B1F Building Paper 1.25m x 50m (62.5m2 Roll)

Estimated Delivery Time Of 2-3 Working Days

Please note this product is non returnable

This is a 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. 

Novia B1F meets the technical requirements of BS 1521 (Class B with reinforcement) for water-proof building papers, utilising polymer reinforcing scrim to increase strength and general product performance.

Key Features:

  • Bitumen, paper and reinforcement scrim laminate
  • Lowest cost reinforced product
  • Roll sizes 1.25m x 50m
  • Multi-use adaptable building product
  • Made to BS 1521 Class B

 Note: Novia products are non returnable if over or incorrectly ordered
