The diploma thesis deals with the comparison of the fire performance of different structural joints used in wooden constructions. The main aim of this diploma thesis was to perform a radial heat treatment with a radiant panel on a CLT panel made of solid wood (connected by gluing with pins) and compare their fire and acoustic characteristics. We analyzed the material structure of the CLT panel together with the plasterboard, the material structure of the CLT panel together with polystyrene and plasterboard. For these material compositions, we calculated the sound absorption coefficient based on the reverberation time. From the material samples measured, the best value of the sound absorption coefficient was the sample of the CLT panel and the plasterboard. In the radiant heat test, it was better able to withstand the CLT panel of glued joints, on which we observed smaller changes in structure than on the pin CLT panel.
