Depending on the thermic insulation qualities of the walls, their dimensions and the way of warming the house, warmth worth many thousand zlotys every year can slip away from the house.
For numerous shareholders, this is a plentiful issue to take into consideration insulation of partitions.
In most cases, the walls can be isolated in a pretty easy manner. It is correct that renovation will entail substantial expenditures, but the outcome will be not solely lower heating bills, but also better the aesthetics of the building. If the building was still constructed in the old system, it can be quite clear that it requires thermo-modernization. But external wall insulation can also be needed in structures build later – when during the work the layer of insulation applied was too light. In both cases, the renewal should be preceded by an energy analysis. This is a study overseen by specialist organizations, permitting not solely to figure out how much warmth slips away from the building, but also to precisely mark places that require special care. The component of the analysis may also be the thermovision verification. The following move is to select the way of insulating the walls. At this point, many shareholders are wondering which insulation to choose. The great majority of structures in our country is isolated with styrofoam or mineral wool. Both matters are featured by similar thermal insulation properties.
An alternative to wool and foamed polystyrene are polyurethane or polyethylene foams. Due to the rather high cost, they have not yet gained much popularity, although they have many advantages.
