This paper presents an analysis of the results of studies that relate to the rational use of waste products from the production of slab insulation based on polyisocyanurate foam (PIR). Its use as a filler for structural and heat-insulating materials based on cement and gypsum binders is considered, optimal compositions for obtaining products that meet the required performance characteristics are described.
