The Genesis log is a big 6"x12" log that gives you that Appalachian feel but with no interior chinking. The exterior surface of the log is rough textured and has a groove at one edge that can be finished with chinking, or without it as desired. The interior surface is smooth and enhances the massive feeling so characteristic in this log style. Dovetail corners complement the look and ensure a tight fit. The logs are locked together with a large single tongue and groove, and a foam gasket and wood-binding sealer are applied between each course before fastening with large lag screws.
