Process for the production of building products, namely waterproof, weatherproof lightweight building boards and thermal insulation boards made of extruded polystyrene synthetic foam.

摘要

The invention relates to a method and a device for the production of high-strength, pressure-resistant, watertight and weatherproof lightweight panels and thermal insulation panels made of extruded polystyrene synthetic foam using glass fiber fabric melted therein, the melting process pressing the heated polystyrene material through the openings in the glass fiber fabric sheet and this in the softened state Using gravity, place them over the glass fiber threads of the glass fiber fabric mat and so, after cooling, the two elements flow into each other.
