We're in the middle of a renovation of a 2 story 1912 Colonial.
Currently, the kitchen and dining room are gutted down to the studs. The kitchen area was a porch at one point and had been closed in. It has a mismatch of small plywood and press board pieces over the studs followed by wood siding. The dining room just has wood siding and no underlayment.
The issue is that there are gaps where you can clearly see light. Some other rooms had something resembling tar paper tacked between the wall studs covering any gaps. Does anyone know if this is common or if there is a preferred way to seal up the wall? One of the kitchen walls is westward facing and will take the brunt of rain storms, winter winds etc. The wall was insulated with fiberglass, but it was cold in winter - now I know why.
Any suggestions would be appreciated.
