High spec solution for gas contaminated sites

Kent based membrane specialist Novia Ltd has developed a new methane barrier membrane solution for use on gas contaminated sites. It complements their current extensive membrane range which includes AVCL’s, vapour permeable membranes and speciality laminates. Novia says it is also the UK market leader in BS 1521 building papers.

Novia Methane Pro is a high specification multi-layer virgin grade LDPE laminate incorporating scrim reinforcement and an aluminium foil core, and is designed for use as a loose-laid methane and CO₂ barrier.

Novia Methane Pro has passed the stringent sheet and joint tests to BS ISO 15105-1, and is fully BS 8485:2015 compliant. The membrane also acts as a radon gas barrier and general purpose damp proof membrane, and is therefore also CE approved to BS EN 13967.

The product comes in a handy size 80m², 1.6m x 50m roll, and is installed using the Novia 2-tape sealing system.

By using carefully chosen manufacturing materials and production processes Novia has produced a low cost and high specification BS 8485:2015 compliant methane barrier that is easy to install, and readily available off the shelf. Architects and designers can easily specify Novia Methane Pro via RIBA NBS Plus software.

Adrian Chisholm, Managing Director of Novia Ltd, said: “With on-going issues finding suitable building land in the UK, there is a growing need for gas protection measures that provide solutions for contaminated sites. The introduction of the new BS 8485 standard in 2015 has driven forward product development, but there have been some difficulties within the industry in meeting the new membrane testing standards. Novia is therefore very pleased to be able to provide a fully tested and compliant methane barrier solution”
