The object of research is the thermal conductivity of aerogel thermal insulation under stationary thermal conditions. Method. The study uses an experimental research method. Results. The actual thermal conductivity coefficient of the innovative aerogel nanomaterial in the form of a roll insulation was determined. It is equal to 0.0227 W/(m*K). This value is within the margin of error. Among the thermal insulation materials in the construction market, the material Alison Aerogel Blanket DRT06-Z stands out with the lowest coefficient of thermal conductivity.
