Abstract Introduction: The design of an exterior wall of timber construction where all forms ofplastic can be avoided is not something that is used in today's buildings in Sweden. Thepurpose of the study is to compare two exterior wall constructions where one exteriorwall is used in today's buildings and contains plastic foil. The other wall does notcontain plastic or steam brake.The aim of the report is to compare these two exterior wall constructions from amoisture perspective where the construction without plastic and steam brake is studiedto be able to verify whether it is possible to use this in today's buildings. The questionsto be studied are the following: - What is the basis for the material choices for wooden exterior wall construction? - How do the moisture conditions vary between the selected exterior wall of timberconstructions based on the actual experiment and the theoretical calculations? Method: The study consisted of a combination of qualitative and quantitative methodswhere several collection methods were used such as interviews, experiments andcalculations. The main topic in the study was moisture and with the help of the methodsprimary data were collected, as well as secondary data were collected through themethod literature study. Results: The study showed results how two different exterior wall of timberconstruction vary from each other based on the parameters relative humidity, steamcontent and temperature. The results are reported through tables and diagrams of howthe walls are affected in the worst possible cases regarding moisture surcharge. Analysis: The analysis links the question, the result, and the theoretical frameworktogether. The values presented in the results are linked to the framework wherescientific studies either support or do not support the results that have been producedduring the study. This finally answered the questions that the report was based on. Discussion: This part presents a discussion regarding the results which have beencollected in the study. This section also presents a method discussion containingarguments whether the methods worked or not.
