Standard Test Methods for Evaluating Water-Resistive Barrier (WRB) Coatings Used under Exterior Insulation and Finish Systems (EIFS) or EIFS with Drainage

Importancia y uso:

4.1 This series of test methods provides a means to evaluate performance of the water-resistive barrier coating when subjected to various physical and environmental conditions. The water-resistive barrier coating is applied between the EIFS and substrate in an EIFS-clad wall assembly and is intended to provide additional protection to the building and its contents from incidental moisture intrusion that may occur through the building envelope. Although protected from direct weather exposure after the EIFS is installed, the coating must be durable and weather resistant as it is subjected to various environmental conditions prior to application of the EIFS as well as while the system is in service.
