One of the main applications of the sprayed polyurethane foam is the subsequent prevention of drop case or the air moisture barrier together with the heat and rain water insulation of agricultural and livestock buildings and warehouses. With the help of PUR foam, the large temperature fluctuation can be eliminated, the growth of the animals influenced. We are to imagine again that a pig the food eaten in winter used to his increasing and not for heat production. The sprayed polyurethane foam cannot be warm through the summer, as it has excellent material properties. So that we can prevent the great heat to make the animals appetite or even get a heat stroke. The corresponding temperature produces significant revenue increase in livestock or in poultry breeding.
