Patent ID: 8225565

Claim:
An insulation system for a natural log cabin, the system comprising: a plurality of natural logs each positioned horizontally in a vertical array of single natural logs stacked one on top of another to form a wall, each of the natural logs having a top log contacting surface and a bottom log contacting surface for contacting adjacent top and bottom logs with the sides of the natural logs exposed, each of the natural logs having an elongated insulation slot cut through the natural log from the top log contacting surface to the bottom log contacting surface and extending along a substantial portion of the length of the natural log leaving a solid log end portion at each end of the natural log to maintain the structural integrity of the natural log and to form a corner joint with a similar orthogonal wall of natural logs, the insulation slot of each natural log aligning with the insulation slot of each adjacent natural log to form a vertically aligned array of insulation slots aligned in the vertical stack of logs to create a full wall interior insulation space to receive wiring, plumbing, and insulation in the interior insulation space to form an insulation system for a natural log cabin having the interior insulation space sufficiently thick to be filled with a sufficient thickness of insulation to meet or exceed insulation requirements, the insulation not being visible and only the sides of the natural logs exposed on the exterior and interior of the wall; a series of spaced vertical structural posts inserted vertically in the interior insulation space; a first means for adjustably attaching a top end of each of the structural posts to a top natural log in the wall and a second means for adjustably attaching a bottom end of each of the structural posts to a bottom foundation so that the structural posts adjust at the ends to bind the logs of the wall together to provide structural integrity to the wall and to eliminate any spaces between adjacent logs; a series of horizontal cross plates installed in a spaced array along the top log contacting surface in recessed notches, each of the cross plates spanning the insulation opening, each of the cross plates comprising a rigid planar plate having a post opening therethrough positioned in the interior insulation space to support one of the vertical support posts therein and a plurality of fastener holes therein to receive wood screws into a lower log and at least one upwardly protruding spike to stick into a bottom of an upper log installed over the lower log to secure the logs together.
