Novia FF1 Foil Faced Building Paper
Our foil faced BS 1521 A1F building paper
Novia FF1 is our foil-faced waterproof building paper meeting the requirements of BS 1521 A1F. This is a traditional reinforced kraft paper bitumen-bonded building paper laminate used within the construction industry. It is primarily used as a vapour barrier membrane in walls and ceilings of insulated building structures, to reduce or prevent interstitial condensation.
This product performs the additional function of 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 is available 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.

To install the membranes, we recommend using the Novia double tape system.
