What Is Novia Black+ Pro Used For?

Novia Black+ Pro is designed as a high-performance breather membrane for both pitched roofing and insulated wall construction.

Typical applications include:

  • Pitched cold roofs
  • Pitched warm roofs
  • Insulated walls
  • Timber frame walls
  • Framed construction
  • Residential roofing
  • Commercial roofing
  • New-build projects
  • Refurbishment projects
  • Insulated building envelopes
  • Projects requiring a heavyweight 150gsm breather membrane

Its roof and wall compatibility makes Black+ Pro a versatile option where a strong, premium-grade breathable membrane is required across different elements of a building project.

Premium 150gsm Breather Membrane

Novia Black+ Pro has a nominal membrane weight of:

150gsm

Its heavyweight construction provides a strong and substantial membrane for demanding roof and wall applications.

The membrane also provides good tensile and nail tear strength, helping it withstand the handling and fixing associated with installation.

3-Layer Construction with Microporous Core

Novia Black+ Pro uses a 3-layer construction incorporating a microporous core.

This construction combines several important characteristics within a single membrane:

  • Class W1 water resistance
  • Vapour permeability
  • Airtightness
  • Good tensile strength
  • Good nail tear strength

The result is a versatile breathable membrane suitable for both roof and wall applications.

Class W1 Water Resistance

Novia Black+ Pro achieves:

Class W1 water resistance to EN 1928

This provides tested resistance to water penetration while allowing the membrane to remain highly breathable.

The combination of water resistance and vapour permeability makes the membrane particularly suited to insulated roof and wall construction.

Highly Breathable and Vapour Permeable

Despite its Class W1 water resistance, Novia Black+ Pro remains vapour permeable and highly breathable.

This allows water vapour to pass through the membrane as part of an appropriately designed construction, supporting moisture management within insulated building elements.

Airtight Performance

Novia Black+ Pro is also specified as airtight.

When correctly installed and appropriately sealed, the membrane can help control unwanted air movement through the building envelope.

Particular attention should be given to:

  • Membrane overlaps
  • Joints
  • Edges
  • Corners
  • Openings
  • Service penetrations
  • Roof junctions
  • Wall junctions
  • Interfaces with adjoining materials

Appropriate membrane tapes and sealing products should be used according to the relevant installation requirements.

Novia Black+ Pro for Pitched Roofs

Novia Black+ Pro meets EN 13859-1 for pitched roofing and is suitable for both pitched cold and warm roof applications.

Its heavyweight 150gsm construction provides a combination of:

  • Class W1 water resistance
  • High breathability
  • Vapour permeability
  • Airtight performance
  • Good tensile strength
  • Good nail tear strength

This makes it a premium breather membrane option for demanding pitched roofing installations.

Suitable for Cold and Warm Roofs

Novia Black+ Pro can be incorporated into both pitched cold roof and pitched warm roof constructions.

The exact position and installation of the membrane will depend on the complete roof build-up and project requirements.

The membrane should be installed according to Novia’s technical guidance and the requirements of the complete roofing system.

Novia Black+ Pro for Insulated Walls

Novia Black+ Pro also meets EN 13859-2 for wall applications, making it suitable for use within insulated wall construction.

Typical wall applications can include:

  • Timber frame walls
  • Insulated framed walls
  • New-build construction
  • Refurbishment projects
  • Residential buildings
  • Commercial buildings

Its vapour-permeable construction allows moisture vapour to pass through while providing Class W1 resistance to water penetration.

Good Tensile and Nail Tear Strength

Novia Black+ Pro provides good tensile and nail tear strength.

These properties are particularly useful during handling, positioning and fixing, helping provide a robust membrane for demanding roof and wall installations.

Care should still be taken during installation to prevent unnecessary punctures, cuts and tears.

Tested for BS 5534 Wind Uplift Requirements

Novia Black+ Pro has been tested for BS 5534 wind uplift requirements.

Wind uplift requirements can vary according to factors including the roof construction and geographical location.

The relevant Novia technical guidance should therefore be consulted to determine the appropriate fixing and sealing requirements for the individual project.

BS 5534 UV Guidance

Novia Black+ Pro should be installed in accordance with BS 5534 UV guidance.

The membrane should not be assumed to be designed for indefinite exposure to ultraviolet light.

Exposure during installation should be managed according to the appropriate technical guidance.

Class E Fire Classification

Novia Black+ Pro complies with:

EN 13501-1 Fire Classification E

The membrane should be specified as part of the complete roof or wall construction according to the fire performance requirements of the individual project.

UKCA Roof and Wall Standards

Novia Black+ Pro is specified as:

  • UKCA to EN 13859-1 for roofs
  • UKCA to EN 13859-2 for walls

This allows the same membrane to be used across appropriate pitched roof and insulated wall applications.

Black Face and Grey Reverse

Novia Black+ Pro is completely black on one side and grey on the reverse.

The membrane contains no printed text or images apart from an integrated 150mm overlap line.

150mm Overlap Line

The incorporated 150mm overlap line provides a convenient installation reference when positioning adjoining membrane sheets.

The actual lap and sealing requirements should follow Novia’s installation guidance and the requirements of the specific roof or wall construction.

1.5m x 50m Roll

Each roll measures:

1.5m wide x 50m long

Providing a nominal area of:

1.5m x 50m = 75m²

Actual usable coverage will be lower once required membrane overlaps, cutting, penetrations, detailing and general installation wastage are taken into account.
