Polybit Building Paper 1m x 25m (25m2 Roll)

This is a traditional, polythene coated, reinforced kraft paper bitumen-bonded, building paper laminate. Manufactured with wet-strength kraft paper and meeting the technical requirements of BS 1521, Class A1F, for water-proof building papers, the product utilises polymer reinforcing scrim.

Novia Polybit is a clear polythene coated version our A1F Standard Building Paper, typically used where conditions require additional strength and durability. 

Unlike many other recent developments in building membranes (eg breathable roof underlays), BS 1521 does not give guidance on suitable use, and as such this product is a generic material, serving a wide range of end-user defined applications. 

However, typical usage for Polybit has naturally evolved over time including for example, vapour checks, underlay on uninsulated cladding, flat lead-sheet underlay, timber floor DPM and heavy-duty temporary protection.
