Air Vapor Barrier Details

Low temperature application down to 20 f 6 c with no additives required.

Air vapor barrier details.

Air barriers are essential for a high performing building envelope. Options for above and below grade applications are available. Carlisle boasts the industry s most comprehensive line of air and vapor barrier products including self adhering sheet membranes spray and roller applied air vapor barriers and fluid applied vapor permeable air barriers. Meadows system to complete the building envelope.

Air bloc 17mr can be applied down to 20 f 6 c. Self adhesive air and vapor barrier membrane blueskin sa is a self adhering membrane consisting of an sbs rubberized asphalt compound laminated on a blue polyethylene film. They dramatically improve building energy efficiency indoor comfort and longevity. Perm a barrier products help create complete building envelope solutions.

Air barrier materials can also be provided with properties which also class them as vapor barriers. 3m air and vapor barrier 3015 is an air moisture and water impermeable film membrane with an aggressive high tack pressure sensitive acrylic adhesive. The history of cold climate vapor barriers itself is a story based more on personalities than physics. Call us at 800 342 5976.

Vapor barriers are also a cold climate artifact that have diffused into other climates more from ignorance than need. Ccw provides three types of air barriers. The membrane s controlled thickness is fabricated from cross laminated polyethylene bonded to specially modified asphalt. Spray roll or brush applied henry s air bloc 17mr is a one component rubberized membrane that provides an air barrier when applied to a range of construction surfaces.

Keep in mind however sheet polyethylene on the inside of building assemblies in cold mixed. An example of this are self adhered modified bituminous membranes and sheet polyethylene which can be used as both an air barrier and a vapor barrier. It does not require the use of a primer on most construction surfaces. About air vapor barriers.

An excellent discussion about the differences between vapor barriers and air barriers can be found in quirrouette 1985. It reduces air leakage and uncontrolled airflow from the building envelope prevents moisture ingress and helps improve indoor air quality. Air bloc 17mr cures to a tough monolithic rubber like membrane. The products work equally well as air or vapor barrier on precast concrete cast in place concrete masonry concrete block interior and exterior gypsum board styrofoam primed steel aluminum mill finish anodized aluminum primed galvanized metal drywall and plywood.

It is a roll type product that is nominally 40 mils thick. Contractors can apply them easily to most commercial building surfaces including concrete green concrete steel brick and modular vinyl.
