Wall insulation with sawdust concrete is carried out using a heat-insulating type of material. Its density is no more than 400 kg / m3, but its thermal conductivity does not exceed 0.11 W * ms. That is why the insulation with sawdust concrete is even more popular than the construction of walls using it. And not only products are used.
