Cortizo's top-performance system. 84mm, Uw 0.66 W/m²K, cool-temperate PassivHaus certified. Made in Spain at premium German brand performance.
The Cortizo A 84 PassivHaus HI is one of the most impressive systems we've installed. It's exceptional that a Spanish manufacturer has achieved PHI cool-temperate certification with Uw of 0.66 W/m²K.
The Hidden Sash variant is spectacular: only 66mm visible section. The result is an ultra-minimalist window where you practically only see the glass. Perfect for contemporary architecture.
The price is 15-25% lower than PassivHaus systems from German brands with equivalent performance. Shorter delivery times from Spanish manufacturing. For passive houses and nZEB buildings, very hard to beat.

Yes. The A 84 PassivHaus HI is certified by the Passive House Institute in Darmstadt for the cool-temperate category. It achieves Uw of 0.66 W/m²K. Exceptional for a Spanish manufacturer.
The guide price starts at €420 for a 1-sash casement. Significantly cheaper than German PassivHaus systems — the difference can be 15-25%.
Both are top-performance PassivHaus systems. The A 84 HI achieves Uw 0.66 vs 0.7 for the Veka 82. Cortizo also offers the Hidden Sash variant, faster delivery and 15-25% lower price. Veka 82 has a longer track record in Spain.
