Novia A1F Building Paper

A traditional building paper, meeting technical requirement of BS 1521 for waterproof building papers.

Product Overview

Novia® A1F Building Paper is a traditional reinforced kraft paper which has been laminated together using bitumen. Manufactured using wet-strength kraft paper and meeting the technical requirements of BS 1521 for waterproof building papers, Novia® A1F has a polymer reinforcement scrim running throughout the bitumen core of the material. 

Novia® A1F meets the highest specification of BS 1521, class A1F, making it suitable for a wide range of user defined projects within the construction industry.

Unlike many other recent developments in building membranes (eg breathable membranes and Air & Vapour Control Layers), BS 1521 does not give guidance on suitable use. As such Novia® A1F is a generic material, serving a wide range of end-user defined applications. 

However, typical usage for Novia® A1F has naturally evolved over time and some of the typical uses which has made A1F such a popular product for several decades include:

• Vapour check & air movement barrier

• Underlays on uninsulated cladding

• Temporary protection

• Separation layer

• Bond breaks

• Draught and damp exclusion

Novia is the market leader for BS 1521 building papers, so we can offer our expert guidance where required.

Novia® A1F can be found on NBS Chorus and NBS Source software packages. Full information can be found for NBS specification with the table below. The links will open a pop up window with full specification information.
