The simulation revealed an r value of 20.5 for the sample cordwood wall. The insulation value of wood varies depending on what type the wood is and how it has been treated. Cordwood walls are not the best natural insulators but can be built to thermal efficient standards.

Concrete homes magazine web search 5/18/2010 The insulation must be at least 50% on the exterior or integral to the wall to count. Log home product literature claims that log walls insulate as well as fiberglass because of the thermal mass.

Compared to a conventional wood stud wall [3½ inches (8.89 cm) insulation. These values have been calculated for a 1 thick dimension stone sample. A 2x6 wall studs r values are measured as, 5.5 x 1.25.

With a true north log home, our patented technology makes our 6” width by 12” height log exceed energy codes in comparison to a conventionally framed home which requires r. 12.03 * this example is just for wood frame construction. Compared to a conventional wood stud wall [3½ inches (8.89.

The center column in the table above lists values for the thermal conductivity of the natural stone types. In a solid log wall, the logs provide both structure and insulation. Compare this to the basic 2 x 4 wooden stud wall, and 2 x 6 foam insulated and sheathed wall with r values of 15.8 and 25.7, respectively.

Steel studs are a more complicated calculation. Drill holes in the sheathing and blow insulation into the empty wall cavity before installing the new siding, and;
