Why is the external wall insulation so relevant while erecting a house?

Depending on the thermal insulation qualities of the walls, their dimensions and the method of heating the building, energy worth several thousand zlotys each year can slip away from the house.

For various shareholders, this is a sufficient argument to take into consideration insulation of walls.
In most cases, the walls may be isolated in a pretty easy manner. It is normal that restoration will lead to considerable sums, but the effect will be not only smaller heating bills, but also increase the aesthetics of the building. If the building was still constructed in the previous way, it can be almost clear that it needs thermo-innovation. But external wall insulation may may be required in buildings build later – when during the contruction the layer of isolation implemented was too light. In both occasions, the renovation should be anticipated by an energy audit. This is a study conducted by specialist organizations, allowing not solely to figure out how much warmth escapes from the house, but also to exactly mark places that equest special attention. The part of the audit may as well be the thermovision test. The following step is to select the methodtechnique of isolating the walls. At this stage, many shareholders are wondering which insulation to choose. The great majority of structures in our country is warmed with styrofoam or mineral wool. Both substances are featured by similar thermic insulation qualities.

A substitute to wool and styrofoam are polyurethane or polyethylene foams. Due to the rather elevated cost, they have not yet got much recognition, although they have many benefits.
