For various investors, this is a sufficient argument to take into consideration insulation of partitions.


In most cases, the walls can be insulated in a fairly easy way. It is true that restoration will bring about noticeable investments, but the outcome will be not solely smaller heating bills, but also improve the aesthetics of the house. If the house was still built in the old system, it is almost clear that it requests thermo-modernization. But external wall insulation may may be needed in buildings erected later – when during the contruction the layer of insulation applied was too thin. In both occasions, the restoration is supposed to be anticipated by an energy audit. This is a study conducted by expert companies, permitting not only to detect how much warmth escapes from the house, but also to exactly mark spots that require particular care. The part of the analysis can also be the thermovision test. The next move is to select the way of isolating the walls. At this stage, numerous investors are thinking which insulation to choose. The broad majority of structures in our country is warmed with styrofoam or mineral wool. Both materials are characterized by similar thermic insulation properties.




An alternative to wool and foamed polystyrene are polyurethane or polyethylene foams. Because of the somewhat high price, they have not yet got much popularity, although they have many benefits.
