Novia Black Plus Essential Roof and Wall Breather Membrane - 1.5m x 50m roll

Novia Black Plus Essential Roof and Wall Breather Membrane is a lightweight, entry‑grade breather membrane designed to provide reliable secondary weather protection while allowing moisture vapour to escape from insulated wall and roof build‑ups. It is suitable for both pitched roofs and insulated wall systems, making it a versatile choice for modern construction. This membrane is a 92 gsm, three‑layer construction with a microporous core, offering W1‑class water resistance and high vapour permeability. One side is fully black, the reverse grey, with no printed text — ideal where a clean, unobtrusive appearance is preferred.
