Purpose of the work
All too often, we experts and measurement technicians are totally fixated on airtightness issues. Based on three practical cases, I would like to demonstrate that windproofness, minimal convection in the insulation layer, and the convective separation of different structural elements from one another should also be taken into account in order to prevent structural damage.
Method of approach
The topics
- Brief explanation of terms: paths of moisture into a structure, definition of different types of leak.
- Three cases of structural damage from practice:
- Roof renovation from the outside, top floor ceiling, flat wooden roof.
- Possible procedure for determining causes.
- Attempt at conclusions: Which structures, building versions, and local conditions influence the probability of damage?
