The sliding glass door is the strongest gesture of a renovation: a wall becomes a view. With a 20 mm interlock, an invisible threshold and sashes that vanish into the wall, ours leaves almost nothing between you and the garden.
01What makes the difference
It is all in the details you no longer see.
- 20 mm interlock: only 2 cm of aluminium where the sashes meet.
- Invisible threshold: the rail is recessed, terrace and living room floors continue without a step.
- Pocket sliding: the sash slides fully into the wall.
- Hidden rollers and drainage.
- Sashes up to 3 m high, sliding with one finger.
02Comfort and performance
Double or triple solar-control glazing, thermally broken profiles, triple seals: it insulates from cold and noise, and laminated glass meets safety requirements.
03In renovation
Replacing a small opening with a large sliding door often means enlarging the opening and re-doing the lintel. We coordinate these works with our specialists so you have one point of contact. See the Ellie project.
04Sliding patio doors, pocket sliders, corner sliders: the formats
Sliding glass doors come in every format: two-sash patio door, three- or four-track aluminium slider, pocket slider vanishing into the wall, 90-degree corner slider without a post, or motorised sets for very large sashes. The system we install most is Cortizo's COR Vision Plus: 20 mm interlock, recessed threshold, hidden rollers and drainage.

Yes, provided it is planned from the design stage: a shutter box or external solar screen fits in the lintel, and a discreet sliding insect screen can be fitted on the track.
Laminated glazing, multi-point locking and profiles sized for wind load: safety and weather tightness are tested and certified, just as on a quality conventional window.
