Air And Water Resistive Barrier

Integrated barriers like lp weatherlogic air water barrier remove the need for multiple materials in an exterior wall assembly.

Air and water resistive barrier.

A water resistive barrier is a thin membrane typically 5 to 15 mils thick 005 to 0 015 in. Function of a 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. Many builders have turned to huber s zip system sheathing a type of osb with a coating of resin impregnated kraft paper.

Waterproof and resilient it may be spray roller or brush applied directly to approved wall substrates. What is a water resistive barrier. Or 0 13 to 38 mm which is intended to resist liquid water that has penetrated behind the exterior cladding. Contact the air and.

According to the usgbc. Understanding the functions of the materials used is critical so that the building performs in accordance to the project requirements. A one component fluid applied vapor permeable air water resistive barrier optimized for airless spray application. There are also materials that function only as a water resistive barrier that are not air barriers.

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