Aluminium windows in Asilah
In Asilah, the Atlantic air is salty all year round. We install aluminium windows treated against marine corrosion, suited to villas and second homes.
What we do in Asilah
Aluminium windows that close well, keep noise out and age well under salt and humidity.
We make aluminium windows and French windows in our workshop and install them: casement, tilt-and-turn or sliding, with double glazing. Each window is sized for its exposure: an upper floor facing the sea does not have the same needs as a ground floor on a courtyard.
What you gain
- Good air, water and wind tightness
- Low upkeep: aluminium doesn’t rot or swell

Why GMT Design in Asilah
Asilah is a small Atlantic coastal town south of Tangier. The air is salty all year round, and many houses are second homes: joinery that stands up to salt and needs little upkeep is a real advantage there.
What we take into account in Asilah
- Permanent salty air: marine-grade treatment and fixings
- Low upkeep for second homes
- Understated finishes, suited to the white architecture of the coast
Frequently asked questions
What upkeep does aluminium joinery need in Asilah?
Very little: rinsing with fresh water several times a year is generally enough to remove the salt, along with a gentle clean of the seals. Properly treated, aluminium rarely needs repainting.
Why choose aluminium for a window in Asilah?
Aluminium doesn’t rust, doesn’t rot and isn’t affected by humidity. With a treatment suited to the coast, it ages well under wind and salt, which matters in Asilah.
Do I need to provide plans?
No. Photos, a few dimensions or a simple description are enough to get started. If you have plans or a specification document (C.P.S.), attach them: it speeds up the study.
What does the quote include?
Detailed item-by-item pricing: manufacture, glazing, installation. Every line is explained, with no silent substitutions.
How much does an aluminium window cost?
It depends on the range, the glazing and the dimensions. As a ballpark, sliding doors in our Strugal range start at around 2,700 DH/m² incl. VAT installed; the final quote follows the study of your project.
