Visqueen Ultimate Gas Barrier NF-600 - Gas, VOC, Radon and Damp Proof Membrane
Verified by manufacturer 29 days ago
Multi-layer thermoplastic volatile organic compound (VOC) and gas barrier.
Application
Used 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.
For site or zone characteristic gas situations of CS4 and above, contact Visqueen Technical Services.
The barrier is not intended for use where there is a risk of hydrostatic pressure.
Description
A co-extruded, multi-layer thermoplastic volatile organic compound (VOC) and gas barrier, 0.6 mm thick (600 micron). The membrane is transparent with a blue tint and supplied 2 x 50 m in a single wound roll.
Features and benefits:
- Agrément certified - third party accreditation.
- Complies with CIRIA C748:2014 - industry standard for volatile organic compounds (VOC) protection.
- Also provides radon and damp proof membrane protection.
- Dual jointing methods - depending upon specification, lap joints can be taped or heat welded.
Approvals and standards:
- Third party accreditation (BDA Agrément Certificate BAB-24-339-P-A-UK).
- Complies with the methane gas transmission rate, mass per unit area and thickness requirements of BS 8485:2015 + A1:2019.
- Suitable for all Characteristic Gas Situation (CS) ground gas regimes.
- Complies with NHBC Foundation NF94 guidance for use in Type A and Type B membrane locations (non foil system).
- Conforms to the specification requirements of NHBC Amber 1 and Amber 2 applications.
- Conforms to the specification requirements of BR 211:2023.
- UKCA UKNI CE to EN 13967:2012.
