Energy-saving sole plates
The usual method of wiring a stud-wall house is to drill holes in the center of the studs and string the wire around the perimeter of the building. When the insulation is installed later, the insulation adjacent to the wiring is compressed, lowering its effectiveness.
A more efficient and less cumbersome wiring scheme, which I learned from Larry Medinger of Ashland, Oregon, is shown in the drawing. A V-groove is cut in the sole plate before the wall is assembled. This groove makes an easy run for the wiring and is out of the way. A bead of mastic or caulk under the plate will cut down on air infiltration, a well-known energy bandit.
