Where to start?
One project, two ways to talk about it.
I’m building or renovating my home
Windows, sliding glass doors, balustrades, verandas: we explain things simply and price them clearly. No technical specification required.
- A description or a few photos are enough to get started
- A detailed quote, item by item
- Made in our workshop and installed by our own teams
I have an architect, developer or hotel project
We review your C.P.S. (project specification) line by line and send you a proposal that complies with it, technical data sheets included.
- C.P.S. and AEV rating check before pricing
- Strugal, Exlabesa and Comfort systems, with technical data sheets
- Site follow-up through to snagging (final defect correction)
Our commitments
Three commitments, one standard.

What’s promised is what’s delivered
No unpleasant surprises at handover: every thickness, every brand and every performance figure matches what was specified, line by line.
Compliance engineering — thicknesses, inertia values (profile stiffness) and brands as per the specification (C.P.S.)

Built for wind, salt and humidity
Northern Morocco is demanding: east wind, salty air, humidity all year round. Our profiles (the aluminium frames) get a marine anti-corrosion treatment, reinforcements are calculated for the wind and the fixings don’t rust.
Qualicoat Seaside · Zone 3 reinforcements · A4 stainless fixings

A finish you can see, and that lasts
Corners are assembled in the workshop, the seals hold up to the sun better than silicone, and the site is protected until handover.
