Insulated Log House

This completed project consisted of a new addition to an existing older cabin and a partial renovation of the old cabin. A challenging project.


Basement walls are 14" Durisol ICF with an R-Value of R21, sealed with a dimple membrane.

Suspended concrete slab, built from railroad rails with vaulted ceiling in the basement, exclusively built by Tennengau Timberworks. This construction is incredibly strong and will easily support your 9ft concert grand piano or even your pet elephant!

The exterior walls are 8" high by 4" thick Douglas Fir logs.

5.5" Roxul insulation is added on the exterior

ventilated siding made from Larch boards

Total R-Value exterior walls: R26 nominally with the added benefit of thermal mass on the inside of the building.

The roof is all Douglas Fir timbers visible on the inside

2" thick Cedar paneling as the visible ceiling.

All interior walls are 4x8" Douglas Fir.
