Description
Novia A1F Grade Enhanced Polybit Building Paper is a traditional reinforced kraft paper laminate designed to meet the highest grade requirements of BS 1521 materials. Commonly referred to as Polybit, this A1F Standard Building Paper is enhanced with a clear polythene coating, providing added strength and durability, making it suitable for demanding construction conditions.
As BS 1521 does not specify strict usage guidelines, Polybit serves as a versatile and multipurpose material, adaptable to various end-user applications. It is widely used as a vapour check, an underlay for uninsulated cladding, a separation layer, and a bond break. It is also commonly applied in damp-proofing timber floors, acting as an underlay for flat lead sheets, and offering heavy-duty temporary protection. Additionally, it functions as an effective barrier against draughts and dampness in construction projects.
