Depending on the thermic insulation characteristics of the walls, their dimensions and the way of warming the house, energy worth many thousand zlotys each year can slip away from the house.

For various shareholders, this is a plentiful issue to take into consideration insulation of walls.
In most situations, the walls can be isolated in a pretty easy way. It is truthful that renovation will lead to substantial costs, but the effect will be not solely smaller heating expenses, but also increase the esthetics of the house. If the building was still built in the old manner, it can be almost clear that it requires thermo-modernization. But external wall insulation can may be needed in structures build later – when during the contruction the layer of isolation implemented was too thin. In both situations, the renovation should be preceded by a thermal analysis. This is an investigation handled by expert companies, allowing not only to detect how much heat slips away from the house, but also to exactly indicate places that need special care. The component of the analysis may also be the thermovision test. The following step is to choose the way of isolating the walls. At this point, many shareholders are wondering which isolation to choose. The huge majority of buildings in our country is insulated with styrofoam or mineral wool. Both substances are featured by similar thermal insulation qualities.
A substitute to wool and styrofoam are polyurethane or polyethylene foams. Due to the relatively high price, they have not yet acquired much recognition, although they have several advantages.
