How does one install electrical wire in foam core panels? What about plumbing?
Wiring a foam core wall is not difficult but does require planning. Much of the wiring will be run in the conventionally framed interior walls, but there will certainly be some wiring in the panelized exterior walls. Our wall panels are manufactured with a wire chase as specified height above the sub floor (usually 14"). Wire chases can also be located a counter height for kitchen outlets. The wire can be accessed by cutting outlet openings just above the chase. Vertical chases can be provided, but are often not needed because the wire can be run along a door opening or through interior wall framing.
Plumbing is not normally run through foam core panels. The panels are used for exterior walls, and as in consistent with good building practice, plumbing should be kept out of exterior walls to avoid freezing.
