The window contributes not only to the aesthetics of the house but also to the inhabitants' comfort by optimizing thermal and acoustic insulation. Whether in PVC, wood, or aluminum, tilt-turn or sliding, it can be equipped with different types of glazing depending on the needs.
Various materials are used in window manufacturing.
- PVC is currently the most common, with over 60% market share. It is appreciated for its ease of cleaning and installation.
- Wood is favored for its authenticity and aesthetics, but also for its insulation performance. Contrary to popular belief, it has great fire resistance.
- Aluminum is a lightweight material that is resistant to rust. Models made from this material are easy to install.
The choice of glazing depends on the room and its orientation:
- double or triple glazing is suitable for a north-facing opening to optimize thermal insulation;
- solar control glazing is suitable for a south-facing opening to reduce solar heat gains (especially in summer);
- acoustic glazing is recommended for an opening facing a noisy street;
- frosted glazing is advised for the bathroom to preserve privacy.
The type of opening should be adapted to the room:
- a French opening is suitable for both the living room and the bedroom;
- a tilt-and-turn model is an alternative in the bedroom for sleeping with the window open in summer;
- a sliding version is more suitable for a kitchen, especially for a window behind the sink;
- a sash model is also suitable for the kitchen.
Different options are available for the roof.
- The top-hung roof window (Velux) is equipped with a hinge at the top. It offers a clear view.
- The model with rotational opening is easy to maintain (cleaning the exterior glass). Moreover, the opening bar located at the top is difficult to reach for young children.
- The model with a lateral opening is comparable to a door opening outwards.
Replacing windows entitles you to various state aids:
- the energy transition tax credit (30%) if the installation is carried out by a certified RGE professional;
- the reduced VAT (5.5%),
- the energy bonus.
Thus, the choice of a window depends not only on the owner's preferences but also on the room and its orientation.
