5.2 Wall Construction:

The test specimen consisted of 3-5/8" x 1-1/4" x 18ga steel stud, EPS foam, metal lath and plaster "Fibrecote" load bearing wall system constructed onsite with a 24" x 24" nominal horizontally centered vinyl fixed window and typical wood 18" exterior eave overhang. Two 3-5/8" 18 ga metal studs with 1-1/4" legs were installed 36" from each edge, leaving a center 24" stud space to facilitate the window installation. The PVC fixed window was interior glazed with 3/4" insulated glass with a 1/2" spacer and two pieces of 1/8" annealed glass set with glazing compound and a snap-in interior glazing bead. The custom manufactured EPS foam insulation panels were joined together using the steel studs in a typical "male-female/tongue and groove" application. The window installed directly to the steel studs as typically done in fixed window installations, no flashings, weather/flashing tapes or building wraps were used with the Imison walling system. Metal lath was secured using 18 ga galvanized tie wire wrapped around the studs passing through the EPS foam and then looped around the metal lath. 1" thick final coat custom formulated plaster "Fibrecote" was sprayed in two separate applications of ~1/2" to each side. The wood eave was then installed to the exterior face. The exterior and interior surfaces were painted with PPG #17-921 Seal Grip primer and PPG #4-110 Perma-Crete Pitt-Flex Elastomeric topcoat. See ATI Test Sample Selection Report E2027.01-801-42 for more fabrication details. 5.3 Drainage: No drainage was utilized.

5.4 Building Wraps, Flashings or Flashing Tapes: No flashings, weather/flashing

tapes or building wraps were used with the Imison walling system.

6.0 Installation: The test specimen was installed into a 2 x 10 Spruce-Pine-Fir wood frame with no shim space to hold the wall specimen and allow the connection of 2 x 4 supporting legs. The 2 x 10 has nothing to do with the performance of the system. The exterior perimeter of the wall specimen plaster/Fibrecote to the 2x10 wood frame, plaster/Fibrecote to the window frame, and plaster/ Fibrecote to the wood eave were sealed with elastomeric sealant.

7.0 Test Results: The temperature during testing was 18°C (65°F). The water application rate was 5 gal/hr/ft2. The results are tabulated as follows:
