Abstract: A process is proposed for production of composite elements (12) having at least one outer layer (14) and an isocyanate-based rigid foam (16). The outer layer (14) is moved continuously, and liquid starting material for the isocyanate-based rigid foam (16) is applied to the outer layer (14). The liquid starting material for the isocyanate-based rigid foam (16) is applied by means of at least one fixed tube (18) provided with openings (20). The liquid starting material comprises at least one compound that reacts with isocyanate groups to form urethane, and a polyisocyanate and a blowing agent. The blowing agent has a boiling point of +15°C to +250°C at atmospheric pressure. The compound that reacts with isocyanate groups to form urethane or the polyisocyanate is laden with at least one fluid having a boiling point lower than +15°C at atmospheric pressure under a pressure above atmospheric pressure.
