The invention relates to thermal insulation materials made of lignocellulose biomass and binder with the following ratios of the components: lignocellulose biomass 25–71.4 % by weight, xanthan gum 0.6–3 % by weight, water 26.8–71.25 % by weight, glycerol 1.2–4.5 % by weight and ethanol 0–2.8 % by weight. It is a natural material that is not harmful to human health and the environment. It has competitive thermal conductivity properties (thermal conductivity coefficient 0.045–0.060 W/(m*K)) and good moisture transfer properties (water vapour resistance coefficient 2.09; moisture buffer capacity 4.7–6.11 g/(m2*% RH)). Its manufacturing technology can be used for the production of non-standard forms of thermal insulation materials, thus diversifying its applicability.
