Now strangely, one of the more interesting topics building with logs has to do with ordinary interior sheet rock walls. Inside our cabin we need to have as much light as possible (did I mention we have no electricity?) so we need to have painted sheet rocked walls. And we also need a place to run electrical wires and plumbing. Why electrical wires when we have no electricity? Because the code guy tells me he's worried about the next fellow who lives in this house. It would be tragic if he had no wires in his walls. Go figure.
The interior walls are just normal 2x4 framing. The only tricky bit is how to make the connection with the log walls. There are a couple of philosophies to that. One is to saw a 9/16" grove in the logs that the sheet rock or paneling can slip into. If you have built a chinkless house or any other method where the logs will settle, this is the method you must use The other is to cut the sheet rock close and cover up the gap with some sort of flexible trim. (like nice white nylon rope about 3/4" diameter) Plumbing and wiring goes into these walls just like in any other house. Passing from floor to floor can be a bit of a challenge.
In my case, I tried a little different approach. First we taped the logs with blue masking tape and plastic so the sheet rock just barely overlapped the tape. This will allow us to spray texture and paint on the sheet rock without getting anything on the logs. Then we scribed and cut the sheetrock to fit as closely as we could and nailed it to one side of the 2x4 wall.
After the first side was done, we went around to the other side and filled in the gaps with short pieces of 2x4 and 1x4 and foam. The foam was cut off flush so we could have good support for the sheet rock that went into these chinking grooves.
The second side was sheet rocked the same way as the first. Then we laid a bead of caulking (paintable) into the remaining crack. The wall was then textured and spray painted and then the masking tape was cut away where it intersected the wall. Bingo! A flexible airtight fit. But you can only do this if the logs are not going to settle anymore. Dan Blanchard, the fellow who did all this work, didn't believe me when I was telling him they wouldn't. He was shaking his head the whole time. I figure since the logs have been in place for 8-9 years already it was a safe bet. I guess we'll see.
