Installation and replacement of made-to-measure aluminium windows in Brussels (1000) and across the whole Brussels Region, from the Louise district to the European district. Ultra-slim profiles with a thermal break, large glazed bays and acoustic glazing against traffic — the aluminium that enhances upmarket apartments, lofts and penthouses, free survey within 48h and Renolution grants deducted.
We fit aluminium windows in Brussels with a team that knows the city and its contemporary architecture — from the upmarket apartments of the Louise district to the large-bay buildings of the European district, from the lofts of the Dansaert quarter to the penthouses of Châtelain and Flagey. Aluminium, with its ultra-slim profiles and thermal break, frees up the maximum glass area and light.
The survey is carried out at your home, with no call-out fee and scheduled within 48 hours ; the same team then follows the whole project, from taking measurements to fitting the large bays and the finishings, including planning-permission support and the choice of a RAL shade approved for protected zones.
We master Brussels buildings in aluminiumBeyond the Pentagon, we also fit aluminium windows in Ixelles, Saint-Gilles, Etterbeek, Uccle and Woluwe — same team, same lead times across the whole Brussels Region. For aluminium outside Brussels, see also our aluminium windows in Liège.
Brussels relies on the incentives of the Brussels-Capital Region, grouped under the Renolution grants. Aluminium with a thermal break and high-performance double or triple glazing is fully eligible. Here are the levers we handle and deduct directly from your invoice, with no advance on your part.
For the replacement of aluminium windows with a thermal break and high-performance double or triple glazing, the amount is graded by three income brackets and increased for low incomes. We calculate your bracket and handle the application.
For a home over 10 years old, VAT drops from 21 % to 6 % on the supply and installation of your aluminium windows. Applied directly to your quote.
In a listed or protected Brussels zone, a planning permit may be required : ultra-slim aluminium profiles adapt to contemporary requirements and we choose a RAL shade approved by the municipality, guiding you through the procedures.
The details of amounts, income brackets and conditions can be found on our window price & incentives page. We handle the entire Renolution application : you pay nothing upfront and you fill in no form.

From large-bay sliders to made-to-measure in a RAL shade, we tailor aluminium to your architecture and your budget. Explore each range :
Large sliding bays with slim profiles, ideal for opening a penthouse or an apartment in the Louise district onto its terrace without losing light.
Discover the sliders →The full RAL range, from matt anthracite grey to textured shades, to coordinate your windows with the façade of an upmarket building or a contemporary loft.
See the colours →Slim sections, full-height bays and special shapes manufactured to your measurements — for the extensions, lofts and large-bay buildings of Brussels.
Explore made-to-measure →Aluminium offers far slimmer profiles than PVC, so more glass area and light — a decisive advantage for upmarket apartments, lofts and penthouses in Brussels. It allows very large sliding bays that PVC cannot support, and its contemporary look suits the modern buildings of the Louise or European district. The thermal break ensures good insulating performance. If your priority is pure budget, see our PVC windows instead.
We schedule the survey at your home within 48 hours anywhere in the Brussels-Capital Region. The installation then depends on the made-to-measure manufacture of your aluminium windows, generally a few weeks ; the exact lead time is firmly confirmed as soon as the quote is signed. Distance within Brussels or its districts does not lengthen this lead time.
As Brussels falls under the Brussels-Capital Region, you benefit from the Renolution grants for the replacement of aluminium windows with a thermal break and high-performance double or triple glazing : the amount is graded by three income brackets and increased for low incomes. Add the 6 % VAT if your home is over ten years old. Note that these are not the Walloon grants. We handle and deduct these incentives ; all the amounts are detailed on our price & incentives page.
Yes. In the Pentagon, at the Sablon and in the protected zones subject to regional planning, replacing windows may require a permit. Ultra-slim aluminium profiles are precisely suited to contemporary requirements, and we choose a RAL shade approved by the municipality while keeping divisions consistent with the façade. We guide you through the planning procedures.
Yes, completely : the visit to your home in Brussels, taking the measurements and the costed quote for your aluminium windows are free and with no obligation. You pay nothing until you have approved your project.
