For extra protection against moisture, the MemBrain Continuous Air Barrier and Smart Vapor Retarder is your weapon of choice. It lets wall cavities dry out, to help prevent mold. In summer, when humidity is high, it increases permeability so that moisture can escape, as air tightness is maintained. In winter, when humidity is low, it continues to block moisture. Use MemBrain with un-faced insulation in place of kraft faced insulation or polyethylene. Not all climate zones require vapor retarders. Unlike traditional vapor retarders, MemBrain helps prevent mold by sensing and adapting permeance to varying humidity throughout the year to keep the wall cavity dry For use with un-faced insulation as a vapor retarder (aka vapor barrier) in climate zones where one is required Prevents moisture vapor from entering the wall cavity in the winter Allows any moisture buildup to escape the wall cavity in the summer Installs like poly with an extra level of moisture protection Guards against moisture Unique, patented product For use in walls, ceilings, basements, exterior walls (on interior side of exterior wall) The right insulation can save on energy and heating and cooling bills Keeps walls dry - providing assurance for optimum insulation performance Energy Star Certified: No Usage: Attics and Walls Vapor Retardant: Yes Number in Package: 1 Sub Brand: MemBrain Thickness: 2 Brand Name: CertainTeed Length: 100 Product Type: Air Barrier and Smart Vapor Retarder Roll or Batt: Roll Width: 8 Coverage Area: 833 Formaldehyde Free: Yes
