Have ThermaSteel Panels been fire tested?

Yes! The panels have been systems tested with thermal barriers for surface burning characteristics, smoke development, room fire tests, and hourly fire test ratings, as per building code requirements. Panels have been tested as a wall system with gypsum wallboard thermal barriers for 15 minutes, 1-hour, and 2-hour fire ratings. Most codes require a 15-minute minimum interior thermal barrier. Paper auto-ignites @451F. Wood, depending on its species, auto-ignites @ approx. 904F. Fire tests have proven that EPS gives off fewer toxins than conventional wood framing. UBC Std. 17-5, ASTM E 119. ThermaSteel panels have been tested as a wall system with gypsum wallboard thermal barriers for 15 min., 1-hour, and 2-hour ratings.
