The final report contains the results of studies of changes in the microwave signal attenuation for various wooden building materials, depending on the degree of humidity of the samples and the direction of propagation of the electromagnetic wave. The new method of non-destructive quality control of glass windows constructions is substantiated, which, unlike the existing ones, takes into account the voltage of the spark arrester breakdown as the information coordinate.
