Wind barrier membrane Diffo Proof 2.75 × 25 m 68 m

The Diffo Proof wind barrier fabric is breathable. Air- and watertight, it forms a seal against wind and moisture while still being breathable so that the membrane’s water vapor permeability allows moisture to escape from the structure. Weatherproof Diffo Proof shields buildings and insulation from water, wind and rain already during construction. Diffo Proof and Anticon Diffo underlay together enable implementing an energy-efficient closed underlay and wind barrier system. Joints and penetrations are sealed with the included Sitko Wind wind barrier tape. Diffo Proof is the cost-conscious builder’s choice.
