WickRight Vapor Permeable Membrane is the breathable layer at the heart of the WickRight passive ventilation system — a building membrane that holds back wind-driven rain at the parapet while letting interior moisture vapor escape through the vent path.
It is mechanically fastened to the parapet substrate beneath WickRight metal flashings and vents. Vapor permeability of 108 per ASTM E96 lets moisture vapor rise through and exhaust to the exterior; the membrane resists 19.1 psi of direct water pressure and held 8 oz of standing water for 9.5 hours in testing with minimal seepage.
