Novia Class B-s1,d0 VC4000 FR Reflective AVCL

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 BS EN 13984 and is UKCA approved. Novia® VC4000 FR complies to EN 13501-1 Fire Classification Class B-s1, d0* and is approved 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 and r 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 also offer Novia® FR Breather. It has a B-s1,d0 Fire Classification and is approved for use in high rise applications. See datasheet 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.
