Abstract: The invention relates to a method of producing foam slabs having a density of 20 to 20 to 200 g.l and a cross-section of at least 50 cm by extrusion and foaming a mixture from a styrene polymer, 3 to 15 % by weight of a foaming agent mixture and preferably 0.01 to 10 % by weight of graphite particles, each based on the styrene polymer. The foaming agent is a mixture of 79 to 28 % by weight of CO2; 50 to 10 % by weight of ethanol; 11 to 22 % by weight of a saturated or unsaturated, aliphatic C3-C5 hydrocarbon, preferably isobutane, and 0 to 20 % by weight of water.

Abstract: A roof consists of a flat surface (1), a water and vapor tight cover (2), a heat insulating layer made of extruded polystyrol foam plates (3), a cover (4), and a wind protection layer (5). The heat insulation layer consists of at least two layers (3a,3b), and the upper surface is structured and has raised and lowered areas.
