In general, the improvement of accessibility and well-being allows a better comfort of use of the habitat. For openings, different technical solutions to improve accessibility exist. They consist in particular to act on the height of lighter (reduced threshold or integrated threshold) or to use accessories (motorization of the command, use of an operating rod …) some of these equipment’s, may be eligible for the credit of tax (assistance to the person).
The main materials for windows
Whether wood, PVC, aluminum or even mixed, joinery each have their advantages. Highly efficient, wooden windows require regular maintenance. The aluminum profiles are unalterable and offered in a wide range of colors. Economic and insulating, PVC is the most popular material in renovation. Mixed windows offer very good thermal insulation and require little maintenance.
The evolution of the window market, growing by 5% per year, benefits mainly PVC even if the aluminum window, long reserved for the tertiary sector, makes a remarkable breakthrough on the retail market, almost at the same level as the window in wood, big loser of this evolution.

Traditional material abandoned in recent years in favor of maintenance-free materials. However, in adapted species (exotic wood for example) wood can be sustainable (several decades) with regular maintenance. In addition to its insulating and aesthetic qualities, wood is more energy efficient than aluminum. It is easily renovated, sanded, planed and painted to find a new youth.
The most used in the new and existing (60% of market share in the existing), it enjoys several advantages:
- Performance / price ratio;
- High mechanical resistance thanks to the insertion of metal reinforcements in the heart of the profiles;
- Many possibilities of form to integrate with all styles;
- Customization possible with a large choice of rounded, stylized and biased profiles;
- Multiple finishes: white is the most common. But there are now colored PVC (stained in the mass), lacquered (surface spray) or PVC “plax” (reported finish). Maintenance is often limited to an annual cleaning.
We find the advantages of durability, ease of maintenance, finishing (many colors) with in addition the increased mechanical strength of the material, which makes it possible to reduce the section of the profiles (light section) to gain brightness and aesthetics (fineness of the profiles). Rigid and resistant, aluminum windows are often preferred on large openings (windows , verandas) to support increasingly heavy glazing (sound glazing).
It is chemically inert, does not emit VOC, incombustible, insensitive to climatic variations and, now essential criterion, it recycles itself to infinity (without loss of its properties).
Technique that involves associating on a carpentry, 2 different materials to enjoy their respective advantages. This is why there are interior wood joinery associated with aluminum for the outside. This is the most expensive of the 4 solutions.
Beware, some municipalities limit the choice of materials. Subdivision or co-ownership rules also prohibit the use of certain materials, including PVC. It is therefore good to learn about the rules in force.
Change your windows: for which opening system to opt for?
Sliding, swinging, US … The windows offer opening systems more and more varied. The desired effect and obtained-enlarge the space, let in the light-will not be the same depending on the models.
Us overture: the classic
This is the reference window. Opening inwards by pivoting laterally on hinges, the US window allows full opening and offers a wide range of locking systems.
The plus: Optimum sealing, easy maintenance, great adaptability to all types of shutters (rolling or flying).
The least: The opening inward logically encroaches on the space of the room. To proscribe in the confined spaces (studios, bathrooms).
For which parts? Leaving the light, it is ideal in living areas and rooms of consistent size.
Sliding window (conventional or pocket-style): the space saving option
This increasingly popular model opens by sliding along a rail embedded in a frame. In the classic option, the two windows slide parallel one behind the other. For the pocket window, the two leaves disappear in a frame integrated with the bulkhead.
Plus: The “sliding” can open gradually without slam and offer an undeniable saving of space. Once opened, the window does not encroach on the interior space.
The least: More difficult maintenance and partial opening for classic sliding models. Sliding sliding, they, allow full opening but their installation may require work a little heavier to integrate the frame in the wall.
For which parts? All types of rooms. Ideal solution in small spaces
Bellow or tilt-turn window: ventilate first
The flap window opens about 15 cm horizontally, upwards. The tilt-and-turn model combines the oscillating opening system and the window film privacy (lateral opening). Both systems are ideal for dealing with room ventilation problems.
The plus: These two windows can stay open even in case of rain. Their small cracking provides optimum safety for children. The tilt-and-turn model is the most complete on the market.
The least: Its reduced opening (for classic models) is problematic in living rooms. Tilt-and-turn models can be difficult to handle depending on the quality.
For which parts? The rooms dark and poorly ventilated, a cellar, a basement, or high in some bathrooms.
Italian opening: above a sink or worktop
This type of window also opens horizontally, but downwards. It offers the same advantages as casement windows in terms of ventilation and window film privacy.
Most: Its opening to the outside cannot clutter the space below and it is available in very large format.
The least: Its reduced opening, is limited to 10 cm.
For which parts? Ideal in the kitchen, it can ventilate and find its place above a sink or a worktop.
