Hi,
I read some posts about insulating apartment walls and answers were to put up the foam sheets. I’m doing that for my windows and my front door. Works excellent.

However, I would like to use Great Stuff, spray insulation for my walls because if there is already insulation, it doesn’t work very well.

As far as safety goes, what do I need to know before I start drilling holes in the wall?

Both Great Stuff and the sheets of foam will cost me… I wish I could get it wholesale!

Thanks.
OK, I’m convinced it is not a good idea. Your right, it would take a lot of the product and wires to consider… the clincher was reading about fire hazard.

Thanks!
