	In this paper, the influence of raw materials from renewable sources in the form of rapeseed oil-based polyols on thermal conductivity and the cell structure of rigid polyurethane- -polyisocyanurate foams was presented. Bio-polyols were prepared by the following methods: transesterification, transamidization and two-steps method of epoxidation and oxirane rings opening.
