Neoprene foam pipe wrap off gassing?

Member Posts: 6
We've installed a new on demand hot water boiler system for both radiant and baseboards. Our plumber built a custom made heat exchanger wrapped in neoprene foam. We have a funky smell in the new mechanical room that I thought was somehow related to the plumbing system - drainage but I've had 2 plumbers check it out and they don't think that's the issue. I'm just wondering if anyone has experience with the neoprene foam wrapped around the pipes off gassing and making this smell?
Thanks!
Thanks!

Make/model of the insulation is needed. I doubt it's neoprene.0

Many construction materials "off-gas". Solvents and plasticizers evaporate, paints will emit ammonia smells or vapors of whatever base they have. Adhesives also can emit odors when heated. More info is needed to give you a better answer0

Determine the brand and look up the data sheet. If it is the rubbery type it may be this

Yes it does give off some smell when you open a box.
The smell does go away after time
How hot are you running the system.
The inexpensive foam type insulation, like swimming pool noodles, tends to melt, dry out and crumble after time, but is usually odorless.

I don't see a name on here. The only thing on the side of the foam tube is 5/8 ID x 1/2 Wall R 3.3 25/50 167 357 1 I think our plumber picked it up at a supply house, not one of the big box stores. It's not like swimming pool noodles, more like rubber. Has a faint odor off one that hasn't been installed but there is quite a bit on the heat exchanger. Haven't been running the system for the past few months but the odor is still there.
As EBEBRATT-Ed and hot rod have suggested, it may be elastomeric and the MSDS says nothing about off-gassing. I really appreciate your time in trying to help, kind of stumped right now...0 -

It is simple insulating pipes which carry hot water from your water heater to faucets. it could be polyethylene or neoprene foam as well as fiberglass wrap0

Anyone have any info on those neat flow-meters in the background?0

Blue & White is one common brand, very easy to read. They were, are, common in the solar thermal industry.

I'm wondering if that foam wrap is the culprit putting out a nasty odor. Seems like it's the worst when I'm in there. There's a louvered bi-fold door between the mechanical and laundry. The odor is strongest in the mechanical room. I was just down there, thinking maybe if I painted the foam it would lock in the odor?
The flow meters are for the hot water returns to the faucets to make sure there is always hot water w/o having to wait.0 -
If that foam was slit to go over the pipes rather than slipping over the open end as you build, they may have used a special glue for sealing the joint. Are the black cable ties there to close the insulation or are they tying wires down.
That glue may have a stronger odor than the insulation itself.
With enough air movement/changes it may subside enough that it may not be so noticeable.1 -
This foam has the self adhesive strips that seal the split shut. You peel off the backing on both strips and they stick together. This install has been in since the beginning of the year. It's either getting a bit better or we are getting used to it. Beats me...0

I'm traveling on business right now but my wife reports that it seems to be getting better! I'm hoping the fumes are dissipating and will go away. I appreciate all the feed back. You folks are great!
Thank you...0 -

Just something you gotta deal with for a bit. You should smell it when you open a new box, phew.
