The changes in the parameters of thermal insulation plate materials based on a matrix of thermosetting phenol-formaldehyde binder and filler from cellulose-containing waste from the processing of wood, flax and cotton under the conditions of full-scale bench tests for 12 months were studied. The results of determining the strength of materials under static bending, thickness swelling after 24 hours in water, and the coefficient of thermal conductivity are presented. Samples of the material were tested after 3, 6, 9 and 12 months of stay in atmospheric conditions. The composite has a high stability of physical and mechanical parameters under prolonged impact of variable values of temperature and humidity. The thermal insulation composite obtained by the authors from cellulose-containing waste on a phenol-formaldehyde binder after a year of testing in atmospheric conditions has a residual strength of 0.87–0.9. The thermal conductivity coefficient of the material varies in the range of 0.001–0.003 W/m.K. The spread of the obtained values of the thermal conductivity coefficient of the material is comparable to the random scattering of this parameter in the experiment, due to the influence of the error of the device and the influence of random factors. The paper solves the problem of creating a thermal insulation material from unused lignocellulose waste that has a long-term resistance to variable temperature and humidity influences.
