Built a log house last year and still have six months left for the logs to settle. I'm finding in the cold weather lot of areas for draughts which is common until settling is complete. However most seem to be around the windows. I'm wondering what is the best mastic type product to fill small gaps and also expandaible foam for behind window boards.
Thanks.
