Novia A1F Building Paper

Our lower cost reinforced building paper

Product Overview

This is our traditional reinforced kraft paper bitumen-bonded building paper laminate used within the construction industry, which meets the highest standard of BS 1521 materials, grade A1F.

Unlike many other recent developments in building membranes (eg breathable roof underlays and air leakage barriers), 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 A1F has naturally evolved over time including for example, vapour checks, as an underlay on uninsulated cladding, flat lead-sheet underlay, timber floor DPM and temporary protection.

Novia Ltd are the market leaders for 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.
