Air and Water Infiltration

  1. Air infiltration in accordance with ASTM E 283-73 and water penetration in accordance with ASTM E 331-70. Reference Construction Consulting Laboratory Report Jan. 25-Feb. 1, 1988
    A steel stud framed assembly measuring 8 ft. x 12 ft. was clad with StoneLite®travertine panels. The panels were attached with Dow Corning 795 structural silicone. Joints between the unfilled travertine (natural voids in the stone) were also sealed (caulked) with Dow Corning 795 structural silicone sealant. The StoneLite® assembly successfully passed air infiltration and water penetration tests both before and after thermal cycling temperatures between +180 F and -20 F. After passing the 30-psf-design load and 45-psf overload, the simulated negative wind load was taken to 180 psf (equal to 265 miles per hour).
  2. Air infiltration in accordance with ASTM E 283-73 and water penetration in accordance with ASTM E 331-70. Reference Construction Consulting Laboratory Report September & October 1988
    A steel stud framed assembly measuring 9 ft. – 6 in. wide by 17 ft. high was clad with varying types and sizes of StoneLite® marble panels. These panels were attached with T-nut inserts bolted to connection clips and welded to the framing. The assembly successfully passed air infiltration and both static and dynamic water penetration tests before and after thermal cycling temperatures between +210 F and – 10 F. Structural testing was terminated at 88 psf simulated negative wind load when a clip connecting the steels stud framing to the test chamber twisted and failed. There was no panel failure.
  3. Addendum: April 22, 2008 we had Architectural Testing, Inc. (formerly HTL) conduct testing to renew our Miami-Dade certification. In this report in Section 6.1 Protocol TAS 202-94 Static Air Pressure, we have results for Air Infiltration and Water Penetration:
    • Air @ 1.57psf (25mph) Results: 0.019 cfm/ft²
    • Air @ 6.24psf (50mph) Results: 0.052 cfm/ft²
    • Water Penetration: 15% of Positive design Pressure Results: 13.5psf Pass
