This data set contains raw data, mainly temperature data, from the large-scale fire experiment, named #FRIC-02, with exposed cross-laminated timber on both the wall and the ceiling. This fire test is among the largest fire experiment conducted to date and gave valuable insights into fire spread rates, external heat fluxes to the facade, charring rates of the CLT. More information about the experiment is found in the open-access journal paper with name: "Fire spread in a large compartment with exposed cross-laminated timber and open ventilation conditions: #FRIC-02 - Exposed wall and ceiling".
