Performance Evaluation and Research of Alternative Thermal Insulation Based on Waste Polyester Fibers

In the production of building materials the emphasis is put on the utilization of waste materials generated in various industrial processes. The production of secondary raw material increases annually with the increase in production volume that is highly dependent on increasing demand. Based on material properties of harmless raw material the utilization in civil engineering is being search. This paper deals with laboratory examination of fundamental material characteristics such as composition, size, shape and thermal and acoustical properties. This paper is subsequently dedicated to the complexity of making a thermal insulation from polyester fibers and bi-component fibers. The research aims to eliminate the amount of waste going to landfills and expand manufacturing industry of producer. The tests results show that the thermal insulation from waste polyester fibers has comparable characteristic with mineral/rock wool.
