Our 8"x8" Milled-D log is planed smooth on all sides for a beautiful appearance. This log system also features an inserted corner notch and a milled drip edge. These time-tested methods of joinery ensure an air-tight seal that keeps the outside elements outside. 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 lag screws.
