So first I want to say I’m not trying to sound proof I’m trying to lower the noise a lot because of how loud it is just talking in there let alone angle grinding and saws.

So for the orange those are coated fiberglass welding blankets to keep sparks from angle grinding and torch cutting off the wall ( if needed? I did some angle grinding by a window and now it’s covered with bits of steel melted in it ) and hopefully add a slight bit of sound absorption.
I am thinking of hanging the coated welding blankets in front of the garage doors for protection and some hopeful sound absorption as well.

Any other ideas for sound absorption that is hot spark/spatter proof?

So the “Sep wall” is a wall or curtain I’d like to keep the dust and sparks from getting to the other side.
Im guessing I’d need to just build a wood wall and put a door in? Idk of a curtain that will keep the dust out.

Chip saws, tables saws also so cant just tig weld
