FR Reflective Vapour Control Layer is a traditional specification, single-ply, non-laminated, virgin-grade blown polythene material. It is designed for use as an air leakage barrier and vapour control layer (AVCL) in insulated wall, roof and floor applications. The FR Reflective Vapour Control Layer must be installed in conjunction with a two-tape sealing system to provide a fully airtight seal.
Recommended for use with Cold Weather Foil Tape.
This product has a reflectivity in excess of 95%, which will significantly improve both U and R values when correctly installed. FR Reflective Vapour Control Layer will also deliver a very low moisture vapour permeability solution due to the use of high performance materials. To provide an air tight seal FR Reflective Vapour Control Layer must be installed in conjunction with suitable tapes.
