Description
Novia Black+ Roof and Wall Breather Membrane is a high-quality, multi-purpose membrane designed for use in both cold and warm pitched roofs, as well as insulated wall applications. It provides excellent water resistance while maintaining high breathability, ensuring the structure remains well-ventilated and protected from moisture damage.
This membrane features a matt finish slip-resistant surface, offering a lightweight yet strong composition with exceptional tensile and nail tear strength. It is rigorously tested to meet EN 13859-1 and EN 13859-2 standards for pitched roofing and walls, making it a reliable choice for modern construction projects.
Features and Benefits
- Suitable for use in all pitched cold and warm roofs, as well as high-specification wall applications
- Highly vapour permeable while providing excellent water resistance
- Can be installed directly over insulation, boarded roofs, or rafters
- Matt finish slip-resistant surface for improved handling and safety
- Strong tensile and nail tear strength for durability
- Compliant with BS 5534 wind uplift requirements in zones 1 to 5 when used with tape
Installation Guidance
To ensure airtightness and optimal performance, it is recommended to use Novia installation tapes. For basic installations, Novia Breather Membrane Lap Tape is suitable, while Novia Double-Sided Adhesive Tape is ideal for high-specification projects. Using both tapes results in a long-lasting, breathable, and airtight seal, even where tape use is not mandatory under BS 5534 wind uplift test results.
For wall or warm roof applications, installing a Novia vapour barrier such as Novia VC2 or VC200 Reflective on the warm side of the insulation is essential to prevent interstitial condensation. Even minor moisture contamination within the insulation can reduce thermal performance by over 30%.
Standards and Certification
- British Standard: BS 5534
- Fire resistance rating: classified as Grade E under EN 13501-1
- UKCA certified to EN 13859-1 (roof) and EN 13859-2 (walls)
Additional Information
- Novia Black+ is black on one side and grey on the other, with no text or images except for overlap guidelines
- While this breather membrane helps minimise condensation risk within the roof space, condensation cannot always be completely eliminated under specific atmospheric conditions
- Ensure sufficient ventilation is incorporated to comply with all relevant building regulations and technical standards, such as BS 5250
Novia Black+ is a versatile and durable solution for roofing and wall applications, providing long-term moisture control and breathability in modern construction projects.

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!!
