Fluid Applied Air Moisture Barrier

If the air barrier doubles as a vapor retarder or water resistive barrier additional characteristics must be considered.

Fluid applied air moisture barrier.

Liquid applied acrylic vapor permeable air barrier. Available at distributors nationwide. Meadows proudly offers the air shield line of fluid applied air barriers. Air shield lmp stops the movement of air while at the same time allowing the passage of vapor.

Fluid applied vapor permeable air barrier. Air shield lmp is also a single component liquid applied vapor permeable air liquid moisture barrier. Generally air barriers with a high permeance rating are desired to avoid trapping moisture within wall assembly. One component fluid applied air water resistive barrier that can also function as a class i vapor retarder provides secondary moisture protection behind most wall claddings including brick siding and metal panels.

Fluid applied air vapor barriers. However fluid applied systems sometimes perform numerous roles in a wall assembly. Various formulations are available including low temperature vapor permeable and synthetic rubber. It is acrylic based and cures to a tough monolithic rubber like membrane that resists air leakage and water penetration when applied to plywood and gypsum sheathing concrete and concrete masonry units.

They provide a continuous air vapor barrier in above grade wall assemblies and are ideal for use on cmu walls with imbedded masonry ties and similar applications where detailing with sheet membrane is difficult. The product is designed for wall assemblies that need a vapor permeable air barrier. Products in the line are engineered to meet voc regulations across north america. Sikagard 535 liquid applied acrylic vapor permeable air barrier is a low voc single component liquid applied elastomeric membrane designed to provide a vapor permeable air and water barrier when applied to above grade wall assemblies.

Ccw fluid applied air and vapor barriers are rubberized asphalt membranes applied by spray or roller. A vapor permeable membrane with long term uv resistance henry air bloc all weather stpe is a single component moisture cure silyl terminated polyether stpe water resistive air barrier. Fluid applied air water resistive barrier and water vapor barrier vb is a fluid applied air and water resistive barrier that stops air and water leakage in cavity wall masonry veneer construction as well as in stucco eifs and most other building wall assemblies.
