Visqueen Gas Barrier features

The Visqueen Gas Barrier has many features over other gas barriers on the market including:
  • Flexible material
  • This is a multi-purpose gas barrier - It also serves as a radon and damp-proof barrier. Visqueen radon membrane is the perfect solution for all your gas barrier needs.
  • Lap joints can be heat-welded or taped.
  • Single Wound Rolls: The gas barrier membrane is supplied in single wound rolls, which means that it is not folded. This format simplifies the handling and installation process, as the membrane can be unrolled and laid out more easily.
  • Polyethylene Material: Visqueen Gas Barrier DPM is primarily made from polyethylene, a durable and flexible plastic material. Polyethylene is known for its resistance to moisture and chemicals, making it suitable for applications where protection against gases is essential.
  • Multiple Reinforced Layers: To increase the strength and durability of the gas barrier, the polyethylene material is reinforced with multiple layers. These reinforced layers provide added structural integrity, ensuring that the gas barrier performs effectively over time.
  • Dual jointing methods - lap joints can be taped or heat welded
  • Complies with NHBC Foundation’s NF94 guidance for use in Type A membrane locations
  • Complies with the methane gas transmission rate, mass per unit area and thickness requirements of BS 8485:2015 + A1:2019 - industry standard for methane and carbon dioxide protection

All large item orders with a value of £200.00 inc vat will be carriage paid.

*small or large classification of items are determined by weight and dimension of product*

Please note that your order may need to be split into separate packages if over 30KG.

All of the above is based on UK Mainland deliveries, further charges may be incurred if the delivery address is outside of this.

We are also currently unable to deliver outside of the UK on our regular carrier so if you require delivery outside the UK please call or email the details to the office as we reserve the right to refuse service or refund orders based on this.

Guarantee next day delivery.

Some of our products have a note that states – if ordered before 1pm and being delivered to UK mainland on a next day basis.

Please note that given the current circumstances alot of carrier companies are struggling to keep up with demand and although we do book these deliveries as next day services, the carriers cannot always fulfil these and an extra day may be required.

A high percentage of our advertised goods are stock items but be aware that if you are taking very large quantities of stock that we may not be able to fill your order fully on first delivery. Please call the office to check to not be disappointed.

We are also an active trade counter and part of a larger network of companies so stock can be taken at any time but we will always aim to deliver your goods as soon as possible.

Also if ordered along side goods that we cannot guarantee next day delivery on, these will be delivered based on the schedule of the other item.

Signature required on delivery.

The carrier we currently use requires a signature for all deliveries as a proof of delivery. If you cannot guarantee someone will be home to receive this please leave delivery instructions for a safe place or neighbour to leave your goods with. Due to covid and new contactless deliveries, our carriers will not require a signature but will take down the recipients name as POD.

If no one is available to take the delivery, the courier will leave details at the address to rearrange delivery or may leave with a neighbour. Note we may need to make an additional handling charge for the return and re-delivery if a package is unable to be delivered multiple times due to no one being home to receive this. Due to covid our carriers are restricting the number of re-delivery attempts.

After three attempted deliveries our carrier will return the goods to ourselves and in this worst case situation, we may cancel the order and refund your money, excluding any additional charge for the return and re-deliveries.

Materials delivered from our own stock.

Normally 1 – 2 days (this can sometimes be longer if we are waiting for manufacturers’ stock to arrive into ours).

If the order is placed before 1:00pm and all of the items are in stock, then we will endeavour to dispatch your order same day for delivery the following day.

This still applies for deliveries out of our local area but please note that we use independent carriers so be aware that there may be external factors which we cannot control (e.g Far out postcodes or local traffic situations)

Materials delivered direct from the manufacturer.

There may be some occasions when it is more efficient or cost effective to have the materials shipped direct from our suppliers to the customer.

We will place the order immediately upon receipt of your order but this can sometimes take a few working days depending on the manufacturers production schedule or carrier used.

We will always endeavour to get the goods to the customer at the earliest possible date but if these are urgently required, please speak to us to check.

Please note that many manufacturers will offer a next day delivery service at an increased delivery cost and also a cut of time for this order to be placed (usually around 11am / 12pm)

Please call us on 08454 530 017 between 8am and 5pm Monday – Friday or email us on [email protected] for any delivery queries, or urgent requirements.

Please read our full terms and conditions with regard to full details on deliveries.

Visqueen Gas Barrier is a multi-layer reinforced polyethlene gas barrier membrane with a 20 micron aluminium foil. It's used to prevent the ingress of harmful levels of ground gases such as methane, carbon dioxide and radon.

To install Visqueen Gas Barrier, lay loose on the substrate with the blue side up to avoid sunlight glare.

Make sure the barrier is clean and dry at the time of jointing, then overlap by at least 150mm, bond with Visqueen Pro Double Sided Jointing Tape and seal with Visqueen Gas Resistant Foil Lap Tape. Alternatively, you can heat weld the lap joints for an effective seal, in which case the lap joints can be less than 150mm provided the joint integrity is not compromised. 

Finally, all service entry points should be airtightly sealed using Visqueen Preformed Top Hat Units. For the base of the top hat and the upstand, bond using Visqueen Pro Double Sided Jointing Tape and seal with Visqueen Gas Resistant Foil Lap Tape.

Visqueen Gas Barrier is made of reinforced polyethylene, with a 20 micron aluminium foil.

Visqueen Gas Barrier can provide protection against gases such as methane, carbon dioxide and radon.
