I bought a new home and they used sprayed insulation on the outside walls. I would like to run some wires but remember the installer telling me it will be very difficult. So anyone done this? How did you do it and was it a PITA?


I have a home network system that was installed so there is already wires running through this stuff that they put in before the sprayed. Not sure if that helps me or not?


Thanks for any feedback!


Edit: Everything I'm reading sounds like it's not ideal to try and do this. If so I need to figure out a way to run surround sound wires behind my couch in my game room. Guess I could pull carpet and punch a small hole in carpet for wires? I can't seem to find blue tooth connected speakers anywhere besides the soundbar subs. I'm looking for a 5.1 setup.

I don't have the sprayed, but I've read it's pretty easy to pass a straight run through it, same stud cavity, using a steel fish tape (and I assume fiberglass rods).

And, the foam may not even be filling the entire stud cavity. Might just be 3" thick.

What do you mean "same stud cavity"?


Oh and it is packed all the way. I saw it during a walk through during construction and they pack it in there all the way!

Meaning the same vertical space between studs ( a 'stud bay'). You can probably poke/fish vertically with some practice by staying next to the underside of the drywall. But leaving the stud bay is going to be a challenge. That would probably be the cue for the expert to come in...


If you have a path around the room, you could hide wires behind crown molding, poking into the drywall at the top and down (within the stud bay) at the entrance/exit points (the amp location and the speaker locations).

There are two kinds of spray foam, open-cell and closed-cell. Open-cell is soft and spongy and you can easily push a rod or fish tape through it. Closed-cell dries hard as nails. Im sure with enough work you could push something through closed-cell but it would be a serious pita. You should know what you have if you touched the stuff during construction.
