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. or 0.13 to .38 mm) which is intended to resist liquid water that has penetrated behind the exterior cladding.

Function of a Water-Resistive Barrier

A properly installed water resistive barrier (which includes proper flashing over doors and windows, continuity at seams, and sealing around penetrations) will improve the overall moisture efficiency and performance of the home or building’s wall system by providing a secondary moisture drainage plane. Water resistive barriers resist bulk water penetration and wind-driven rain that penetrates the exterior cladding from intruding into the wall assembly. Water will be channeled down the outside surface of the water resistive barrier, thus reducing the potential for condensation build-up in the wall assembly which reduces the likelihood of moisture problems, rot and degradation.

Water-resistive barriers come in a variety of widths and lengths as well as a variety of materials. These materials consist of polymeric-based sheets (plastic) and can include spun-bonded (fibers), cross-woven (tapes), film (sheets) or a combination thereof.

A water resistive barrier is different than Grade D building paper (paper-based). Most commercially available polymeric-based water-resistive barriers are highly moisture-resistant and therefore, do not absorb water like typical Grade D or felt building papers. Polymeric water-resistive barrier are typically stronger than Grade D or felt building papers, thus they tend to have better durability than conventional building papers.

Water-Resistive Barrier Test Requirements for ABAA Listing

Water-resistive barrier materials have product-specific test properties that they have to test to including dry tensile strength or dry breaking force, pliability and water resistance ensuring they will meet the needed requirements during their service life. The link below to the ABAA Process for Approval will outline those test properties further. Please see the test results below for ASTM E96 values.

For a water-resistive barrier material to be listed on the ABAA website, the manufacturer shall complete the evaluation criteria process outlined in the ABAA Process for Approval of Water-Resistive Barriers (WRBs) document. Once a manufacturer has demonstrated to ABAA that their material meets the established criteria and has completed the process of submitting test reports and supporting documents for their material, they will be listed in the table below as an “ABAA Evaluated Water-Resistive Barrier” and included in the appropriate ABAA Master Specification.
