Why choose Avenir Renovations?
Why choose an aluminum window?
1. A sleek and modern design
Aluminum allows for the creation of thin and discreet frames, which let in maximum light. Ideal for large glass surfaces, sliding windows, or minimalist openings, it adapts to all architectural styles.
2. Great robustness
An unalterable material, aluminum does not rust, resists weather, UV, deformation, and requires very little maintenance. It is an ideal solution for large windows or buildings exposed to wind or humidity.
3. Excellent insulation performance
Today's aluminum joinery features thermal breaks that provide excellent energy performance. Combined with high-performance glazing, they meet the current energy performance requirements in Belgium.
4. A wide choice of finishes
Aluminum can be powder-coated in all RAL shades, with matte, satin, glossy, or textured finishes. It is also possible to choose a two-tone option (different color inside and outside).

Frequently Asked Questions – Aluminum Windows and Energy Renovation
Are aluminum windows compatible with energy renovation?
Yes. Contrary to popular belief, aluminum windows now offer excellent insulation performance thanks to integrated thermal break profiles. When combined with high-performance double or triple glazing (HR or HR+), they meet or even exceed the energy performance requirements in the context of a comprehensive energy renovation.
Can one benefit from grants or subsidies in Wallonia, Brussels, or Flanders for the installation of aluminum windows?
Yes, under certain conditions. As part of an energy renovation or improvement of the energy performance score, you may benefit from:
- regional energy grants or renovation grants
- cumulative bonuses if the windows are installed as part of a bundle of works (roof insulation, walls, heating...)
Conditions generally relate to:
- The Uw coefficient of the complete window (frame + glazing)
- The type of glazing (minimum double HR or triple)
- The intervention by a certified contractor
Avenir Rénovations Belgique assists you in checking your eligibility and in preparing the files.
How can one ensure that the installed aluminum window meets energy performance standards?
We only use certified aluminum joinery that is compliant with European standards (CE, EN 14351-1). Each window is delivered with:
- A complete technical data sheet
- A Uw performance certificate
- The mention of the type of glazing (Ug, solar factor, light transmission...)
These documents are necessary to prove the compliance of your installation for the energy performance declaration or when submitting a grant application.
What is the difference between renovation installation and total removal installation?
- Renovation installation involves retaining the existing frame (if in good condition) and installing the new window onto this frame. It is quicker and less invasive, but sometimes less effective in terms of sealing.
- Total removal involves completely removing the old joinery, including the frame, to install a new window with complete peripheral insulation. This is the method we prefer for a high-performance energy renovation, as it eliminates residual thermal bridges.
Can aluminum windows be combined with other insulation works?
Yes. Aluminum windows can be part of a coherent set of insulation works:
- Insulation of cavity walls or external insulation
- Insulation of the roof or attic
- Replacement of the front door
- Installation of insulating shutters or solar protections
These works can be coordinated in a comprehensive renovation plan to optimize regional grants, improve your energy performance score, and reduce your energy consumption.
