Description
The Novia 500 VCL is a high-quality, affordable vapour control layer designed for timber frame construction walls and other applications where managing the passage of water vapour is essential. Manufactured from virgin blown polythene, this clear, green-tinted membrane ensures effective vapour resistance while also acting as a barrier against air leakage.
This product is fully compliant with Construction Products Regulation (CPR) standards and is CE Approved to EN 13984:2013. It is an ideal solution for preventing unwanted moisture movement within the building envelope, reducing the risk of condensation and energy loss due to convection flows.
Features and Benefits
- Dimensions: 2.7m width x 50m length
- Total roll coverage: 135m²
- Roll weight: 15.5kg
- Manufactured from virgin polythene
- 500 Gauge / 125 Micron material thickness
- Clear polythene with a green tint
- Provides an effective vapour control layer
- Acts as an air leakage barrier, enhancing energy efficiency
- Compatible with Novia breather membranes for a complete system
To ensure full barrier integrity, Novia recommends using compatible sealing tapes. Novia double-sided butyl tape should be applied with an overlap of 75mm to 100mm, followed by a secure lap-seal using Novia foil tape.
The width of the tape will determine the strength of the seal, so selecting the appropriate size based on application needs is crucial. For improved airtightness, applying butyl tape to timber studs at fixing points before stapling the membrane enhances the overall seal.
Standards and Certification
- CE Approved to EN 13984:2013
- Water vapour resistance: at least 250 MNs/g to EN 1931
The Novia 500 VCL is an excellent choice for builders and contractors looking for a cost-effective and reliable vapour control solution.

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.

Right product, right price, right delivery.
Right product, right price, right delivery. Sure, it was only one length of cast iron guttering but they took the order seriously, packed it well and kept me updated on delivery. And when I opened the very good packaging I found it was exactly what I had wanted. How can you do better!!
