Abstract
The article presents the results of experimental studies of thermal resistance of non-woven heat-insulating materials under cyclic compression. It has been experimentally established that a change in the thickness of materials during cyclic compression leads to a change in the thermal resistance of studied objects. The dynamics and magnitude of the change in thermal resistance primarily depend on the structure, fibre composition and method of producing the material, to a lesser extent they depend on the initial thickness of the material before compression. As a result, a methodology for evaluation the thermal resistance of heat-insulating materials has been developed. The application of developed methodology allows objective selection of non-woven heat-insulating materials at the design stages of building construction.
