Dampskydd
Dampskydd, often translated as vapor barrier or vapor retarder, is a material or system designed to restrict the movement of moisture vapor through a building assembly. Its primary purpose is to prevent condensation within walls, roofs, and floors. When warm, moist indoor air comes into contact with a colder surface within a building's structure, water vapor can condense into liquid water. This condensation can lead to various problems, including mold growth, rot, and degradation of building materials.
The effectiveness of a dampskydd is measured by its permeance, which is the rate at which water
In cold climates, the dampskydd is typically installed on the warm side of the insulation, preventing indoor
