Choose a natural insulator from an eco-industry

Given its many advantages (performance, naturalness, and complete ecological chain), range Biofib insulation is a competitive, innovative, efficient and sustainable insulation solution.

Beyond of energy saving concerns and questions of comfort, isolate its housing must be now an ecological reflex. Indeed, the protection of the planet rests on two major issues: the fight against global warming but also reduced consumption of "fossil" resources (oil, gas, ores, …).

Improve the performance of the insulation of homes, both new and renovation, is a major challenge, which our range Biofib' provides concrete answers.


A whole industry is unique in Europe

By controlling the entire industry (hemp, grinding, coating, packaging and delivery on site) Biofib 'claims singularity by combining technical performance and exemplary ecological.

The complementary strengths of hemp

Hemp is one of the insulators with the lowest CO2 impact on the environment. Compared to synthetic materials,
insulation plants are "bio-based".

No dust laying

With their long fibers, insulation plant Biofib 'do not generate dust and do not cause irritation when their implementation (unlike wood fiber for example).

The "spring" effect: an exclusive Cavac Biomaterials

Insulation panels Biofib 'have a high mechanical strength which contributes to their ease of installation and maintains lasting efficiency ensuring perfect contact between the uprights, without thermal bridges.

Actor green growth

3 storage buildings Biofib industrial site in Vendée are equipped with photovoltaic panels, 6 000m ² of roof valued for producing solar energy.

Tip: opt for an interior 100% natural lime / hemp

Coatings based on lime and hemp (boon) are especially recommended interior finish, not only for their aesthetic value, but also for their ability to promote the regulation of indoor humidity.

λ - Thermal conductivity (W / mK)

Heat flow through 1 m thick of material to a temperature difference of 1 ° C between the two faces. More ? is, the more the material is insulating.

Airtightness and performance

The thermal and acoustic performance of buildings are closely related to the sealing of insulated walls, to which the vapor barrier Biofib 'Control participates, while allowing materials to breathe naturally.

R - Thermal Resistance (m2.K / W)

Ability of a material to brake the passage of the energy. It is proportional to the thickness (e) and the thermal conductivity (?) such that: R = e / ?. More R, the higher the material is insulating.

Tip: installation of vapor barrier

If the second insulation thickness does not exceed one third of the total thickness (eg 140 + 60 -> second thickness = 30%), while the vapor barrier can be placed between two layers of insulation.

U - Heat transfer coefficient (W/m2K)

Ease with which heat energy passes through the wall. It is calculated by adding the inverse of the thermal resistance of the materials constituting the wall and surface resistances. More U, the lower wall is insulating.

Ecological solution for the equalization of land

Biofib 'screed is especially recommended for dry screeds renovation for the equalization of land in poor condition or irregular.
