My family and I live in a 36 year old tongue-and-groove log cabin. The interior of the house is a flat uniform wall. The exterior logs are somewhat rounded and not uniform. Orignally there was some kind of caulking/insulation strips between the logs in the tongue and grooves. I can feel cold air coming in between the logs. How do I seal/chink the house to prevent drafts without changing the exterior look?
