Thermal insulation of the walls outside: is it profitable?

In many countries, it is hard to picture the winter without heating inside the buildings. Unluckily, many people complain that costs of the heating are very high.

The first way to deal with it is to wear several layers of clothes at home. In fact, a more reasonable way to solve that problem and reduce the heating bills is external wall insulation. Of course, it is not necessary in all cases.
When is it needed?
A lot of age-old constructions are badly insulated. Nowadays, buildings’ construction normally incorporate insulation, but some years ago it was not that natural. Before applying the proper material, the detailed expertise should be done. The specialists may check which walls should be taken into consideration and how great the loss of warmth is.
Which approach to pick?
Next, the components have to be chosen. The most common are polystyrene foam as well as mineral wool. The decision ought to be discussed with the company that sets up the insulation. Generally, wool has improved acoustic insulation and because of that it may be used in loud areas. It has better resistance to fire as well. Polystyrene has lower wettability. These two materials are rather cheap. As expected there are further options, for example polyurethane foam, but they are more expensive.

After several years it turns out that this decision had been good. Finally, the elevation looks refreshed and more aesthetic. What more could anybody want?
