Sliding glass doors in Cabo Negro
In Cabo Negro, large sliding doors open the villa onto the sea. On an exposed site, frame stiffness and wind tightness are decisive: we check them before pricing.
What we do in Cabo Negro
Large sliding doors that open the house onto the terrace, the garden or the sea, with very slim frames.
A sliding door replaces a section of wall with glass. The larger it is, the more the choice of system matters: frame stiffness, glazing, wind tightness. We offer minimalist systems (Strugal) and high-performance systems for exposed facades (Exlabesa).
What you gain
- Plenty of natural light
- Slim frames for an unobstructed view
- Systems suited to large dimensions and exposed facades
Technical details— for professionals and the curious
- Minimalist joinery
- Very slim profiles that reduce the visible part of the frame in favour of the glazing.
- Sliding with thermal break
- A sliding door whose frame includes an insulating strip, to better insulate against cold and heat.
- Profile inertia
- The stiffness of the profile against bending: essential so that a large opening doesn’t deform.

Why GMT Design in Cabo Negro
Cabo Negro is a headland on the Mediterranean coast, north of Martil, known for its villas and seafront residences. The site is exposed: wind, sea spray, strong sun. Joinery, glazing and balustrades there are chosen according to that exposure.
What we take into account in Cabo Negro
- Site exposed to wind and sea spray: calculated reinforcements
- Solar-control glazing for strong sun exposure
- Glass balustrades for terraces open to the coast
Frequently asked questions
How do I protect a large glass opening from sun and wind in Cabo Negro?
With solar-control glazing, a system with a thermal break (an insulating strip between the two faces of the frame) and sun protection (motorised roller shutters). The frame is reinforced according to the site’s exposure. We discuss it during the study.
What is the maximum width for a sliding door?
It depends on the system chosen and on wind exposure. We check feasibility during the study, before pricing.
Does a large glass door insulate against noise and heat?
Yes, provided the glazing and the system are well chosen. Acoustic laminated glass (two panes bonded around a noise-absorbing film) and a frame with a thermal break clearly improve comfort. We advise you according to the exposure of your home in Cabo Negro.
How much does a sliding door cost?
Ballpark: around 2,700 DH/m² incl. VAT installed for the Strugal S90P system, around 3,600 DH/m² incl. VAT for the S88RP with thermal break. Adjusted for configuration, glazing and site access.
Can it be installed as a renovation?
Yes, we also replace existing openings, including in occupied buildings.
