Green insulation

Unlike glass wool for example, which is harmful to lungs during laying and removing, green insulation is respectful of both the environment and human health. Made from vegetable or animal fibres, or renewable materials, they are gradually becoming more popular. An overview of the different insulating materia

Hemp

Made from plant fibres, it is the most well known green insulation. Naturally resistant to insects and mould, permeable to vapour, it is sold in the form of panels, in rolls, or in bulk.

Wood wool

Good thermal and sound insulation, wood wool panels, originally from sustainably managed forests, are perfect for roofs, walls, and ceilings.

Cork

Because it is filled with air, cork is a very good thermal insulating material. Light, rot-proof, able to withstand humidity without deforming, it is also effective against vibrations and efficiently reduces noise. Made from a slow-growing species (the cork-oak), its cost is higher than other insulating materials.

Sheep wool

Very good insulation, the fibres must undergo an anti-mite treatment with Mitin, a non-toxic product. Light, it can absorb 30% of its weight in water.

Cotton wool

Non-ageing, cotton wool is generally made from recycled cotton. It is good for thermal insulation because of its ability to store air. It must be treated with borax to resist insects and mould.

Coconut fibre

Good used in floors for sound insulation, it’s recyclable, makes a good thermal break, and is moisture-proof.

Flax

Good acoustic insulating material, it must however be treated with borax to resist insects, mould, and fire.

Duck feathers

Sold in panels and rolls, duck feathers can absorb up to 70% of their weight in water while keeping their insulating power. A treatment against mites and dust mites is necessary. Quite flammable (class C), this insulation can be quite allergenic.

Straw

Unlike hay, straw does not decompose. It therefore has good durability over time if it is not subjected to humidity. Bales are used to fill walls with woodwork constructions and are protected by a vapour barrier covered with lime plaster or siding.

Cellulose wadding

Manufactured from old newspapers, cellulose wadding is laid in panels. In addition to its thermal properties, it is also a good acoustic insulation. The insulation must be treated against insects, fungi, and to improve its performance in terms of fire (borax).
