Each Pan Abode was entirely constructed of milled logs made of Western Red Cedar. The company hailed cedar’s low-expansion properties that include resistant to shrinking, swelling, and warping during drastic changes in temperature. Cedar timber also provides good insulation, an important feature in Pan Abode buildings since the only insulation came from the 3-inch thickness of the cedar logs themselves. The buildings included no insulation within the walls until much later. All of the Pan Abode logs manufactured between 1952 and 1970 in the Renton factory were milled in 3”x6” rectangular logs with flat edges to create a relatively flat exterior and interior wall surface.
