PU Foam Can Provide Insulation for Houses

While providing the ideal insulation for wooden houses in Scandinavia, the issue of controlling heating costs has to be taken into account. Two companies have already jointly conceived a solution based on polyurethane rigid foam. Two wooden beams with cross sections of 98 by 47 mm and 40 by 47 mm were placed in a mold and the gap between the two beams was filled with a liquid polyurethane system solution. The mold was then sealed. and cured at a temperature of about 45ºC. After a short period of time, the finished polyurethane mullions can be removed from the molds. The stability of the mixture is ensured by the fact that the polyurethane system adheres very well to the underside of the wood. This technology prevents the creation of thermal bridges between the internal space and the surface. Thus, the insulation solution is greatly improved. The Norwegian Intellectual Property Office has confirmed in writing that it will grant a patent for the invention of this technology. There are parts of the building envelope where relatively dense heat flow and low internal surface temperatures are formed by the temperature difference between the interior and exterior of the building. These parts become […]
