UW- value ≤ 0.66
Cortizo A 84 Passivhaus is the technological pinnacle in the PVC profile range, created for those who accept no compromises in thermal insulation. This system is officially certified by the prestigious Passivhaus Institute (Germany) for the "cool temperate climate" category, making it the ideal choice for passive houses and projects with the highest energy-saving requirements. In Spanish conditions, this window works as a powerful thermal barrier: in winter it retains 100% of heat inside, and in hot summer it blocks the heat, allowing significant savings on air conditioning.
The profile construction is impressive: 84 mm installation depth, 6 isolated air chambers and, most importantly, three sealing circuits (including the central gasket). This architecture reduces heat loss to a physical minimum. The system is designed for installing heavy triple glazing units up to 56 mm thick. By installing Cortizo A 84, you're investing in the future: these are windows that are decades ahead of modern building standards, providing luxury-class silence and climate control.

FAQs
Frequently Asked Questions about Cortizo A 84 Passivhaus
What does Passivhaus certification give to an ordinary buyer?
Even if you are not building a certified "Passive House", this status guarantees the highest quality of execution. You get a product that has passed the world's most rigorous heat loss tests. This means minimal electricity bills (air conditioning/heating) and complete absence of drafts or "cold from the window".
Why is a third sealing circuit needed?
Standard windows have two circuits. The third (middle) gasket in Cortizo A 84 divides the chamber between the frame and sash into two zones: "wet" and "dry". The hardware mechanisms are in the dry zone, which extends their service life, and the joint thermal insulation improves significantly.
How bulky does the 84 mm profile look?
The system looks solid and reliable, but not bulky thanks to Cortizo's refined proportions. However, it should be noted that the profile height (light opening) is slightly larger than standard systems, which is compensated by the ability to manufacture larger sashes.
Will installing such expensive windows pay off?
At current energy prices in Europe, Passivhaus class windows are a high-ROI investment. The price difference compared to regular windows is recovered through reduced climate control costs. Additionally, such windows improve the property's energy efficiency rating, increasing its market value.
What sound insulation can be achieved with this system?
Thanks to the profile massiveness and the ability to install 56 mm glazing units, Cortizo A 84 is one of the quietest systems on the market. When using acoustic laminated glass, sound insulation reaches 48 dB, allowing complete isolation of a bedroom from airport or highway noise.
Can such heavy windows be installed in old buildings?
The sash weight with triple glazing can be significant. Before installation in older buildings, a specialist assessment of the opening condition is recommended. However, the A 84 system itself has the highest static rigidity and is designed for such loads, so the glass weight is not a problem for the window itself.
