SAMPLE APPLICATIONS HOUSING CONSTRUCTION
Faulty construction or poor ventilation?
Moisture on ceilings and walls may be the result of a construction defect. It is however, in most cases, a sign of poor ventilation. A measure of long-term with the data logger can answer the question.
The data logger calculates the difference between the wall surface temperature and the dew point temperature of the room climate. If it turns out that the ventilation was regular and that the walls are still moist (temperature higher dew point at the wall surface temperature), there is a fault in construction or improper insulation.
