The walls must be solid. Certainly, but it is no longer sufficient. With ecological awareness and rising energy prices, walls must be insulating. While keeping their aesthetics.

Walls: different materials

In France, the walls of houses are built from four main materials: stone, concrete block, cellular concrete and wood. If you want to give character to your home, stone is the ideal choice. Attention, the town hall can impose a type of materials in order to harmonize the aesthetics of its streets.

Walls: the insulating character

The denser and heavier the material, the more the wall will act as insulation. Dense wood or solid bricks are the best examples. The stone walls, on the contrary, let the heat through because the mortar which serves as a joint is very porous. Regarding the concrete block wall, it must be accompanied by a counter-partition to ensure good thermal insulation.

Walls: additional insulation

Unless you choose solid brick or solid wood, you will need to use additional insulation with the installation of your walls. Glass wool has long been the ultimate insulator. But its irritant nature causes itching during the pose. As a result, amateurs and professionals are increasingly turning to more natural materials. In this category, sheep's wool is certainly the cheapest insulation (€ 12 / m² for 100 mm thick). It is a very good thermal and sound insulator. Hemp wool also offers very good insulation results. In addition, it is a natural antifungal.
