Visqueen Ultimate Gas Barrier NF-500

Visqueen Ultimate Gas Barrier NF-500 is a co-extruded, multi-layer thermoplastic volatile organic compound barrier and gas barrier, 0.5mm thick (500 micron). The membrane is transparent with a green tint and supplied 2.4m x 43.5m in a single wound roll.

Visqueen Ultimate Gas Barrier NF-500 is suitable for use in all types of buildings to prevent the ingress of harmful levels of volatile organic compounds (VOCs), methane, carbon dioxide and radon.

The barrier can be positioned above or below reinforced cast in situ concrete floor slabs e.g. ground bearing, suspended or raft, or above precast suspended segmental subfloors, e.g. beam and block floor.

The barrier can also be used as a high performance radon membrane and/or damp proof membrane. Where protection against VOCs or hydrocarbon contamination is required, the barrier system should be applied with welded joints.
