Kosteussulkukerros
Kosteussulkukerros, often translated as a moisture barrier or vapor retarder, is a critical component in building construction designed to prevent the uncontrolled passage of water vapor through building assemblies. Its primary function is to regulate humidity levels within walls, roofs, and floors, thereby protecting the structure from moisture-related damage such as rot, mold growth, and reduced insulation effectiveness.
The effectiveness of a kosteussulkukerros is measured by its permeance, which indicates how easily water vapor
Proper installation is paramount to ensure the kosteussulkukerros performs its intended function. Gaps, tears, or improper
