    What is a Breather Membrane?

    Breather Membranes are designed to allow wall and roof structures to release excess moisture vapour into the atmosphere - to “breathe” - without allowing wind-driven rain and dust to penetrate wall or roof structures. They must be installed on the exterior (“cold”) side of any structure - beneath the main outer building lining, roof tiles or cladding.

    It is advised to seal your Breather Membrane with corresponding Lap Tapes for a quality, breathable seal.

    How do I Apply a Breather Membrane?

    A breather membrane should be applied on the exterior side of any wall or roofing structure - under the outer building lining, roof tiles or cladding. It should be fixed at intervals with suitable, permanent fixings and finished with Breather Membrane Lap Tape for the most reliable and air-tight finish. It is best used in conjunction with a Vapour Control Layer applied to the interior of the structure.

    Frequently Asked Questions

    Breather Membranes

    Novia's breather membranes are engineered to allow insulated structures to release excess moisture. These membranes are essential for maintaining the integrity and longevity of wall and roof structures, including:

    Novia Black+ Pro 150GSM

     This high-spec membrane is suitable for both roof and wall applications, providing robust protection against environmental elements.

    Novia Reflex Reflective Breather

    Enhances thermal performance by reflecting heat, ideal for energy-efficient construction.

    Novia FR Class B-s1,d0

    A fire-rated membrane compliant with UK building regulations, suitable for high-rise and standard constructions.

    These membranes not only enhance the breathability of buildings but also protect against wind-driven rain and dust, ensuring optimal performance and durability​.

    Vapour Control Layers (VCLs)

    Novia’s vapour control layers are critical for managing moisture within buildings, preventing condensation, and protecting insulation. These layers are placed on the warm side of the insulated wall, roof or floor to manage internal moisture.

    Novia VC2 AVCL

    Provides excellent moisture management and is suitable for various construction types.

    Novia VC4000 FR Reflective AVCL

    Designed for use in constructions over 18 meters in height, offering enhanced fire resistance and reflective insulation properties.

    Gas and Damp Proof Membranes

    For sites requiring protection against ground gases and moisture, Novia manufactures specialised membranes such as:

    Novia 1600G Radon Gas Barrier

    Protects against radon gas, damp, and carbon dioxide.

    Novia Methane Pro DPM

    Provides comprehensive protection against methane, damp, radon, and carbon dioxide, meeting BS 8485 standards.

    Tapes and Sealants

    Use our range of Novia tapes and sealants to ensure the proper installation and sealing of breather and gas membranes, vapour control layers and building papers, such as:

    Novia Double Sided Butyl Tape

    Used for sealing laps and edges of membranes.

    Novia Aluminium Foil Tape

    Provides a strong seal and additional protection against environmental factors.
