NoMorePly Breather Membrane - 1.5m x 50m roll

NoMorePly Breather Membrane is a vapour‑permeable, high‑performance weather‑protection layer designed for modern façade, rainscreen and cladding applications. Acting as a secondary weather barrier, it prevents wind‑driven rain and surface moisture from penetrating the wall structure while allowing water vapour to diffuse outward. This ensures insulation remains dry, preserves designed U‑values and reduces the risk of condensation within the building envelope.

Lightweight and easy to handle on site, the membrane also provides robust temporary protection during construction before external cladding is installed. When used in conjunction with NoMorePly Fibre Cement Sheathing Boards, tapes and fixings, it forms part of a co‑ordinated, performance‑verified façade system that supports airtightness, moisture management and long‑term durability.

CHARACTERISTICS
