Novia Building Wrap Wall Breather Membrane - 2.7m x 100m roll

Novia Building Wrap Wall Breather Membrane - 2.7m x 100m roll

Novia Building Wrap is a dependable, entry-level breather membrane specifically designed for use in all insulated wall applications. Supplied in extra-wide 2.7m x 100m rolls to cover full storey heights in a single pass, this lightweight membrane provides high air and vapour permeability alongside reliable Class W2 water resistance, helping prevent interstitial condensation while shielding the building envelope from wind-driven rain during construction. It is a lightweight, cost-effective wall protection engineered for high breathability across insulated timber and steel frame constructions.

CHARACTERISTICS

• Full-Storey Roll Coverage: Generous 2.7 m width covers standard wall heights in a single horizontal run, reducing horizontal laps, installation time, and material waste.
• High Air & Vapour Breathability: Allows trapped moisture vapour to escape freely from inside the wall structure, protecting insulation and timber framing from damp and rot.
• Reliable Weather Protection: Rated Class W2 for resistance to water penetration (EN 13111), safeguarding the structure against external moisture ingress.
• Clean, Unbranded Finish: Completely plain black on both faces with no distracting logos or text—featuring only a printed 150 mm overlap guide line for fast, accurate alignment on site.
• UKCA & EN Compliant: Fully compliant with EN 13859-2 (flexible sheets for underlays in walls) and listed on NBS Chorus and NBS Source for straightforward architectural specification.

APPLICATION

• Insulated Timber Frame Walls: External sheathing wrap for off-site and on-site timber frame panels.
• Steel Frame (SFS) & Modular Builds: Protective breather layer behind rainscreen cladding, masonry outer leaves, or weatherboarding.
• Refurbishment & Extensions: Lightweight external wall lining for residential and commercial thermal upgrades.
