Depending on the thermic insulation parameters of the walls, their surface and the technique of heating the house, energy worth many thousand zlotys each year can escape from the house.

For various shareholders, this is a plentiful reason to consider insulation of walls.
In most occasions, the walls may be isolated in a pretty simple manner. It is true that renewal will bring about considerable costs, but the outcome will be not solely smaller heating bills, but also increase the aesthetics of the building. If the building was still constructed in the previous manner, it is almost certain that it needs thermo-innovation. But external wall insulation may also be required in structures build later – when during the contruction the layer of isolation applied was too light. In both occasions, the restoration should be anticipated by a thermal analysis. This is a verification handled by expert companies, permitting not only to determine how much heat escapes from the building, but also to precisely point out places that need special attention. The component of the audit can also be the thermovision verification. The following step is to choose the way of isolating the walls. At this point, various investors are thinking which isolation to pick. The vast majority of buildings in our country is isolated with styrofoam or mineral wool. Both substances are featured by similar thermal insulation properties.

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