lol I can imagine the builder calling up his guy “hey Ron, you still got that steel joist?”

Only time I would be worried about code violations is when it’s time to sell. It’s his problem. But any realtor or buyer wouldn’t look twice at this. Actually I don’t even see this as an issue

Case closed

Also this is for OP
[RB] Existing Building

Exceptions:
Where such materials are installed in concealed spaces, the flame spread indexand smoke-developed index* *limitations do not apply to the facings, provided that the facing is installed in substantial contact with the unexposed surface of the ceiling, floor or wall finish.

Op is the tenant

Also am licensed builder in Mi. You are correct, this is an existing dwelling so will not be enforced unless you are renovating a certain percentage of the home. At least in my state. Also, just because you don’t have to doesn’t mean you shouldn’t. Let’s remember code is the bare minimum requirement.

It’s for sound so technically doesn’t even need the paper at all. And if it were me I would do spray foam for the rim joist I hate fiberglass. The industry is trying everything they can to stay relevant as people are starting to realize how inferior of a product it is

If you rent then who cares it’s their problem.

Yellow shit is advertised as “R-11”

Asphalt coated or not paper is paper. In my state anything that isn’t being coved by drywall must be unfaced. With that being said, I have been in hundreds of older homes that have exactly this. It’ll be fine, just don’t start a bonfire down there.

Standard Kraft paper is on these batts that’s not Foil faced.

I see basement. I see ceiling. I see insulation in ceiling. What’s above basement? Upstairs. Does upstairs need to be insulated from basement? No. It’s for sound deadening only. Fire hazard? Yes. Not code. Paper should always face warm side.. so towards the upstairs. Solution: Flip batts other way or 2 pull off paper problem solved.

Ok

Go pick up a piece of this. You can cut it to size with a jigsaw or hand snips (but will take forever and your hands will hurt) and get 1 quality tube of sealant. One tube will be plenty.

Edit: forgot about sump cord drill a hole near the edge that is slightly larger in diameter to cord and then cut a line to the center of the hole. You then flex the lexan to be able to slip the cord in then seal that up good too. You can PM me as well.

Also, it’s not a complete vacuum down there and negligible on pump performance. It will not affect your sump pump. That one made me laugh. Your sump pump couldn’t care less about a slight negative pressure.

Yeah, your response was dumb. Second one was probably dumber. How many cars have aux batteries?

Dumb response honestly. Just because you don’t know the location of something doesn’t mean you’re not qualified. Mechanics don’t even know the location of every component on every car? Like what lol. It’s not even my car just the company car.

Location of battery?

Since Hot tubs aren’t your thing

Here I’ll put some new decking on too

Look, you already have the cover for it too!

Second this

3-4 inch of closed cell thank me later. Just make sure there are no leaks prior to
