Thermal insulation materials for buildings provide thermal energy cost savings, hence much attention is directed towards improving their performances and construction of new ones. Inorganic fibrous materials - stone and glass wool and organic foamy materials- expanded and extruded polystyrene are dominant on the European market. However, the EU priorities of creating products with improved ecological footprint have led towards research for developing new insulation materials. Evaluation of the performance of insulation materials is a multi-criteria problem, which has to be carried out with respect to: physical properties, health and environmental protection, applicability as building elements and their cost. Recycled textile waste has already found commercial application as insulation material but so far only waste that is easy to open down to fibers has been used. This paper proposes an alternative solution of a new textile structure that will be used for thermal insulation of buildings’ internal walls in order to prevent the loss of a valuable resource, pre-consumer apparel cutting waste. The designed textile structure is composed of polyester fabric apparel cutting waste which is shredded, rather than opened. Thermal conductivity - λ(W/mK) of the textile structure was measured with the Heat flow meter FOX600 instrument. The main goal was to determine the thermal insulation of the structure compared to the standard insulation structures, as well as textile insulating structures in form of fibers. The results of the 10 samples showed thermal conductivity coefficient (λ=0,052-0,060 W/mK), comparable to the values of standard insulation materials (λ=0,030-0,045 W/mK) and the values of insulation materials made from recycled textile fibers (λ=0,039-0,041 W/mK). In addition to the economic benefits, production of this kind of insulation material will have an ecologic benefit by decreasing environmental pollution arising from polyester apparel cutting waste.
