Through: 01/22/07. REPORT Date: 02/14/07. Record Retention Date: 02/09/11. Revision 1: 07/28/15. Project Summary: Architectural Testing, Inc. was contracted by Eldorado Stone , LLC, to perform STRUCTURAL testing on their Castle Rock faux Stone veneer products at Architectural Testing's facility in Kent, Washington.

2 Test specimen description and results are reported herein. Test Methods: The specimen was evaluated in accordance with ASTM E 330, Standard Test Method for STRUCTURAL Performance of Exterior Windows, Doors, Skylights and Curtin Walls by Uniform Static Air Pressure Difference (MODIFIED). Test Specimen Description: General Description: Three 8' wide by 8' high wall samples were prepared. Each wall sample was constructed of Douglas - Fir nominal 2 x 4 plates and 2 x 4 studs spaced 16" on center. Each of the intermediate studs was attached to the top and bottom plates with two 3". drywall screws. 7/16" thick OSB sheathing was fastened to the stud wall with 1-5/8".

3 Drywall screws spaced approximately 8" apart. One layer of 60 minute WRB was stapled to the sheathing. The lb expanded metal lath was applied over the WRB with the staples fastened into the studs every 6". A bed of mortar was applied over the lath and allowed to cure overnight. Following the application of the mortar the individual faux stones were applied in the grouted method. The wall samples were allowed to cure for no less than 28. days and then subjected to tests . Test Description: General Description: Each of the wall samples was subjected to positive and negative STRUCTURAL load tests at psf and 60 psf pressure differentials.

4 Loads were held for 60. seconds. Deflection gauges were used to measure the deflection of the wall assembly. Gauges were mounted to the exterior face of the faux Stone in line with the top, bottom and mid-span of the centermost stud. At the conclusion of each load, the faux Stone was inspected for cracking. Net deflections and visual observations are reported below. Page 2 of 4. Test Results: Test Specimen #1 (Installer: ACCS 2): Pressure Net Deflection Observations psf (positive pressure) " No damage or cracking observed (150 mph wind speed). psf (negative pressure) " No damage or cracking observed (150 mph wind speed).

5 Psf (positive pressure) " No damage or cracking observed (153 mph wind speed). psf (negative pressure) " No damage or cracking observed (153 mph wind speed). Note #1: After completion, loads and inspections at psf and 60 psf pressure differentials, a negative pressure differential of 110 psf (207 mph wind speed) was applied and held for 10 seconds. Following pressure release a visual inspection revealed no visible cracks in the faux Stone . Test Specimen #2 (Installer: LPCS - 1): psf (positive pressure) " No damage or cracking observed (150 mph wind speed). psf (negative pressure) " No damage or cracking observed (150 mph wind speed).

6 Psf (positive pressure) " No damage or cracking observed (153 mph wind speed). psf (negative pressure) " No damage or cracking observed (153 mph wind speed). Note #2: After completion, loads and inspections at psf and 60 psf pressure differentials, a negative pressure differential of 110 psf (207 mph wind speed) was applied and held for 10 seconds. Following pressure release a visual inspection revealed no visible cracks in the faux Stone . Test Specimen #3 (Installer: LYCS - 3): psf (positive pressure) " No damage or cracking observed (150 mph wind speed). psf (negative pressure) " No damage or cracking observed (150 mph wind speed).

7 Psf (positive pressure) " No damage or cracking observed (153 mph wind speed). psf (negative pressure) " No damage or cracking observed (153 mph wind speed). Note #3: After completion, loads and inspections at psf and 60 psf pressure differentials, a positive pressure differential of 110 psf (207 mph wind speed) was applied and held for 10 seconds. Following pressure release a visual inspection revealed no visible cracks in the faux Stone . Page 3 of 4.

If SHEATHING Cover the wall surface with a weather-resis- a release agent is present, acid etch, wire brush surface, or tive barrier. The barrier shall be equal to that provided for in use a metal lath and scratch coat.
