Default Spray Foam - Basement reno

Question for those that spray foamed their basement reno.

I have one wall in the basement to be finished which is the foundation wall for the garage above. The rim joists are not exposed to the outside as they are in a normal exterior wall.

I'm wondering if I have to spray foam that wall as well or can I get away with standard batts?

Yeah, I think that's probably best. Was trying to cut cost.

Any idea what I'm looking at, rough estimate, to spray 3 walls in a room 14' x 30'? Two walls at 14' and one at 30'.

Do I need to protect coax, telephone, and other low voltage wiring from spray foam?

I've heard and read that sprayfoam can burn the wiring but I'm reading conflicting opinions.

No.
I have never had an issue with this.
However sprayfoam does move things as it expands.

And why are you running coax and phone?

Thanks Greg.

Why? Doesn't everyone have at least one coax or telephone cable in their basement?

I have 4 coax running into the house from a dish and runs along an exterior wall going to the panel. Right now its tacked to the bottom of the ceiling joists but I need to remove them to put up a 2x4 wall then will re-route the cables through the studs.

Same for tel cable.

Coax for BELL Sat. Can't use CAT6

Telephone cable was installed when the house was built and is currently feeding an active jack. What's the point in changing it? These are existing lines already in the basement that will be exposed when sprayed.
