Novia B1F Building Paper 1.25m x 50m 62.5m2

Building Papers are typically kraft paper-based materials reinforced with polythene, foil, scrim, etc, to help control the transfer of moisture and vapour between the interior and exterior of a building.

Building papers are typically used in Cladding and Underlay in uninsulated buildings (for example, a shed), flat lead roofing underlay, or temporary protection during projects. However, they are versatile products that can be used for a multitude of purposes. Typically Building Papers - other than AF1 building paper - are not designed for permanent applications and instead are recommended for temporary applications only.

Building Papers have a variety of use cases, but typically they are used in a similar use case to breathable membranes - in that they are applied to the exterior side of a wall or roof structure to provide resistance to moisture. However, Building Papers are often not breathable and not always designed as a permanent solution.

Due to the variety of uses, there is not one standard recommended method of application, so methods for applying and using Building Papers will vary depending on your project.
