Home > Natural insulation
Beyond concerns for energy savings and comfort issues, 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, ... ).
Hemp, pulping and topping, packaging and delivery on site : controlling the entire industry, Cavac Biomatériaux boasts its uniqueness by combining technical performance and exemplary ecologically :
Improve the performance of the insulation of homes, both new and renovation, is a major challenge, which our range Biofib ' : effective insulation and really durable!
"Hemp comes from our fields, located within 100km of the industrial site, Vendée ( 85). By choosing insulation Biofib', you support local employment and the values of a 100% french production."
Director Cavac Biomatériaux
For a healthy home in which to live, insulation Biofib' provide a unique atmosphere of comfort : hemp naturally manages humidity, which ensures you a feeling of well being throughout the year (summer comfort).
Consumers are increasingly sensitive to environmental issues and "natural" products.
Hemp is a culture respectful of the environment :
Energy savings for heating always rhyme with "savings" simply. To further encourage citizens to make the right choices for the planet, many incentives have been implemented in the framework of the Grenelle Environment (french government support). The effects of the economic crisis had the effect of reducing the level of state aid in the support and development of "green" industries (lower thresholds of tax credits). However, the latest Finance Act 2010 preserved the principles of this tax "green". A brief overview of various measures to improve energy efficiency (and / or promoting renewables) :
This progressive approach must be collective. The new standards aim to build a significant reduction in energy expenditure : RT2012, BBC...
1 - The hemp straw fix CO2 (via photosynthesis ) during growth, thus contributing to a very low carbon footprint.
2 - Plant fibers used are from hemp produced in Vendée near the industrial site ( within 100 Kms) where low CO ² emissions for transport to the factory.
3 - 2 steps "pulping" and "topping" are performed on a single site : a first in Europe.
4 - After pulping, the fibers are processed into insulating panels but no waste because all coproducts ( chènevotte, dust) are valued in other markets ( coated building, bedding, ...).
5 - The industrial process of topping is fully automated, with a systematic quality of finished products (weight, thickness and density) which guarantees quality and performance (technical CSTB, ACERMI certificate No. 11/130/696 ) control for insulating Biofib.
6 - Delivery is via an optimized logistics system also reduces transport costs and associated pollution.
7 - Given its thermal performance, implementation insulation Biofib ' contributes to an excellent home insulation, source energy savings.
Exclusive Cavac Biomatériaux, actor green growth, harvest the plant delivery.
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.
