Be compared with

Apartments in monolithic houses are much higher than the coefficient of operation than apartments in any houses. Here, panel houses are much behind monolithic houses, practically, in all characteristics. For example, a monolithic house has a high sound insulation coefficient and maintains heat very well. Modern panel buildings of course exceed the old houses in sound insulation, but in order for them to be compared with monolithic houses, they will have to improve for a very long time.
