The Onduline Ondutiss Air 120 Breather Membrane (50m x 1m) is a high-performance, 120gsm vapour-permeable roofing underlay designed to protect pitched roofs and timber frame walls from moisture, wind-driven snow, and dust. This 3-layer polypropylene membrane acts as a waterproof barrier while preventing condensation build-up by letting internal water vapour escape.
