METHOD OF MANUFACTURING A BUILDING ELEMENT FOR THERMAL INSULATION, METHOD FOR FILLING CAVITY WITH INSULATING MATERIAL IN A BUILDING ELEMENT AND BUILDING ELEMENT FOR THERMAL INSULATION

摘要

In accordance with the present invention, there is provided method of manufacturing a building element for thermal insulation characterized in that, the known components for producing an open-cell or a closed-cell polyurethane foam are being prepared. The method comprising the step of supplying each of components separately under pressure towards the hollow space of the block or the likes that mixing both components at the inlet of the hollow space with using of nozzles. The method of components supplying is performed in such a way that an open-cell or the closed-cell polyurethane foam is obtained in the interior space of a hollow block and not before. In further embodiment of the invention, the components are being supplied into the mould for producing shaped profile made of polyurethane foam. The hollow space of the building element is being filled with the profile.
