Why choose Avenir Renovations?
Our glass wall installation services in Brussels
We operate throughout the Brussels-Capital Region for the installation, replacement, or creation of glass walls, whether in a house, an apartment, or a collective building.
Sliding glass walls
Ideal for optimizing space, sliding glass walls allow for a smooth opening to the outside. We install:
- aluminum, PVC, or wood-aluminum frames,
- double or triple glazing (Ug ≤ 1.1 W/m²K),
- recessed or visible tracks depending on your floor,
- models with 2, 3, or 4 leaves, up to 6 meters wide.
Pocket glass walls
For a completely unobstructed effect, the leaves disappear into the walls. This system requires specific preparation but offers a high-end finish. We carry out this type of installation in new builds or renovations if the configuration allows.
Creation or transformation of openings
We can transform an old French door or a wall facade into a glass wall, after a technical study:
- checking the structure,
- possible reinforcement of the lintel,
- implementation of watertight and insulated thresholds.
The 5 steps of a sliding glass door project with Avenir Rénovations
With Avenir Rénovations, the installation of your sliding glass door follows 5 steps: technical study, model selection, clear quote, careful installation, and final inspection with guarantees and support.
Why hire a professional to install a bay window in Brussels?
Hiring a professional in Brussels ensures a bay window installation that complies with thermal and acoustic standards, respects urban planning constraints, and guarantees an aesthetic, durable, and value-adding result for your property.
In Brussels, to benefit from aids or improve your energy performance certificate (PEB), it is essential to meet technical thresholds. A professional will choose the right materials and ensure an installation without thermal bridges.
On the facade, creating or modifying an opening may require urban planning authorization. Avenir Rénovations assists you in compiling the file and ensures the compliance of materials and colors.
A poorly installed bay window that rubs, condenses, or lets air through degrades the comfort and value of the property. Our team guarantees a careful, functional, and durable installation.

Why choose Avenir Rénovations for your glass walls in Brussels?
In Brussels, glass wall projects must combine aesthetics, insulation, security, and sometimes compliance with urban planning regulations. Our team offers you:
- a technical study on site,
- certified Belgian or European joinery,
- installation carried out by qualified craftsmen,
- compliance with PEB requirements and Uw/Ug thresholds for grants,
- possible coordination with other trades (terrace, shutters, blinds...).
We also help you prepare the documents to present to your municipality or your co-ownership in case of facade modification.
Concrete example of a glass wall project in Brussels
Mr. and Mrs. Claes live in a three-facade house in Jette. They wanted to replace two old wooden French doors with a large sliding glass wall to open their living room onto the southwest-facing terrace.
We proposed a matte black aluminum sliding glass wall with 3 leaves, featuring safety laminated glazing. The walls were slightly modified to integrate the new threshold, with thermal insulation and thermal bridge breakage.
- Glazing area: 6 m²
- Total amount (supply + installation): €5,100 VAT included
- Category R2: grant of €624 (€104/m²)
Work completed in two days, including interior finishes. The couple now enjoys a space filled with light and improved energy efficiency.
What you need to know before installing a glass wall in Brussels
Do I need a permit?
Yes, if you are creating a new opening or if the facade is visible from the street. For a simple like-for-like replacement, the declaration is not mandatory. In case of doubt, we help you verify.
Are glass walls eligible for energy grants?
Yes, if you meet the technical conditions (Uw ≤ 1.5 / Ug ≤ 1.1) and if you are replacing an old joinery. The installation must be carried out by a professional and invoiced in your name.
What is the difference between sliding and pocket?
The sliding glass wall leaves part of the glazing in the open position. The pocket system slides the leaves inside the wall for a total opening. The latter requires more work but offers a higher-end finish.
Do I need to reinforce the wall to install a glass wall?
Yes, in some cases (transformation of a load-bearing wall, increasing the width). Our teams assess the situation and plan the necessary reinforcements according to best practices.
