Thermal insulation of the house outside: is it profitable?
In numerous countries, it is difficult to picture the winter with no heating inside the buildings. Unfortunately, many people say that costs of the heating are very high.
One way to deal with it is to wear several jumpers at home. In fact, a more reasonable way to solve that issue and reduce the heating bills is external wall insulation. Of course, it is not needed in every case.
When is it needed?
Many older buildings are badly insulated. These days, constructions normally include insulation, but earlier it was not that natural. Prior to applying the proper material, the detailed expertise ought to be conducted. The specialists can examine which walls need to be taken into account and how great the depletion of warmth is.
Which material to decide on?
Later, the components must be chosen. The most common are polystyrene foam and mineral wool. The choice should be consulted with the firm that sets up the insulation. Normally, wool has good acoustic insulation and because of that it can be used in loud areas. It has higher fire resistance too. Polystyrene has lower tendency to absorb water. These two materials are rather low cost. Of course, there are further options, for instance polyurethane foam, however they are more expensive.
