Abstract

The fire safety performance of sandwich panels currently in use is non-conforming occasionally. In principle, the non-conforming sandwich panels installed at construction sites should be replaced with conforming ones. However, at the construction sites, instead of replacing the non-conforming sandwich panels, they are reinforcing them with several reinforcement methods in order to enhancing the fire safety performance. Typical reinforcement methods are paint reinforcement, glass wool panel reinforcement, and gypsum board reinforcement. In this study, the fire safety performance of these three reinforcement methods was evaluated using Cone calorimeter test and Single Burning Item Test. As the result, the Cone calorimeter test showed a good value only for the gypsum board reinforcement, and the Single Burning Item Test showed a good value for the glass wool panel reinforcement and the gypsum board reinforcement.
