A folding sliding system opens the entire aperture without leaving anything behind. Panels fold like an accordion and push to the side — not a single fixed section blocks the passage. The interior and terrace become one unified space.
Available exclusively in ALU, with 2 to 6 or more panels, in single-row and corner configurations. ALU systems are chosen for their greater stability, durability and reliability in everyday use, while PVC variants have not proved sufficiently effective for this type of opening. Every system is made to measure for the specific opening and architectural requirement.
Available in PVC and aluminium versions, with various panel counts and folding configurations. Every model is adapted to the opening dimensions and building requirements.
A folding system works by moving multiple interconnected panels along guides that fold one against the other. When opening, the panels slide and overlap to the side, creating an almost completely open passage with no fixed elements obstructing the space.
The system uses precision ALU profiles, hinges and sliding mechanisms that allow easy and quiet panel movement. It is ideal for large openings because it connects the interior and exterior into one whole, with maximum natural light penetration and a modern appearance.
A door or balcony passage can be integrated within the folding system, allowing easy access to the terrace even when the system is fully closed.
From compact two-panel systems to corner configurations spanning entire walls — there is a solution for every opening.
Two panels that fold alongside each other. Suited to smaller openings up to ~2.4 m. Minimal stacking space required — ideal when there is no room to slide sideways.
Three panels — one fixed and two that fold. Openings from 2.5 to 4 metres wide. The most commonly used system for house terraces and garden access.
Four, five or six panels on a single track. Openings of 10 metres and more. All panels fold to one or both sides — opening the entire wall with nothing remaining.
A system that wraps around the corner of a room. Two rows of panels that meet at the corner and fully open two sides simultaneously. A dramatic spatial effect.
PVC profiles with thermal chambers. A more accessible price with good thermal insulation. White and film-wrap finish. Suited to residential terraces and winter gardens of standard dimensions.
Aluminium slim-line profiles with thermally broken chambers. Slim, elegant, available in all RAL colours. Capable of carrying larger and heavier panels. The standard for luxury and commercial buildings.
A folding system offers something no other system can — complete opening of the entire aperture with nothing remaining, combined with maximum flexibility in everyday use.
All panels fold and push to one side — the opening is 100% clear, with no fixed section left behind. The interior and terrace merge into a single space.
Unlike sliding systems, folding doors do not require wall space for panels to slide into. Panels fold onto each other and occupy only the width of the stacked pack.
It is possible to open just part of the system — one or two panels — for ventilation while leaving the rest closed. Each panel can be stopped in any position.
With ALU profiles featuring thermally broken chambers and double or triple glazing, folding systems achieve U-values suitable even for passive-house construction.
The top track carries the entire system — there is no bottom track to impede passage. The floor is smooth and obstacle-free, making the indoor–outdoor transition completely unhindered.
Dimensions, number of panels, folding direction (left, right or both ways), glass type and profile colour — everything is adapted to the specific opening and architectural requirements.
Wherever the entire opening needs to be fully clear — without a remainder, without obstruction, without compromise.
The most common application. The entire wall opens towards the garden or terrace — no obstruction, no threshold, no fixed section remaining.
The ideal system for hospitality venues that want to open their terrace in good weather — fully merging the interior and outdoor space.
Fully open in summer, closed and thermally insulated in winter. A flexible year-round space that adapts to the season.
Internal folding partitions for dividing offices, meeting rooms and multi-purpose spaces. Flexible and without permanent walls.
