spain (2026)
This is not a choice between “bad” and “good.” It is a choice between Audi, BMW, and Mercedes. All three brands are market leaders, all have safe compositions, and all are white and warm. The difference lies in the engineers' philosophy: gloss or matte, frame rigidity or sleek lines.
Rehau — Aesthetics and Gloss
Rehau's philosophy is more glass, less plastic. They are renowned for their unique HDF (High Definition Finishing) surface. It is perfectly smooth and glossy.
- • Surface: Glossy. Micro-pores are closed, so Spanish dust is easily washed off.
- • Shape: Beveled, shaped glazing beads are often used for visual lightness.
- • Feel: An “elegant,” bright window that sparkles in the sun.
Kömmerling — Standard
The most popular German brand in Spain. They have their own factory in Spain, which makes them “one of their own” for the local market. The golden mean in all respects.
- • Surface: Satin (semi-matt). Pleasant to the touch, somewhere between Rehau and Veka.
- • Technology: A wide range of 76 mm systems, perfectly tailored to Passivhaus standards.
- • Feeling: Calm, modern European style.
Veka — Engineering
Veka's philosophy is monumentality. It is the only brand that prioritizes rigidity over design. They use closed reinforcement (reinforcement profile - square inside).
- • Surface: Elegant deep matte. No glare, looks sleek and expensive.
- • Stability: The most rigid frame. Critically important for windy areas and large sashes.
- • Feel: Reliability, solidity, monolithicity.
Dry facts: differences in the details
| Parameter | Rehau | Kömmerling | Veka |
|---|---|---|---|
| Texture (to the touch) | Smooth gloss | Silky satin | Velvety matte |
| Sun reflection | Glare (shine) | Soft glow | No glare |
| Shade of white | Warm (Milky) | Cool (Bluish) | Neutral white |
| Reinforcement (Metal) | P-shaped / G-shaped | Complex cross-section | Closed square |
| Main advantage | Easy maintenance | Balanced characteristics | Stable shape |
So what should you choose for your home?
There is no universal answer. The choice depends on where your property is located and what is important to you personally. Which brand do you prefer? We love them all and know how to work with them.
- — Are design and light important? Rehau Delight provides more light, and its glossy surface always looks like new.
- — High floor or strong winds? Veka with closed metal will be the safest solution.
- — Energy-efficient project? The Kömmerling 76/88 line is a good choice for warm homes in Spain.
Don't guess. We will calculate the costs in different profile systems, explain the difference in price, and help you make an informed decision.
