Novia Black+ Supreme is a high-quality, strong and versatile 125gsm breathable membrane designed for pitched cold and warm roofs and insulated wall applications. Its 3-layer construction incorporates a microporous core, combining Class W1 water resistance with high vapour permeability, airtight performance and good tensile and nail tear strength.
Novia Black+ Supreme meets EN 13859-1 for pitched roofing and EN 13859-2 for walls, achieves Class W1 water resistance to EN 1928 and complies with Class E Fire Classification.
With an Sd value of just 0.029m, the membrane provides high vapour permeability for effective moisture management within appropriately designed insulated roof and wall constructions.
Supplied as a 1.5m x 50m roll, each roll provides 75m² nominal coverage and weighs approximately 9.5kg.
Key benefits include:
Novia Black+ Supreme is designed as a breathable membrane for both pitched roofing and insulated wall applications.
Typical uses include:
Its combination of roof and wall compatibility allows the same high-quality membrane to be used across different elements of a building project.
Novia Black+ Supreme has a nominal membrane weight of:
125gsm to EN 1849-2
The membrane uses a 3-layer construction with a microporous core, providing a balance of strength, water resistance and vapour permeability.
The 125gsm construction provides a substantial membrane for roof and wall applications while remaining practical to handle during installation.
Novia Black+ Supreme achieves:
Class W1 resistance to water penetration to EN 1928
The membrane also retains:
Class W1 water resistance after ageing
This provides tested resistance to water penetration while maintaining the vapour-permeable characteristics required from a roof and wall breather membrane.
Novia Black+ Supreme provides an:
Sd value of 0.029m to EN ISO 12572
This low Sd value indicates high vapour permeability, allowing water vapour to diffuse through the membrane as part of an appropriately designed roof or wall construction.
This supports moisture management within insulated building elements.
Novia Black+ Supreme is specified as both airtight and vapour permeable.
These characteristics describe two different aspects of membrane performance.
Airtightness helps restrict uncontrolled bulk air movement through the membrane, while vapour permeability allows water vapour to diffuse through the material.
Correct installation and appropriate sealing are important to achieving the intended performance across the complete construction.
Novia Black+ Supreme meets EN 13859-1 for pitched roofing and is suitable for both:
Its combination of W1 water resistance, high vapour permeability and good mechanical strength provides a versatile membrane for a wide range of pitched roof applications.
The membrane also meets EN 13859-2 for walls, making it suitable for insulated wall construction.
Typical applications can include:
Its low Sd value supports the passage of water vapour through the membrane while its W1 classification provides resistance to water penetration.
Novia Black+ Supreme provides tested tensile strength of:
Machine Direction (MD): 285 N/50mm
Cross Direction (CD): 165 N/50mm
These values are tested according to EN 12311-1 and demonstrate the membrane’s strength in both directions.
The membrane provides tear resistance of:
Machine Direction (MD): 125 N
Cross Direction (CD): 120 N
These values are tested according to EN 12310-1.
Good tear resistance helps provide a robust membrane during handling, positioning and fixing.
Novia Black+ Supreme has tested elongation values of:
Machine Direction (MD): 70%
Cross Direction (CD): 90%
These figures are measured according to EN 12311-1.
Novia Black+ Supreme has a stated low-temperature stability of:
No cracking at -60°C to EN 1109
This demonstrates the membrane’s ability to retain its integrity under the specified low-temperature test conditions.
Novia Black+ Supreme has been tested for BS 5534 wind uplift requirements.
Roof membrane wind uplift requirements can vary according to factors including:
The relevant Novia technical guidance should be consulted to determine the appropriate fixing and sealing requirements for the individual project.
Novia Black+ Supreme should be installed according to BS 5534 UV guidance.
The membrane should not be assumed suitable for indefinite exposure to ultraviolet light.
Exposure during installation should be controlled according to the relevant technical guidance and project requirements.
Novia Black+ Supreme complies with Class E Fire Classification.
The membrane should be specified as part of the complete roof or wall construction according to the fire performance requirements of the individual project.
Novia Black+ Supreme is specified as:
This allows the membrane to provide a single solution across appropriate pitched roof and insulated wall applications.
Novia Black+ Supreme is:
Black on one side and grey on the reverse
The membrane has no printed text or imagery apart from an integrated 150mm overlap line.
The incorporated 150mm overlap line provides a convenient reference when positioning adjoining membrane sheets during installation.
The actual overlap and sealing requirements should follow the relevant Novia technical guidance and requirements of the individual roof or wall construction.
Each roll measures:
1.5m wide x 50m long
Providing:
75m² nominal coverage
Each roll weighs approximately:
9.5kg
Actual usable coverage will be lower once required overlaps, cutting, penetrations, detailing and general installation wastage are taken into account.

Yes. Novia Black+ Supreme incorporates a 150mm overlap line to assist installation.
Both versions use the same 125gsm Black+ Supreme roof and wall breather membrane.
The difference is the roll width and nominal coverage:
The 1.5m version therefore provides 50% more nominal membrane area per roll.
Both are strong 3-layer roof and wall breather membranes with microporous cores, W1 water resistance and vapour-permeable performance.
The principal difference from the supplied specifications is membrane weight:
Black+ Pro is the heavier membrane, while Black+ Supreme provides a strong 125gsm option with detailed tensile, tear and vapour performance data.
Yes. The 75m² figure represents the nominal area of the complete roll.
Allowance should be made for membrane overlaps, cutting, penetrations, detailing and general installation wastage when calculating the number of rolls required.
