This dissertation deals with fire-technical, acoustic and thermal properties of insulation panels made from recycled technical textiles. Observed panels came from automotive industry. The theoretical part offers an overview of recycled textile usage, description and classification of technical textiles, description of observed material, its composition, combustion processes and methods of waste textile management. In the first part, there are introduces also requirements for buildings and possibility of using panels in terms of thermal and acoustic insulation. The practical part consists of methodology for measuring selected parameters. The aim was to determine flammability of the material, combustion heat as well as its reaction to the thermal load of the radiant heat source. Due to the possibility of using the textile panel as an insulation material, its thermal properties and sound absorption has been also measured. Measurements has been performed on samples of recycled technical textiles, which has been treated with liquid retarders or non-flammable facing (Isonem Anti-fire Solution, Ecogard B45, HR Prof, woven carbon and non-woven carbon foil). The test results have showed that after above-mentioned treatment, flame resistance has increased, while significant change in sound absorption hasn´t been noticed. However, thermal properties of the panels have changed significantly.
