So, what moments are important in high -quality insulation? Firstly, the insulation should be dry, otherwise it ceases to perform its functions. However, when the temperature decreases, moisture condensation occurs. To prevent this from happening, it is necessary to create a vapor barrier, for which vapor barrier materials will be needed. These materials that have the shape of rolls are able to maintain thermal insulation properties of the insulation for a long time. They are mounted either horizontally or vertically from the inside of the wall, located close to thermal insulation. For the seams to be sealed, use buttonage jacket tapes. To date, this method of insulation of a frame wooden house is the most effective.
