Visqueen Radon Membrane is manufactured from an enhanced blend of polymer films that is suitable for use in the protection of buildings from the ingress of radon gas.

Visqueen Radon Membrane also acts as a damp proof membrane, but is not intended for use where there is the risk of hydrostatic pressure. It is approved for use in Ireland and installed in accordance with BRE Certificate No. 083/01. Visqueen Radon Membrane and ancillary components must be used in accordance with the recommendations in the most recent edition of Building Research Establishment Report BR 211.

It can be used in most common floor constructions and is installed in a similar way to a damp proof membrane, but with much greater attention paid to workmanship and detailing in order to achieve effective sealing at all locations.

For installation and test results information please refer to the manufacturer's datasheet.

Visqueen's products are manufactured under a Quality Management System approved to ISO 9001: 2008; Environmental System 14001:2004 and BS OHSAS 18001:2007.
