Flax is a by product of agriculture is one of the main textile plants cultivated for thousands of years.
Undemanding in pesticides and fertilizers, it is now mainly produced in the north of France including Normandy for the textile industry, the short fibers are not used by the textile industry are recovered for developing felts 'insulation.
Carded and needled, thermobonded with polyesthers (maximum 15%) it is packaged in the form of panels and semi-rigid rolls thermal and acoustic insulation.
It has good hygroscopic: linen wool can absorb 10 times more water than glass wool (without damage).
The linen wool is easier to work with than hemp. It lends itself to manufacturing larger thicknesses.
- Thermal conductivity: 0,035 0,04 to W / m ° C.
- Thermal resistance for a layer cm 10: 0,1 / 0,035 2,86 = m² ° C / W..
