Spanish manufacturer with over 50 years of experience. 70mm depth, 5 chambers and prices 10-20% lower than German brands. Slim-line aesthetics inherited from aluminium.
Cortizo is a Spanish manufacturer based in Padrón (A Coruña) with over 50 years of history. This gives us a practical advantage: delivery times of 2-3 weeks vs 4-6 for German brands, and much faster after-sales service.
The A 70 has aesthetics we particularly value: slimmer, more stylish lines than other PVC profiles, a direct inheritance from Cortizo's experience in aluminium. Our clients frequently remark that it doesn't look like a conventional PVC window.
In terms of value for money, it's hard to beat. With technical performance perfectly comparable to a Veka Softline 70 or Kömmerling 76 AD, the Cortizo A 70 is 10-20% more affordable.

Yes. The Cortizo A 70 is a very solid system with outstanding value for money. Made in Spain, it combines Class A profile quality with prices 10-20% lower than German brands.
The guide price starts at €260 for a standard 1-sash casement. A 2-sash window of 120cm costs between €340 and €480.
The main difference is depth (70mm vs 78mm), chambers (5 vs 6) and thermal performance. The A 78 achieves Uw of 0.80 W/m²K vs 0.9 for the A 70, and accepts glazing up to 48mm.
Yes. With double low-E glazing, the Cortizo A 70 achieves Uw values of 0.9 W/m²K, comfortably meeting CTE 2019 in all Spanish climate zones.
Key advantages: Spanish manufacturing (2-3 week delivery), faster after-sales, spare parts in days, 10-20% lower price, and slim-line aesthetics inherited from aluminium.
