Sliding windows and patio doors
The way to step out onto the terrace or close a wide opening without sashes taking up space. In aluminium or PVC, made to measure.
A sliding system for every opening
- 2, 3 or 4 panels, with fixed side panes if needed.
- Thermally broken aluminium for wide openings and slim frames, in any RAL colour.
- PVC when insulation matters most.
- Key lock or flush lock on the panel.
- Sliding insect screen built into the same frame.
Want to enclose the whole terrace without vertical profiles? See glass curtains.

Questions about sliding windows
Sliding or casement?
A sliding window takes no room when open and is ideal for terrace exits; a casement seals a little tighter. Many homes combine both.
How big can it be?
It depends on the system and the weight of the glass. In aluminium we make very large sliding doors; we confirm the solution when we measure.
