Aluminium for Liège’s large openings : ultra-slim profiles, full-height glazed bays and a thermal break, from the Guillemins to the heights of Cointe. A local team, a free site survey scheduled within 48h and the Walloon grants arranged and deducted — from the Meuse quayside to the contemporary extension.
We install aluminium windows in Liège with a team that knows the city — from the Calatrava station at the Guillemins to the Meuse-valley houses of Outremeuse, from the slopes of Cointe with their valley views to the Meuse quays. Aluminium, with its slim profiles and thermal break, is the material of large bays and contemporary style.
The survey is carried out at your home, with no call-out fee and scheduled within 48 hours ; the same team then sees the whole project through, from measuring up to fitting the bays and finishing.
Liège buildings in aluminiumBeyond Liège itself, we also install aluminium windows in Seraing, Herstal, Ans, Chaudfontaine and Visé, as well as towards Verviers and Namur — same team, same lead times across the province.
Liège falls under the grants of Wallonia. Thermally broken aluminium with high-performance glazing opens up the same levers, which we arrange and deduct directly from your bill, with nothing to pay up front.
For replacing windows with high-performance glazing, scaled to your income. Thermally broken aluminium profiles meet the performance requirements. A housing audit is required above a certain amount — we point you to an accredited auditor.
For a home more than 10 years old, VAT drops from 21% to 6% on the supply and installation of the aluminium windows. Applied directly to your quote.
The City of Liège does not add a specific window grant on top of the regional support ; certain urban renewal perimeters may, however, open up additional assistance. We check your address on a case-by-case basis.
The detail of amounts, conditions and income ceilings is on our window prices & grants page. We handle the entire file : you pay nothing up front and fill in no forms.

From large sliding bays to bespoke RAL shades, we tailor aluminium to the building and the style. Explore each aluminium range :
Large slim-profile sliding bays to open onto the garden, courtyard or valley. Ideal for the extensions and villas of the Liège heights.
Discover the slider →Unlimited RAL shades, from contemporary anthracite to structured tones. Perfect for contrasting with Meuse-valley brick or matching a design façade.
See the colours →Panoramic fixed panes, special shapes and very large glazed surfaces. The rigidity of aluminium allows slim frames where PVC is no longer enough.
Explore bespoke →Aluminium stands out for its ultra-slim profiles, which maximise the glazed surface and the light : it is the ideal material for large bays, extensions and architect-designed houses. Its rigidity allows slim frames where PVC becomes too thick, and the RAL shades (anthracite above all) give it a contemporary look that is much in demand in Liège. It is also the choice of durability and style on the hillside villas of Cointe or Sainte-Walburge.
Yes, provided you use thermally broken profiles, which we fit as standard. An insulating strip separates the inside of the frame from the outside and cuts the transfer of cold, which lets aluminium reach excellent performance with double or triple glazing. Combined with large south-facing glazed surfaces, it brings a real gain in comfort and solar input on the Liège slopes.
As Liège falls under Wallonia, thermally broken aluminium with high-performance glazing qualifies for the Habitation grant for replacing windows (scaled to your income) and for 6% VAT if your home is more than ten years old. The City of Liège does not add a specific municipal window grant. We arrange and deduct this support ; all amounts are detailed on our prices & grants page.
Absolutely — it is one of our favourite types of project in Liège. On the brick of Outremeuse or Saint-Léonard, slim-profile anthracite aluminium creates an elegant contemporary contrast while respecting the proportions of the original openings. For façades visible from the street in certain perimeters, we choose shades approved by the planning authority and guide you through any procedures.
