Aluminium joinery in Martil
Beachfront flat or holiday home in Martil: we make and install aluminium doors, windows and sliding doors, with little upkeep.
What we do in Martil
Aluminium windows, French windows, sliding doors and shutters, made in the workshop and installed by a single team.
Aluminium joinery covers all the openings of a building: windows, French windows, sliding doors, shutters. We help you choose between three profile ranges (Comfort/Triana for a controlled budget, Strugal for minimalist design, Exlabesa for very high performance), then we make and install.
What you gain
- One point of contact, from study to installation
- Profiles chosen for your budget and your exposure
- A final check with immediate correction of defects
Technical details— for professionals and the curious
- Profile range
- The profile is the aluminium structure of the frame. The range determines its slimness, its insulation and its price.
- Thermal break
- An insulating strip between the two faces of the profile stops cold and heat passing through the metal.
- Inertia
- The stiffness of the profile against bending: the higher it is, the better a large opening holds without deforming.

Why GMT Design in Martil
Martil is a seaside resort on the Mediterranean coast, close to Tetouan. Sand, sea spray and humidity quickly wear out unsuitable joinery; many homes are holiday residences or seafront flats.
What we take into account in Martil
- Sand, sea spray and humidity: marine-grade materials
- Low upkeep for homes that are occupied on and off
- Sliding doors and glass balustrades for sea views
Frequently asked questions
Does aluminium joinery stand up to sand and sea spray in Martil?
Yes, provided it has a suitable treatment (marine-grade powder coating), A4 stainless fixings and quality seals. Regular rinsing with fresh water extends its life.
Which range should I choose?
Comfort/Triana suits a controlled residential budget; Strugal offers high-end minimalist design; Exlabesa targets very high performance (hotels, seafront). We advise you according to your project.
Do you make joinery to measure?
Yes, every piece of joinery is made in the workshop to the dimensions of your openings.
Do you work in Martil?
Yes. GMT Design works in Martil and across Northern Morocco: Tangier, Tetouan, Al Hoceima, Asilah, Martil and Cabo Negro.
What are the lead times?
They depend on the size of the project and the range chosen; they are specified in the proposal.
