Abstract
The results of research on the production of structure-forming material for thermal insulation from birch bark are considered. After studying the properties of the bark, it was proposed to divide birch bark into bast and birch bark. The influence of fractionated compositions of bark, bast and birch bark on the thermal conductivity coefficient of experimental compositions was studied. It has been established that birch bark has the greatest heat-insulating effect. Regardless of the method of grinding birch bark at a density of 100–150 kg/m3, the thermal conductivity coefficient is 0,037–0,039 W/(m∙°C).
