The article presents the results of measurements of thermal conductivity coefficients and thermal resistances of non-autoclaved foam concretes based on microsilica depending on their average density. It is experimentally established that reducing the grade of non-autoclaved foam concrete from D800 to D400 by increasing the porosity of samples leads to a decrease in the thermal conductivity coefficient by 2.4 times and an increase in the thermal resistance of the layer by 2.5 times.
