Best insulation option where wall will be exposed.

Hi everyone, need to replace the insulation in one wall of my laundry room after a minor pipe burst a few months back. Currently, wall is open with fibreglass insulation, paper, then vapour barrier. I am really not sure of my options here since there is a lot of piping in this wall for my laundry pump, water shutoffs, water softener etc. I was going to use rockwool but with all of the piping this may not be the best stuff to work with.

I guess what I am asking is, what option do I have that will be easy to install with all the piping and still look ok since I am quite sure I cannot cover this wall up. I am looking to put the house up for sale in spring and just want it to look half-decent, but if all I can do is put the vapour barrier back up then that's what I will do. Thanks in advance.

Please see pics:

I'm not a fan of the plastic bag vapor barrier like that. While it would be quite a bit of work to cut and fit it all, I would lean toward rock wool.

If the paper on the insulation is also vapor barrier, then you have two vapor barriers back to back which would not allow moisture to dry through.

The paper is considered a retarder, the plastic is a barrier, for a basement you never want a barrier (plastic) which in the worst case can trap moisture.

Another option, what I do in my unfinished but insulated basement area, is to but up a layer of Tyvek material.

Material is the right height, it;s easy to work with, wont trap moisture and will seal up all the fiberglass fibers!
