| Attention: Kevin Luckhart |
|||||
| Dear Sir: |
|||||
| This is to confirm that we have completed
testing of your rain screen EIFS wall panels for pressure equalization.
The test indicated that with a 12 mm x 12 mm vent, a 2.5 m x 2.5 m
wall panel of 50 mm thick EPS foam, pressure equalized within a minimum
of 93% when tested in accordance with NRC protocol for pressure equalization.
The panels were tested at pressure differentials of 1500, 1000 and
500 pa and cycled at 2, 1 and 0.5 Hz. A formal report will be issued shortly outlining the testing in detail. Should you have any other questions, please feel free to call. Yours truly, INCHCAPE TESTING SERVICES NA LTD. |
