Highlights of ceiling vapor barrier
When water vapor enters the premises of the house, condensation may occur, which will moisten the insulation, finishing material, as well as the wooden parts of the roof. Because of this, the insulation can lose the ability to save heat, the decoration will become unusable, and the raw tree will begin to predict. To reduce the likelihood of such negative consequences, you need to make a vapor barrier of the ceiling. As a rule, a special film is used as a material for vapor barrier, attached below the roof insulation. Polyethylene films are aging quickly enough, which is why it is advisable to use them to arrange a vapor barrier of the ceiling. For vapor barrier, you can also use permamine, aluminum foil, roofing material and only. The last three material is better not to use in baths, because they can distinguish toxic substances, but also not the most pleasant aromas during operation. The ceiling can be shut up with dense cardboard, which must be impregnated with an Olifoy in advance, and aluminum foil is also used. A layer of clay should be applied to the vapor barrier layer.
