Traditional materials include felt, moss and pakal. Their advantage is naturalness and high environmental friendliness. However, the use of these funds requires large time resources. In addition, there is a need to conduct insulation more than once. The same characteristics have modern materials — jute and linen fiber. They have the advantages and disadvantages of traditional materials. Innovative methods of insulation — sealant and putty — allow for hemp operations much faster and are much cheaper. Due to the fact that the sealant has the ability to expand and narrow during the movement of the construction, there is no need to wait for the moment of shrinkage of the log house. In addition, manufacturers offer a wide range of color solutions, which positively affects the external attractiveness of the house. When choosing a putty or sealant for hemp, it is necessary to rely on the size of the cracks and gaps, as well as on the breed of the tree from which the log house is made.
