Exterior walls are all the walls that separate the inside and the outside of your home.

Exterior walls

Exterior walls are elevated after foundation and foundation walls have been laid and dried. These are in principle load-bearing walls, which constitute the skeleton of the house and are intended to support the roof. They can be built in poured concrete, blocks, bricks, or wood for timber frame houses.

There are different types of exterior walls, for example the sensor walls specifically adapted to bioclimatic houses to optimize solar heating.

Insulation of exterior walls

Exterior walls must be perfectly well insulated, in order to be protected from moisture. The insulation can be done from the outside by laying an insulation before dressing the facade. This powerful solution helps preserve the living space inside your home. In addition, by insulating your walls from the outside, you are entitled to financing assistance (tax credit, eco-loan at zero rate...).

The construction of new exterior walls

As part of the layout of your land, you may be brought to build a fence wall, in order to delimit your property, or a retaining wall if your terrain is sloping.

If you want to expand your home, you will have to make a declaration of work or apply for a building permit. You can build a wall without permission provided it does not exceed 2 meters high (depending on the PLU).

In any case, inquire at the town hall before starting work.

Exterior wall cladding

The outer walls of your house constitute the facade, which can be dressed and decorated in different ways. Coated, plastered, wooden cladding, zinc cladding, stone cladding: choose the option that seems most aesthetic and most suitable for the environment close to home. You will have to consult your town hall to know the regulations in force.
