heat loss

Brad White_9

Not sure of the insulation that may be applied to the inside ("the outside log look") but assuming it is a conventional log cabin I take the core wood thickness as a constant. Forget the "bumps", just the common thickness within each log.

Say you have 8-inch logs and a core thickness of 4 inches of softwood (R=1.25 per inch for a material transmission of 5.0). Plus your indoor and outdoor air films (0.68 and 0.17 respectively). Total R would be 5.85.

"u" factor would be 0.171 for the wall assembly.
