METHOD OF MANUFACTURING A BUILDING ELEMENT FOR THERMAL INSULATION AND A 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 and a building element for thermal insulation prepared according to the method. According to the method the known components for producing an open-cell or a closed-cell polyurethane foam are being prepared, and then the components are mixed and then, before the polyurethane foam is obtained, supplying the prepared mixture of the components towards the hollow space of the building element in such a way that an open-cell or a closed-cell polyurethane foam is obtained in the interior space of the building element.
