Prior to using the proper material, the detailed expertise ought to be done. The technicians can check which walls should be taken into consideration and how meaningful the loss of warmth is.
Which material to decide on?

In general, wool has good acoustic insulation and because of that it may be used in case of noisy areas. It has better fire resistance as well. Polystyrene has lower wettability. These two materials are rather inexpensive. Of course, there are other options, for instance polyurethane foam, yet they are more expensive.
