### **Abstract**

The article presents results from multidisciplinary research conducted with the pur‐ pose of obtaining new material which reduces flammability and is used for the produc‐ tion of rigid polyurethane‐polyisocyanurate foams (PUR‐PIR). During the preparation of the foam recipe, special attention was paid to the ability to lower the flammability and the improvement of durability and thermo‐insulation properties of rigid foams by using the new, non‐halogen polyol. The new boron compound helped obtaining fire‐ safe PUR‐PIR foams, which are characterized by the reduced amount of total exhausted heat, longer time to full combustion, lower amount of produced carbon dioxide and oxide, increased oxygen index and lower maximum burning temperature in shorter time than the reference foam.
