The heat insulation foam is spread either directly on the safety water-proofing foil or onto the slab structure in the attic. After the spraying the foam can be simply fitted to the required thickness. In the case of roof insulation both type of foams can be applied.<\/p>\n
The advantage of the closed cell foam compared to the open cell foam is that it can be sprayed directly onto tiles as it forms a water barrier, therefore there is no need for a separate vapour barrier. This becomes important if the polyurethane foam is sprayed on the existing vapour barrier foil because based on our experience, unfortunately these foils do not provide long-term protection because the permanently high temperature harms these within a short period of time.<\/p>\n
In these cases the humidity directly contacts the insulation that significantly hinders the proper functioning of the heat insulation. In the case of the application of an open cell structure a vapour barrier layer is necessary.<\/p>\n
An 8-10 cm thick closed cell polyurethane foam insulation results in a drastic heating bill saving.<\/strong><\/em><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>
