Product Overview
Novia FF1 is our foil-faced waterproof building paper meeting the requirements of BS 1521 A1F.
Novia® FF1 Building Paper meets the highest specification of the BS 1521, class A1F, making it suitable for a wide range of construction projects. Some of the typical uses which has made FF1 such a popular product for several decades include: vapour check, underlays on uninsulated cladding, temporary protection, separation layer, bond breaks, draught and damp exclusion in non residential applications, and air movement barriers. BS1521 is a technical standard, not an application or product standard, and therefore the end user is responsible for determining the suitability for any given application.
This product could be used as an air-leakage barrier, to prevent losses due to unwanted convection flows. We also advise the use of Novia butyl tapes and metallised BOPP sealing tapes to ensure complete barrier integrity throughout the entire life of the product.
Novia FF1 should be used in combination with Novia breather membranes to provide an air-tight and vapour resistant system.
Novia FF1 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.
