Blueskin® Breather is a self-adhering membrane consisting of a microporous film laminate, backed with a
specially applied adhesive, which allows water vapor to permeate through while acting as a barrier to air and bulk
-High water vapor permeance allows wall assembly to “breathe”.
-Resists hydrostatic water pressure and wind driven rain.
-Excellent adhesion to prepared substrates of concrete, concrete block, metal, drywall, plywood and OSB.
-Self-adhesive system prevents lateral air movement and eliminates the need for mechanical fasteners.
-Bridges crack and joints in substrates.
-Light in weight to provide ease of application.
