New minimalist window A 84 hidden sheet by Cortizo

 In Enclosures

In DISPER we work and we have a wide range of products for any construction requirement with the maximum performance and guarantees. Systems with great thermal and acoustic performance, designs that guarantee maximum luminosity, solutions for large dimensions. 


An unlimited choice guaranteed by Cortizo. We have different materials available to ensure that your project acquires the aesthetics you are looking for

One of our main tasks is to provide our best advice to our customers when deciding on the details of their home’s carpentry. We are aware that it is usually difficult to decide on one material or the other, so the guidance we can provide is very helpful. Among our materials you will be able to choose aluminio or PVC, both with great features.

To continue with our mission, we present the new A84 Hidden Sheet (HO) series, a new generation system in PVC which offers the best insulation on the market.

A minimalist window with a visible section of only 90 mm that also offers the possibility of a reduced central junction, which allows for the maximisation of the glass surface and the entry of natural light into the spaces where it is installed. 

This 84-mm deep system with 6 internal chambers combines its elegant design with excellent thermal performance, reaching a Uw transmittance value of 0.74 W/m²K. 

These features are even improved in its Passivhaus version certified for the warm-temperate category, which has a Uw value from only 0.71 W/m²K, making it an ideal solution for low energy consumption buildings in areas with warm and temperate climates, such as Spain. 

The new A 84 Cortizo PVC concealed leaf has a maximum glazing capacity of 46.5 mm, allowing triple glazing to be installed and exceptional acoustic insulation of up to 46 dB.

All these features are reinforced by the great results achieved on the AEV test benches: Class 4 in air permeability, Class E2100 in water tightness and Class C5 in wind resistance. 

As with the entire Cortizo PVC range, the new A 84 Hidden Leaf also stands out for the quality of its profiles: CLASS A (3 mm thick main walls), CLASS S (suitable for severe climates; optimum performance in terms of solar incidence) and CLASS II (maximum impact resistance).

The A 84 Hidden Leaf system has an elegant straight-line aesthetic and is available in a wide range of finishes in white, colour, two-tone, wood imitation and metallic. It is available for both windows and balconies, with maximum dimensions per sash of 1400 mm wide and 2500 mm high, weighing up to 130 kilos per sash, and the possibility of opening the inside, whether it is openable, tilt and turn, tilt and turn or folding
