Log Homes are VERY fire resistant.
It has been proven in scientific research that Log Homes are quit resistant to fire. The reality is that the logs are large enough in diameter that the fire can not get a firm grip on the source of the fuel. The conclusion reached by Dr. Dalibor Houdek included the following statement: "A large-sale laboratory test showed that a massive wooden wall with considerable numbers of lateral wood-to-wood joints can maintain the fire safety requirements for as long as 172 minutes. The log wall withstood 180 minutest (3 hours) from its integrity and insulation viewpoint, and 172 minute from the point of its load-bearing capacity." Source: Log Building News, Sept. 2001
If you would like to read more extensively on this issue, I suggest starting on the paper by the Log Homes Council of the National Association of Home Builders title the Fire Performance of Log Walls.
