Description

A standard BS 1521 building paper with aluminium foil laminated to one face.

Vapour Control Layers (VCLs) are used to manage the transition through the building envelope of naturally occurring moisture vapour, which is produced by general building use. Our range of VCL membranes is formulated with a wide variety of construction designs in mind, delivering specific solutions for various applications and requirements.

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 compatible butyl and foil 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.

Installation guide
VCLs should always be installed on the warm side (i.e. the inside) within all wall, roof or floor insulated frame applications, and would normally be used in conjunction with Novia external breather membranes which are situated on the cold side (i.e. the outside).

Novia membranes will only perform their job if they are correctly installed using Novia tapes as part of a system. Novia uses a two-tape sealing system on all of our VCL products. It is essential that Novia membranes are installed correctly using our tapes, otherwise these products will not provide the necessary building design outcomes. One of the major causes of condensation problems within finished buildings is due to poorly installed membranes and where incorrect tapes have been used.

All Novia VCL products should be 100% fully sealed to the structure using one of our double-sided butyl tapes, and one of the foil or BOPP lap tapes to professionally complete the installation. The wider the tape used, then the stronger the final seal will be, and the easier it will be to install as there is more margin for error, so choose a tape based on your own particular application and budget. Novia recommends our 30mm wide butyl tape and our 60mm Metallised BOPP tape for all standard VCL installations.

Questions & Answers

Question:

What is the best VCL to use for a domestic application?

Answer:

There are many factors that effect the choice of VCL, Novia VC2, Novia 500 and Novia 1000 are all possible solutions but check with us or your architect for full guidance.

Question:

Do I need tapes with a VCL?

Answer:

Tapes are an essential part of ensuring a VCL is air and moisture tight. Without sealing tapes a VCL would leak and be ineffective.

Question:

Do Novia VCLs have certification?

Answer:

Yes, all Novia VCLs are manufactured to strict BS EN 13984 requirements, which is vital when looking at polythene based VCLs.
