Disclosed is a self-adhered, vapor permeable, air barrier membrane that is easy to install. The air barrier comprises a spun-bond, non-woven polyolefin sheet coated or partially coated with a pressure sensitive adhesive. A removable release sheet covers the adhesive layer. The membrane has a ...
A permeable building envelope permits vapor diffusion, while a hygroscopic building envelope can absorb and store water from the surrounding air. The study found that a vapor barrier did not significantly change the moisture content of the wall system. Moreover, of the four mechanisms for moisture...
AIR-SHIELD SMP is a self-adhering, vapor permeable, air/liquid moisture barrier that is designed to be fully bonded to the substrate without the use of an adhesive or primer. AIR-SHIELD SMP is a tough, durable membrane that exhibits excellent resistance
A building wrap membrane comprising a sheet of spunbonded polypropylene fabric member with integral pressure sensitive permeable adhesive coated on the back of the member and a drainage matrix secured to the front surface of the member, the drainage matrix being comprised of individual thermoplastic th...
Vapor permeable (greater than 10 perms):Unpainted drywall and gypsum board, Tyvek™, Typar™, and other house wrap materials. Conclusion: Understanding the roles and proper installation of air barriers and vapor barriers is vital to the health and longevity of your home. For more details on...
PRODUCT DESCRIPTION: TK-AIRMAX® 2104 VAPOR PERMEABLE is a water-borne, elastomeric, liquid membrane, vapor permeable air barrier used to restrict air movement and protect concrete, masonry, exterior gypsum and OSB board. TK-AIRMAX® 2104 VAPOR PERMEABLE forms a solid barrier against air ...
referred to as weather-resistive barriers or air barriers, but most house wraps are vapor permeable,” says Lamberti. “On the other hand, a properly sealed polyethylene vapor retarder installed in a closed and conditioned crawlspace can be considered both a vapor retarder and air barrier.” ...
A slab-on-grade or basement floor should be poured over a cross-laminated polyethylene vapor barrier over 4" of permeable fill to prevent wicking of moisture from the ground (and radon)(concrete is hydrophilic). See alsoInfiltration HVAC References...
Non-permeable Membrane Engineered to help control indoor climate by reducing air leakage and uncontrolled airflow through the building envelope and by preventing moisture ingress. 3M™ Air and Vapor Barrier 3015NP product details A smarter approach to air and vapor control ...
