I am a board member for a housing association. We have a problem in one of our apartments, there is a cold draft against the exterior wall, or rather in the corner. The building was constructed in the late 1950s and actually consists of 2 building sections joined together with a small gap in between for movement. It's an apartment half a floor up, and the wall facing the seam has a very strong cold draft. At +1 outside, it was about 9 degrees on that wall with a thermal camera.
From what I've read, the facade has marmoroc blocks, as well as 70 mm insulation (west coast board) and a steel stud to hold everything up.
Could it be that they were set edge to edge at the gap, and the wind barrier placed on top has broken? I'm not sure who to turn to for help with the problem, so any assistance is appreciated.
