Varieties of vapor barrier for a private cottage
Widespread due to the provision of high vapor barrier and air insulation is given to polyethylene.
But even this material is not able to create a sufficiently powerful continuous barrier to prevent vapor penetration. There are a lot of areas in the houses that cannot be covered with polyethylene, these include smoke pipes, the moves of the ventilation system, the place of passage of pipes and cables.
In such sites, specialists take a number of measures to improve the quality of the material used when creating a barrier from it that prevents the penetration of steam and air flows. Air -resistant materials should have high strength. Unlike air -resistant materials during steam isolation, materials do not experience such a voltage and easily prevent the pressure of vapor and moisture.
