Lou correct. Adding radiant barrier is a COMPLETE waste of money and has zero affect on adding value.
wlj, correct as well. securing the wires in the wall cavity being foamed is a MUST. When the foam expands it will lift the wires right out of the cavity and sure enough, they will be cut when the foam is trimmed.
I know this sound trunkslammish, but we use duct tape to secure them to the studs (not the OSB back wall as it doesnt stick worth a crap. Explained to the builder and home owner that its a temporary "mount" and they have no problem with it. The insulators LOVE following our low voltage installs as they NEVER cut wires anymore because we take that extra step. Not that I have ever had wires melt, but it stands to reason the duct tape may help that? No idea.
We tried nailing but if you dont nail/secure them every freakin feet they sure do get expanded with the foam. Cheesy as it sounds, duct tape is a simple solution that just plain works. We often will not tape them until the day before foaming which sometimes requires a return trip but not big deal. In texas, if we leave they duct tape there for a week it sometimes can come unsecure thus rendering the effort worthless.
Ahhh, duct tape. The redneck answer to everything. lol
Lou, 8 tons in a spray foam house?? Never heard of such. Does sound like overkill. One of the great benefits of foam is it drastcially reduces the tonnaged needed on a house. No offense but it sure sounds like it was not calculated right by the AC company. Maybe they are not familiar with foam? Happens all the time. Some dont get it. Once I had to show an AC man actual white papers to prove him wrong.
