Air And Water Resistive Barrier

Understanding the functions of the materials used is critical so that the building performs in accordance to the project requirements.

Air and water resistive barrier.

Function of a water resistive barrier. Air barrier water resistive barrier vapor permeable vapor retarder 45201 weathertech brochure 2018 r3 indd 2 4 23 18 12 42 pm. A water resistive barrier is a thin membrane typically 5 to 15 mils thick 005 to 0 015 in. Waterproof and resilient it may be spray roller or brush applied directly to approved wall substrates.

Contact the air and. What is a water resistive barrier. According to the usgbc. 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.

Integrated barriers like lp weatherlogic air water barrier remove the need for multiple materials in an exterior wall assembly. Or 0 13 to 38 mm which is intended to resist liquid water that has penetrated behind the exterior cladding. A single material can function as all three an air vapor 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.

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