Full-Scale Fire Tests of Polyurethane Foam Dome Structures.

TL;DRAbstract

This report documents research to determine the behavior and performance of uncoated rigid polyurethane foam (PUF) and of PUF coated with thermal barrier materials in full-scale fires on foam dome structures. Six PUF dome structures were tested for compliance with specified fire criteria and the results evaluated. The research showed that the coated structures complied with specific Department of Defense fire safety criteria, and furthermore that such a coating is necessary to prevent rapid spread of fire. Since the geometry of the test room apparently has no effect on a structure's ignitability or on the spread of fire, it was also concluded that reasonably fire-resistant structures may be built of PUF for housing during mobilization.
