A method for the production of expanded polymeric materials; in particular for producing thermally insulating materials used in refrigerators. The method comprising the steps of providing a mixture of reagents based on isocyanate and polyol with the addition of expandable polystyrene-based microspheres, in which method the ratio by weight between the reagents and the expandable microspheres is between, about 7:1 and about 1:2.
