FIRE TESTING
STRUCTURAL INSULATED PANELS (SIP's)


Numerous tests have been performed on SIP's and SIP components. These tests include the following:

  • ASTM E-119 One-hour UL Classification U532

  • UBC 26-3 15-minute

  • UL 1256 15-minute

  • ASTM E-84 15-minute

According to current codes and NER-467, panels made with a foamed plastic core must be covered with a 15-minute thermal barrier. This is defined as Y2" gypsum board or equivalent. Equivalent materials could be 5/8" plywood or 1" x 6" T&G. In any event, seek approval on all equivalent materials from local code officials. The Design U532 classification applies to w. H. Porter, Inc., exclusively. Specific instructions relative to installation of Type C gypsum board, use of dimensional lumber splines and joint sealing must be followed.
