Fuktmembran

Fuktmembran, often translated as moisture barrier or damp-proof membrane, is a material or layer applied to construction elements to prevent the passage of moisture. Its primary function is to protect buildings and their components from water damage, which can lead to structural degradation, mold growth, and reduced insulation effectiveness.

These membranes are commonly used in various building applications. In foundations and basements, fuktmembran is installed to prevent ground moisture from rising into the building structure. This is crucial for maintaining a dry and healthy living environment. In roofs and walls, they serve to block external water ingress, such as rain and snowmelt, while often allowing water vapor to escape from within the building, a process known as breathability.

The materials used for fuktmembran vary widely. Common types include bitumen-based sheets, plastic films (like polyethylene), and specialized liquid-applied coatings. The choice of material depends on the specific application, expected exposure to moisture, and building codes. Proper installation is paramount to the effectiveness of a fuktmembran, ensuring continuity and sealing all joints and penetrations to create an unbroken barrier. By controlling moisture, fuktmembran contributes significantly to the longevity and performance of a building.
