During the construction of the house, special attention should be paid to the conduct of high -quality thermal insulation of the dwelling. This is especially true for a competent choice of high -quality insulation. Below we will consider which market options are available today and which of them are most effective. For example, take expanded clay and minvat to buy or not choose you. First of all, you need to decide on the issue for what purposes the material is needed: insulation of walls, roof, ceilings or attic. After all, each of the heat insulator under consideration has individual advantages and disadvantages. And in this case, thermal conductivity will be taken as the first defining criterion. In expanded clay, this coefficient is 0.1, and in mineral wool - 0.04.
