Re-insulating exterior basement walls. Unfaced + FSK rolls or Faced FSK
I’ve spent my free time this summer foam insulating my stud cavity perimeters and putting up some poly-iso in the rim joists. I found (dry) mold in the majority of the current insulation batts between the insulation and the facing. Nothing significant, but enough to make me decide to tear it all down. The old owners of our place didn’t take care of it. Multiple leaking windows, cats, etc so I wasn’t necessarily surprised to find it. We’ve since remedied all of the water sources (at least for now).
Code for exposed insulation in my area (Chicago) calls for a flame retardant facing. Sourcing standard batts with an FSK face has been a pain specifically for my 15in cavities. It’s cheaper for me to go with unfaced batts and a roll of FSK.
Other than having to cut and patch sections for any future issues, is there any downside of going with the unfaced batts and roll of FSK?
For reference I have about 550sq ft to cover. Any insight or experience would be greatly appreciated! Thanks.
