What are the different thermal insulation technologies of eco-housing?

Published on : 29 April 20202 min reading time

The eco-habitats act under the respect of the environment. They have been established according to a concept that limits the greenhouse effect and reduces carbon dioxide emissions. Eco-homes also have a performance aimed at reducing energy consumption. In particular, there are several variations on the thermal insulation technology of an eco-home.

Artificial Vitreous Fibres

Artificial Vitreous Fibres (AVF) are of mineral origin. They are used for the insulation of an ecological house. These fibres are to be combined with other materials to optimise the sound and acoustic insulation of a house. Among the best known FVAs are wools. These show good thermal insulation. In addition, they make it possible to fight against asbestos, which is responsible for several pathologies, in particular lung cancer. Glass wool has the advantage of being lighter. However, it is no more efficient than rock wool in terms of heat retention when temperatures tend to drop in winter. In fact, rock wool is known for its high resistance to fire.


Straw is also an effective solution that helps reduce energy losses. It has a better quality of insulation. Straw can be inserted directly into the walls of a house. Lavender straw, in particular, is intended for attic insulation or as a filling for wooden frames. When combined with air lime, straw concrete provides better thermal and mechanical performance. It is effective in terms of thermoregulation of the walls of new or old buildings. Lavender straw, due to its natural properties, is also an excellent insecticide. It is often found in plastic bags at various suppliers.


Among the various materials that allow energy saving in an ecological home, linen is also worth mentioning. This natural fibre has a better resistance. Moreover, it is very light. Flax felt is very economical. It is offered at a lower cost while its performance is on the same level as that of other materials. Flax is also known for its sound quality. Moreover, flax is ideal to fight against mould. Also noting its better performance in terms of thermal conductivity coefficient. Recyclable, flax is also an ecological material that promotes respect for the environment. This fibre is offered either in rolls, semi-rigid sheets, felts or strips.
