We are pleased to announce that they have received their renewed BBA Certification for the Visqueen Gas Barriers.
Visqueen Building Products Gas Barrier has achieved re certification due to it being retested in line with the new requirements to BS8485:2015. The Visqueen Gas Barriers meet the standards outlined in the BS8485:2015 document and has also passed BS ISO 15105-1, which is the methane permeability testing that these products must pass.
The Certificate relates to Visqueen Gas Barrier, a gas barrier and damp-proof membrane, for use in concrete ground floors above and below slabs not subject to hydrostatic pressure, to protect the building against moisture, radon, methane and carbon dioxide from the ground.
The key factors of the Gas Barriers which were assessed are, the resistance to water vapour, resistance to underground gases, resistance to puncture and the overall durability of the Gas Barrier. Continue reading →
Building Regulations require proper precautions be taken to prevent danger to health and safety when building on contaminated land. Visqueen Gas Barrieroffers a safe solution for the protection of buildings against Methane, Radon, Stythe (a gas commonly found from disused mines, also known as blackdamp) and Carbon Dioxide; when installed in accordance with the relevant codes of practice such as BRE, CIRIA and the Chartered Institute of Environmental Health Ground Gas Handbook.
Visqueen Gas Barrier is a multi-layer reinforced polyethylene membrane with an integral aluminium foil that is approved for use in NHBC Amber 2 applications.
For ease of identification on site, Visqueen Gas Barrier is coloured blue on one side and silver on the other.
The barrier combines strength and performance with flexibility and easy installation. Visqueen Gas Barrier also acts as a damp proof membrane.
In this video, we demonstrate how to create a joint using Visqueen Gas Barrier and a pre-formed 90 degree corner unit.
The tools required for this are, a roller with a neoprene wheel and a sharp knife or pair of scissors. To complete the job you will need Visqueen Gas Barrier, Visqueen double sided jointing tape, Visqueen Gas Barrier foil jointing tape (which is single sided) and the pre-formed 90 degree corner unit, which is reversible.

Visqueen Gas Barrier
Visqueen Gas Barrier is a multi-layer reinforced polyethylene membrane with an integral aluminium foil. For ease of identification on site Visqueen Gas Barrier is coloured blue on one side and silver on the reverse. The barrier combines strength and performance with flexibility and easy installation.
Low permeability to methane, radon and carbon dioxide.
High quality multi-layer reinforced LDPE membranes with aluminium core with high levels of tear and impact resistance.
High resistance to puncture.
Complies with relevant codes of practice such as BRE and CIRIA.
Visqueen Gas Barrier and ancillary components must be installed in accordance with the recommendations of Building Research Establishment BRE 414 “Protective measures for housing on gas contaminated land” and CIRIA C665 “Assessing risks posed by hazardous ground gases to buildings”, NHB C guidelines, and the Chartered Institute of Environmental Health Ground Gas Handbook. The product is not intended for use where there is a risk of hydrostatic pressure. Continue reading →
