Kosteussulkuihin
Kosteussulkuihin, also known as vapor barriers or vapor retarders, are materials used in building construction to impede the passage of moisture vapor. Their primary function is to prevent moisture from migrating through building assemblies, such as walls and roofs, where it could condense and cause damage. This condensation can lead to issues like mold growth, rot, and reduced insulation effectiveness.
The placement of a kosteussulkuihin is crucial and depends on the climate. In colder climates, it is
Common materials used as kosteussulkuihin include polyethylene sheeting, kraft paper facings on insulation, and certain types
