How do the connectors perform in fire?
A test performed at a leading fire testing agency in the United States subjected a panel constructed with THERMOMASS fiber composite connectors to 1900 °C (2000 °F) temperatures for 4 hours with no degradation. The temperature, measured on the surface of the wall opposite the fire, rose only 20.8 °C (37.6 °F) during the testing period. The standard for passing the test was a temperature rise of 121 °C (250 °F). The THERMOMASS® Building System actually improved the overall fire resistance of the wall versus a solid cast concrete wall. In separate tests, THERMOMASS connectors installed in only 76 mm (3 in.) of concrete have been exposed to a standard time-temperature profile while subjected to high tensile loads. Even under these extreme conditions, the connectors have withstood over one hour of fire exposure!
