Novia Class B VC4000 FR Reflective AVCL

Our Fire Classification B-s1,d0*, reflective AVCL suitable for high rise applications

Product Overview

Novia® VC4000 FR Reflective is a premium quality, high performance, Class B* flame resistant, reflective Air & Vapour Control Layer (AVCL). The material meets EN 13984 and is UKCA marked. Novia® VC4000 FR complies to EN 13501-1 Fire Classification Class B-s1, d0* and is suitable for use in high rise applications. Novia® VC4000 FR has excellent moisture vapour resistance and is suitable for use in any insulated wall or roof application where high moisture vapour resistance is required. Novia® VC4000 FR also has a reflectivity of 98%, which will significantly improve both U values when correctly installed. Due to the use of high performance materials, Novia® VC4000 FR will provide a very low moisture vapour permeability solution. The product is reflective on one side, white on the reverse, with no text or images. 

*Valid for substrates with fire class A2-s1,d0 or A1 such as 12mm plasterboard, with no cavity between product and substrate. Product tested to EN 13501-1.

Novia® VC4000 FR meets the requirements for UKCA marking, originally introduced under the 2013 Construction Products Regulations with CE marking. Under this European directive, all products covered by a current hEN (harmonised European Norm) must comply with the new standard. Third party accreditation is no longer sufficient. This has been adapted to UKCA following the UK departure from the EU.

For projects that also require a fire rated breather membrane which complies to EN 13501-1, we offer several fire rated products. See datasheets for more product specific information.

Novia® VC4000 FR 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.

Full installation and technical details can be found on the datasheets available for download below.

Installation Tips

Installation guidelines can be found on the product datasheets using the links to the left. To install the membranes, we recommend using the Novia double tape system.

Our Novia® Double-Sided Butyl Tape is used on the laps and edges of the membrane, with one of our Novia® Single-Sided Lap Tapes (SSLT) used to complete the lap seal. For fire rated AVCL membranes, we offer our 96mm width, Class B-s1,d0 Novia® FR Aluminium Foil Tape. For difficult areas to seal with tapes, or for additional support in certain applications, Novia® AirSeal 310 FR is available.

Novia FR Aluminium Foil Tape acheives Fire Classifcation B-s1,d0 in accordance with EN 13501-1. Novia Double-Sided Butyl Tape is not fire rated. Tapes & sealants are excluded under relevant sections of “Fire Safety: Approved Document B”. Please see individual tape datasheets for more product specific information.
