ENCLOSURE SOLUTIONS Technical Bulletin CMU-02 Air Leakage and Water Resistance ASTM E2357 and ASTM E331 Scope Statement During testing, the Owens Corning Enclosure Solutions for CMU with Masonry Veneer were subjected to thousands of positive/ negative pressure cycles simulating wind/structural/thermal movement stress testing of the durability of the air/water resistive barrier assembly. The system was tested in large scale simulations of both unpenetrated (opaque) and penetrated wall surfaces. Testing Conducted By Architectural Testing, Inc. 130 Derry Court York, PA 17406 Testing Witnessed and Listed By Underwriters Laboratories, Inc. 333 Pfingsten Road Northbrook, IL 60062-2096 Listed as UL File No. EWS0023 See UL online certifications directory Testing Date March 2, 2015 Test Report No E4153.01-109-44 Test Methods ASTM E 2357-11, Standard Test Method for Determining Air Leakage of Air Barrier Assemblies ASTM E331-09, Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference Specimen Description Test Specimen Size: 96 " x 96 " (64 ft 2 , 5.946 m 2 ) Opaque Wall The opaque wall was constructed from 16" long by 8" wide by 8" thick concrete masonry units (CMU) with 1/2" mortar joints. Heckmann #1300 hook & ladder joint reinforcement and #1300 pintle wire ties were installed every two courses of CMU spaced vertically with eye wires spaced 16" on center horizontally. The CMU base wall was built inside a steel frame and secured to the frame using concrete anchors at each side, spaced 8" on center, into each course. Owens Corning FOAMULAR 250 XPS insulation, 2" thick, 4'x 8', straight edge, was preliminarily secured on one half of the test wall with Plastic Masonry Fasteners (PMF) from Rodenhouse, Inc, and, on the other half of the wall the FOAMULAR XPS was secured with Grip-Deck Masonry Screws and Thermal-Grip ci Prong Washers. Final attachment was made with Heckmann Building Products Pos-I-Tie masonry anchors and Rodenhouse, Inc Thermal-Grip Brick Tie Washers. The XPS insulation joints, perimeter edges and penetrations were sealed with Owens Corning JointSealR foam joint sealing tape. Penetrated Wall The penetrations included a 625 mm by 1225 mm rough opening with a 600 mm by 1200 mm wood frame window blank, a 100 mm by 100 mm HVAC duct, a 38 mm PVC pipe, and two junction box penetrations; one square and one octagon per ASTM E 2357. The penetrated wall was constructed the same as the Opaque Wall, including all joints sealed with Owens Corning JointSealR Foam Joint Sealing Tape. All penetrations were sealed with FlashSealR Flashing Tape.
