The article considers the prospects of the use of recycled polyester fibers (textile tire cord fibers from waste automobile tires) as a raw material for the production of effective thermal and acoustic insulation materials. The research works have been carried out in accordance with standard test methods. The basic properties of insulation materials with recycled polyester fibers (with average density values of 50 kg/m3 , 75 kg/m3 and 100 kg/m3 ) have been studied; the influence of the binder amount on the basic properties of the materials has been studied as well. The results of study of the sound-insulating ability of the developed materials are given. The economic expediency of the use of recycled polyester fibers for the production of thermal and acoustic insulation materials has been analyzed. The semi-rigid thermal and acoustic insulation materials with the average density of 50–100 kg/m3 , the thermal conductivity coefficient of 0.041–0.048 W/(m·°C), the water absorption (by mass) of 24–39%, the normal sound absorption coefficient of 0.2–0.97 (within the range of 500–4000 Hz) were obtained, and the predicted material cost is by 3–5 times less than the cost of traditional insulating materials
