Abstract: Foam boards of high compressive strength are produced by extruding a mixture of a styrene polymer and from 5 to 16% by weight of a blowing agent which contains a) from 3 to 70% by weight of an alcohol or ketone having a boiling point of from 56 to 100.degree.C, b) from 0 to 50% by weight of carbon dioxide, c) from 0 to 88% by weight of a saturated C3- to C5-hydrocarbon, d) from 2 to 90% by weight of at least one fluorinated hydrocarbon which has a boiling point of from -30 to +30.degree.C.
