The problem studied in this work is, how porous, absorbent materials surroundning or placed in a room influence the relative humidity of the room. This is of interest in designing precautions and machinery to monitor the indoor climate in museums and dwelling rooms. - A novel technique for the investigation of the moisture buffering capacity of building materials is introduced, measuring the resulting flux in the system instead of the resulting relative humidity.
