How much should I be worried of living in a house with spray polyurethane foam insulation surfaces under the floor tiles?
Recently a few surfaces of spray polyurethane foam were installed in
our home, for insulation
purposes. There is going to be a heating system, based on pipes
running hot water (~30 C
degrees), above the SPF surface, and above it they will place the floor tiles.
Currently the house is completely empty and fully ventilated (there
are no windows yet) and it will take around additional 6 months until
we will enter it, but I am still worried about potential off gasses
coming from the stable SPF surface even after that time.
The below EPA link discusses ASTM WK30960, a future method for
determining volatile organic compounds, diisocyanates, oligomeric
isocyanates, and amine catalysts emitted from SPF insulation products
designed for on-site application in buildings, but the knowledge about
this is still limited:
From what I see, most of the concern is during the period of time this
insulation is not yet fully cured, and 6 months may or may not be
enough time for it to be fully cured (the vendor claims it
takes seconds but I don't really trust him...).
I keep getting completely different opinions about this and feel I
need to consult with someone who really understand chemistry and
materials, and who will maybe know this material a bit more. I also keep reading horror stories about this material.
I talked to our vendor, and they have never performed any
tests for offgassing from this product. They said they never heard any
requirement to do that.
How much should I be worried? Is there any test I can/should do? Or
would I better just remove those SPF surfaces and ask for some other
insulation which should be safer (couldn't find one yet) ?
From what I understand, this material is vastly used in the US, Canada and Europe, but I'm not sure this is
enough to be calm..
Thanks a lot!
