Consider a room with the following dimensions: Width: 7.2m, Length: 6.5m, Wall height: 3.1m. Calculate the moisture flow of the exterior walls for 24 hours and find the relative humidity (RH) at each interface given the below conditions. Compare the results and evaluate the impacts of various types of vapour barriers. Mark the location of condensation, if it occurs within the wall assembly. The exterior RH is 50
1) Polyethylene sheet
2) Foil-faced insulation
3) Spray foam insulation
4) No vapour barrier
