Why choose Avenir Renovations?
Why choose a wooden window today?
1. Exceptional natural thermal insulation
Wood is a naturally insulating material: it offers an excellent Uw coefficient, even without complex thermal bridge breaks. When combined with high-performance glazing (double or triple), it provides an effective thermal barrier against cold, drafts, and heat loss.
2. Timeless charm
Whether it is a farmhouse, a manor house, a stylish apartment, or a new construction with character, the wooden window adds character, nobility, and a warm atmosphere.
Available in oak, pine, meranti, exotic wood, or larch, it can be painted or stained in a myriad of colors.
3. Durable and repairable carpentry
Contrary to popular belief, a modern wooden window is deeply treated (IFH) against insects and moisture, and requires very little maintenance. It can also be sanded, repaired, or repainted, which significantly extends its lifespan.

Frequently Asked Questions – Wooden Windows and Energy Renovation
Are wooden windows effective for thermal insulation?
Yes. Wood is a highly efficient natural insulator, with a thermal conductivity coefficient lower than that of aluminum or PVC. A well-designed wooden window, equipped with double or triple glazing, offers excellent thermal performance (Uw ≤ 1.3 W/m².K), meeting the requirements of energy renovation in Belgium.
Can I receive a grant or assistance to replace my old windows with wood?
Yes. As part of a replacement of exterior joinery in an energy renovation project, the installation of wooden windows may qualify for:
- Renovation grants (Walloon Region)
- Energy grants (Wallonia, Brussels, Flanders)
- A PEB bonus if the work is part of a comprehensive package (insulation, ventilation, heating)
To benefit from these aids, the windows must meet certain technical criteria (Uw, type of glazing, CE certification) and be installed by a recognized professional.
Which type of wood is most suitable for energy renovation?
Treated pine, meranti, larch, or oak are commonly used species. Their thermal performance is excellent, and their behavior in relation to moisture is controlled through deep treatments (IFH). The choice will depend on:
- The window's exposure (north, rain, wind)
- The desired color or finish
- The budget
- Local urban planning regulations or architect's specifications
Does wood require a lot of maintenance?
Not necessarily. Current wooden windows are treated and pre-painted or pre-stained in the workshop. They withstand the test of time very well, provided that:
- Regularly clean the joinery
- Reapply a stain every 5 to 8 years depending on exposure
- Check the condition of seals and fittings
In terms of durability and the ability to be repaired or repainted, wood remains a sustainable and reversible option.
Does replacing wooden windows improve the PEB score?
Yes. Replacing old single-glazed windows with high-performance wooden windows (Uw ≤ 1.3 with double or triple glazing) can significantly improve:
- The PEB index of your home
- The resale value of the property
- The thermal comfort in winter and summer
The improvement is even more noticeable when combined with wall or roof insulation.
