Insulation work in Brussels (1000) and across the whole Brussels Region: loft and roof, walls, floor and façade. A Brussels team, a free technical survey at your home scheduled within 48h and the Renolution subsidies arranged and deducted for you — from the grand townhouses of the upper town to the listed façades of the centre, where insulating from the inside preserves the building.
We insulate homes in Brussels with a team that knows the city — from the Pentagon and the Grand-Place to the districts of the upper town, from the Sablon to Laeken, taking in the grand townhouses with gable roofs and the buildings with flat roofs.
The technical survey is done at your home, with no call-out charge and scheduled within 48 hours ; we measure heat loss, check the condition of the building and cost the right insulation jobs. On a listed façade or in a protected zone, we favour insulating from the inside to preserve the exterior appearance, and the same team then follows the whole project through to the finishing touches.
We know the Brussels building stockBeyond the Pentagon, we also insulate homes in Ixelles, Saint-Gilles, Etterbeek and Laeken, as well as your loft, your walls and your façade — the same team, the same lead times across the whole Brussels Region.
Brussels relies on subsidies from the Brussels-Capital Region, grouped under the Renolution subsidies. Here are the levers we arrange and deduct directly from your bill, with nothing for you to pay up front.
For insulating the roof, walls and floor, the amount is scaled according to three income brackets and calculated per square metre insulated. The subsidy is increased for modest incomes — we calculate your bracket and build the complete file.
For a home over 10 years old, VAT drops from 21% to 6% on the supply and installation of the insulation. Applied directly on your quote.
Depending on your project, an energy audit may condition or increase the subsidy: we arrange it if necessary, then build the entire Renolution file for you.
The detail of the amounts, income brackets and conditions is on our insulation price & subsidies page. We build the entire Renolution file : you pay nothing up front and fill in no forms.
A few recent projects in Brussels and its districts. Every project is handled by the same team, from the technical survey to the finish.
Roof rafters insulated under the pitch and blown-in loft insulation, with no work whatsoever on the listed façade. The top-floor heating bill dropped sharply from the following winter.
Voir le chantier →Protected façade preserved: wall insulation from the inside with a vapour barrier and plasterboard finish, room layouts respected. Thermal comfort regained without altering the exterior.
Voir le chantier →Blown-in cellulose loft insulation, in a single day and with no roof dismantling. Renolution subsidy calculated according to the income bracket and deducted from the bill.

« Isolation de la toiture et des combles. Différence ressentie dès l'hiver suivant. Petit retard de planning, mais résultat à la hauteur. »
« Insufflation des murs creux, rapide et sans dégât. La prime régionale a couvert une bonne part. Maison nettement moins froide. »
From the roof that weighs most on the bill to the walls and the façade, we adapt the work to the building, the planning rules and the budget. Discover each job :
The most cost-effective job on Brussels homes: blown-in loft insulation or sloping rafters insulated under the pitch, with no work on the façade. Immediate saving on the heating bill.
Discover →From the inside when the façade is listed or protected, from the outside when planning rules allow. We remove the cold walls of terraced houses while respecting the character.
See →External façade insulation (EWI) with a render or cladding finish where Brussels planning rules allow: maximum performance and a renovated façade in one move.
Explore →You almost always start with the roof and loft: it’s the most heat-losing and the most cost-effective job. During the free technical survey at your home, we measure heat loss, check the condition of the building and propose a costed order of priority (roof, walls, floor, façade) suited to your budget and the available subsidies.
As Brussels comes under the Brussels-Capital Region, you benefit from the Renolution subsidies for insulating the roof, walls and floor: the amount is calculated per square metre insulated, scaled according to three income brackets and increased for modest incomes. On top of that is 6% VAT if your home is over ten years old. Note that these are not the Walloon subsidies. We arrange and deduct these subsidies; all the amounts are detailed on our price & subsidies page.
Not always: for a simple job like loft insulation, it’s generally not required. However, for a broader renovation or to increase certain Renolution subsidies, an audit may be requested or recommended. We tell you clearly during the survey and arrange it if necessary before building your file.
It depends on the job: blown-in loft insulation is often done in a single day, while wall insulation from the inside or external façade insulation takes from a few days to two weeks depending on the surface area. The exact lead time is firmly confirmed when you sign the quote, with a single team from start to finish.
Yes, completely: the call-out to your home in Brussels, the heat-loss diagnosis and the costed quote are free and with no obligation. You pay nothing until you have validated your insulation project.
