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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUnlike traditional vapor retarders, MemBrain helps prevent mold by sensing and adapting permeance to varying humidity throughout the year to keep the wall cavity dry\u003c\/li\u003e\n\u003cli\u003eFor use with un-faced insulation as a vapor retarder (aka vapor barrier) in climate zones where one is required\u003c\/li\u003e\n\u003cli\u003ePrevents moisture vapor from entering the wall cavity in the winter\u003c\/li\u003e\n\u003cli\u003eAllows any moisture buildup to escape the wall cavity in the summer\u003c\/li\u003e\n\u003cli\u003eInstalls like poly with an extra level of moisture protection\u003c\/li\u003e\n\u003cli\u003eGuards against moisture\u003c\/li\u003e\n\u003cli\u003eUnique, patented product\u003c\/li\u003e\n\u003cli\u003eFor use in walls, ceilings, basements, exterior walls (on interior side of exterior wall)\u003c\/li\u003e\n\u003cli\u003eThe right insulation can save on energy and heating and cooling bills\u003c\/li\u003e\n\u003cli\u003eKeeps walls dry - providing assurance for optimum insulation performance\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CertainTeed","offers":[{"title":"Default Title","offer_id":46331008647303,"sku":"EJD5036714","price":166.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/0774\/7207\/files\/5036714.jpg?v=1793085627","url":"https:\/\/www.storeseven.com\/products\/certainteed-902008-membrain-8-ft-w-x-100-ft-l-air-barrier-and-smart-vapor-retarder-roll-833-sq-ft","provider":"StoreSeven","version":"1.0","type":"link"}
