Rigid foam insulation electrical wiring.

Nema approved wiring is compatible however it may be necessary to run speaker wiring network cabling and other services after foam is applied to avoid problems with unrated wiring.

Most homes are insulated using batt or roll insulation.

There are outlets in the knee walls so wires will have to penetrate somewhere. After the wiring is in place the insulation can be laid in. With this approach my big question is. What do i do about the wiring in those wall cavities.

With my friend s basement i plan to use grooved 1 or 1 5 rigid foam board. This is for fire safety. Standard one half inch sheet rock will follow. Push the insulation batt back into the wall with the cut line aligned with the electrical wire.

Another aspect of spray foam insulation with respect to electrical wiring is its capacity to block moisture a definite advantage with electricity. Other options such as spray foam or loose insulation are also a possibility but in all cases the insulation needs to be installed after the wiring is done. I will secure the foam board on to the poured concrete slab walls with 1x3 furring strips via a powder actuated gun and drive pins. Unfold the paper tabs running along the length of the batt.

As it is industry groups have conducted several decades of extensive testing finding that spray foam insulation does not affect electrical wiring when safely applied and installed. I m thinking about adding 2 inches of rigid foam over the studs leaving the fiberglass in place.
