Had several large openings I needed to seal up from an campsite repair. I packed them with loose steel wool and situated it how I wanted (leaving it uncompressed as best I could) then I injected spray foam insulation through the steel wool.
The problem with steel wool is it quickly rusts and disintegrates so it's better to use brass or copper wool, usually available at places like Home Depot, Lowes, etc.
Thanks for the tip on the copper & brass steel wool. Wondering how much extra to pay verses the regular steel wool?
I've had good luck with this technique. You can find stainless steel or copper scouring pads at the dollar store. The both are durable and seem to work well. The pads come rolled up in a puffy little ball. You can tease it apart and you will have a long sleeve that you can wrap around pipes or wires or just bunch up to fill a hole. At 3 or 4 for a dollar it's certainly worth a try.
