In a traditional building, the plaster is actually the airtightness layer of the house. An important consideration here is that the best layer is interrupted as little as possible. Usually the plaster stopped behind a flush toilet or a bathtub that leak entails. The masonry is in fact only windproof, not airtight.

This is obviously not the only one. Other issues are the connections of the roof on the exterior walls and the connections of the windows and doors in the outer walls. For this purpose, there are special tapes that it be applied in the plaster and thus complete the low air density.

The E level can easily be 10 points lower in an air-tight envelope. The EPB legislation default assumed a pretty bad situation. Usually scored to take a home without special measures already Stukker better than the default value.
