The danger of getting moldy walls is high, especially at edges where the surface temperature is near to the dewpoint or less. This causes a high humidity at the wall surface and it's possible that the wall gets moldy.

To prevent mould there are 2 important points:
The isolation of the wall must be very good, to prevent that the inside wall temperature comes near or below to the dew point. through periodical vetilation the rel. humidity stays at a low level.Our moisture measuring instruments makes it'spossible to analzye this parameters:
With the material moisture meter AD4A it's possible to measure the material moisture in the walls, a rising material moisture can be detected.
With the rel. air humidity sensors LFLT20 it's possible to measure the rel. humidity and the air temperature, the dew point is calculated from the masured values.
With the surface temperature sensor WT7 the wll temperature can be measured. If the wall temperature is below the dew point, moisture and mould will be produced.
