Novia B1F 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 requirements of BS 1521, grade B1F (Class B with reinforcement). 

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 B1F has naturally evolved over time including for example, separation layers for insulated screeds, bond breaks, temporary protection and garden buildings.

  • Bitumen, paper and reinforcement scrim laminate
  • Lowest cost reinforced product
  • Roll sizes 1.25m x 50m
  • Multi-use adaptable building product

Installation Tips

As this product has many different uses, the installation will vary depending on the final use and would be down to the installer to ensure they are happy with any given application.
