Air And Water Resistive Barrier

A one component fluid applied vapor permeable air water resistive barrier optimized for airless spray application.

Air and water resistive barrier.

What is a water resistive barrier. A water resistive barrier is a thin membrane typically 5 to 15 mils thick 005 to 0 015 in. Integrated barriers like lp weatherlogic air water barrier remove the need for multiple materials in an exterior wall assembly. 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.

According to the usgbc. A single material can function as all three an air vapor and water resistive barrier. Or 0 13 to 38 mm which is intended to resist liquid water that has penetrated behind the exterior cladding. There are also materials that function only as a water resistive barrier that are not air barriers.

Understanding the functions of the materials used is critical so that the building performs in accordance to the project requirements. High performance air and water barriers resist air and water intrusion which reduces the amount of moisture vapor in the panels. Waterproof and resilient it may be spray roller or brush applied directly to approved wall substrates. Function of a water resistive barrier.
