This research looks into the moisture behavior of different timber-framed external wall structures under Nordic climatic conditions. Wall structures were studied under laboratory conditions using new test equipment built in connection with the study. The behavior of structures can be analyzed under computer-controlled conditions without disturbances. The objective of this study is to find out how different wall structures absorb moisture and also how they dry. The study examines, for instance, condensation and mold risks, the need for a vapor barrier in wall structures, and the impact of pressure difference on the behavior of structures. The study focuses especially on two wall structure types: a cellulose insulation wall with an air barrier and a mineral wool insulated wall with a vapor and air barrier. However, many other wall types have also been tested.
