NOCSA Completes Drainage Performance Testing
The purpose of this test program was to demonstrate that for one coat stucco systems where a weather resistive barrier, meeting the requirements of Section 1404.2 of the 2006 International Building Code, is installed behind the EPS foam, adequate drainage of water occurs.
The tests were performed by the association and its members to meet new requirements of the International Code Council Evaluation Service for the drainage plane located behind cementitious exterior wall coverings.
The ICC-ES requires Evaluation Reports issued on or after the effective date of July 1, 2007 and falling within the scope of this criteria to comply with the revised criteria – AC11 – 3.2.10.
The Specialized Testing of Santa Fe Springs, Calif., conducted the tests.
