Buildings in Rosières
Tailored to the buildings of Rosières, after an on-site survey. No obligation.
Rosières is one of the three sections of Rixensart, in the Lasne valley. More modest and more working-class than Genval and its lakeside villas, it keeps the traces of a more artisanal and industrial past, around its station (RER) and the watercourse.
The building stock mixes old workers’ and bourgeois houses, villas and more recent detached houses. Replacing windows here meets varied needs: giving character back to an old façade, or bringing comfort and insulation to a family home.
Along the railway and the main road, acoustic insulation matters; on the hillsides and towards the valley, the districts are quiet and green.
We work throughout the municipality — for example
- Rosières centre
- Lasne valley
- Hillsides
- Near the station
- Bois de Rosières
Which windows, which glazing for your street
Old house of character
Timber or slim-profile aluminium, respecting the character.
Near the railway or the main road
Acoustic glazing and airtight windows for a quiet interior.
Residential family home
PVC or aluminium with high-performance double glazing, for insulation and low maintenance.

Windows in Rosières: your questions
Do you install windows in Rosières?
Yes. Pulsar Windows designs, replaces and installs custom windows, entrance doors and sliding doors in Rosières (Walloon Brabant) and the neighbouring municipalities, with support in both French and English.
PVC, aluminium or wood: which material should you choose in Rosières?
PVC offers the best value for money and high insulation; aluminium, with its slim profiles, is ideal for large bays and sliding doors; wood brings warmth and character. During a free on-site measurement, we advise you on the solution best suited to your building and your budget.
How much does window replacement cost in Rosières?
As each project is made to measure (dimensions, material, type of glazing, finishes), the price is set after a free on-site measurement. You then receive a detailed, clear and no-obligation quote.
Can I get a grant for my windows in Rosières?
Rosières comes under Walloon Brabant. The Prime Habitation is still open under a temporary scheme, but an audit by an accredited auditor is a compulsory prerequisite, and the works cannot start before their visit. Every application, final invoice included, must be submitted by 30 September 2026 at the latest. A new scheme takes effect on 1 October 2026. High-performance joinery required: Uw ≤ 1.50 W/m²K and Ug ≤ 1.10 W/m²K. Checked on 29 August 2026; the full region-by-region picture is on our Grants & subsidies page.
Do you need major work to replace windows?
In most cases, we work in renovation mode: careful removal of the old windows and installation of new ones with interior and exterior finishes, without major masonry work.
