Air And Water Resistive Barrier

Waterproof and resilient it may be spray roller or brush applied directly to approved wall substrates.

Air and water resistive barrier.

Many builders have turned to huber s zip system sheathing a type of osb with a coating of resin impregnated kraft paper. Understanding the functions of the materials used is critical so that the building performs in accordance to the project requirements. A water resistive barrier is a thin membrane typically 5 to 15 mils thick 005 to 0 015 in. A one component fluid applied vapor permeable air water resistive barrier optimized for airless spray application.

Air barrier water resistive barrier vapor permeable vapor retarder 45201 weathertech brochure 2018 r3 indd 2 4 23 18 12 42 pm. Function of a water resistive barrier. Integrated barriers like lp weatherlogic air water barrier remove the need for multiple materials in an exterior wall assembly. There are also materials that function only as a water resistive barrier that are not air barriers.

The layer beneath the siding the water resistive barrier or wrb is what will protect the plywood or oriented strand board osb sheathing from any water that sneaks in. A single material can function as all three an air vapor and water resistive barrier. 3 proven air barrier air barriers isolate interior and exterior environments and limit the amount of air that can infiltrate a structure or leak out of it. According to the usgbc.

High performance air and water barriers resist air and water intrusion which reduces the amount of moisture vapor in the panels.
