Transparency is one of the main features of our aluminium enclosures and bi-fold sliding doors as a result of their large dimensions. Besides, once opened, the system only takes up 10% of the total space, which facilitates the installation of large doors and creates panoramic views.

Fully water- and airtight aluminium folding doors.

Our systems are manufactured with double, triple or quadruple sealing gaskets (depending on the series) specially designed to ensure greater watertightness and improve thermal performance.

Wide variety of openings.

Adjust the opening of your foldable sliding door system and use different panel combinations depending on the needs of the project.

Panels may be folded inwards, outwards, all to the right, all to the left or in the centre. Since the system offers multiple opening options, it is possible to decide to which side to fold the panels depending on the occasion.

The outer hinges are equipped with a removable pin, which makes it possible to detach the panels to clean the glass, even those areas that are difficult to reach.
