Why choose Avenir Renovations?
What types of insulation work do we carry out in Brussels?
In Brussels, buildings are often terraced, partially buried, or subject to specific urban regulations. This requires a personalized approach for each insulation project. For example, in certain classified areas or visible from public space, external insulation may require permission. We integrate these constraints from the design phase to offer you effective, compliant, and sustainable solutions.
We work on all elements of the building envelope, both new and renovated:
- Roof insulation or attic insulation (from the inside or outside)
- Wall insulation (from the inside, outside, or in the cavity)
- Floor insulation (ventilated crawl space, basement slab, hollow core)
- Insulation of basement or garage ceilings
- Replacement of low-performance frames (high-performance triple or double glazing)
- Acoustic insulation between apartments, floors, or rooms
- Renovation of thermal bridges and uninsulated areas
- Installation of suitable controlled ventilation (simple or double flow VMC)
We use materials that comply with PEB standards and the constraints of the building: mineral wool, cellulose, sprayed PUR foam, rigid PIR panels, wood fibers, expanded cork... We help you make the right choice between performance, cost, durability, and eligibility for grants.

We help you plan the work according to the requirements of the Energy Performance Certificate, available aids, and housing occupancy constraints. If you are in a co-ownership, we prepare a technical file to submit to the property manager.
