L x 2 mil Air Barrier and Smart Vapor Retarder Roll — a powerhouse solution for modern homes. This single roll covers about 1,033 square feet, giving you a continuous air barrier and humidity-responsive vapor control across attics and walls, with a convenient 10 ft width and 100 ft length.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSmart, humidity‑responsive vapor control\u003c\/strong\u003e: MemBrain isn’t just a vapor barrier. It’s a smart vapor retarder that adapts its permeability based on interior moisture levels. In humid conditions, it allows controlled vapor movement to help dry the assembly, while in drier conditions it tightens to limit unwanted diffusion. The result is superior moisture management, reduced condensation risk, and a more stable, comfortable indoor environment.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDual performance as an air barrier\u003c\/strong\u003e: In addition to smart vapor control, this roll acts as an effective air barrier, helping to minimize drafty seams and air leaks around edges and penetrations. By reducing uncontrolled air movement, it supports steady interior temperatures and lowers energy waste.\u003c\/p\u003e \u003ch3\u003eProduct specifics that matter for planning\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eRoll dimensions:\u003c\/strong\u003e 10 ft wide by 100 ft long; \u003cstrong\u003ecoverage\u003c\/strong\u003e ≈ 1,033 sq ft\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 2 mil\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Attics and Walls\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e MemBrain; \u003cem\u003eFormaldehyde-free\u003c\/em\u003e\n\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSeams:\u003c\/strong\u003e Seams should be sealed with compatible tapes to maintain an airtight barrier\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePackage quantity:\u003c\/strong\u003e 1 roll per package\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eEnergy certification:\u003c\/strong\u003e Not Energy Star certified\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eWhy MemBrain matters for your project\u003c\/strong\u003e: Moisture and air movement are two critical drivers of energy loss and indoor humidity issues. MemBrain’s adaptive permeability helps keep humidity in check while maintaining an effective barrier against drafts.
