"Larry, are they trying to assign blame? If so, it's a bit like blaming the foot for Colin cancer. If this was a prescriptive job and not a home performance job, you can't blame the insulation guy for the homeowners improper operation of…"

Wilfred Skillicorn Jr. replied to Larry Nissman's discussion Foam insulation on attic floor
"Yuck! I would check the basement or crawl space, check humidity levels and see what was under the foam. Also: Who did the work? Were they certified? how old was the Foam? Was the job inspected. What about that  Electric? Lot's of…"

Sean Lintow Sr replied to Larry Nissman's discussion Foam insulation on attic floor
"Long time no hear Bud & good points As for codes - yes it requires a barrier unless the foam meets certain requirements which isn't that big of an issue doing the attic floor as the drywall underneath counts & then you apply blown in…"

Bud Poll replied to Larry Nissman's discussion Foam insulation on attic floor
"You have a BD, that's good.  IR would add another star. @Larry "I would have to think they removed the existing insulation but you never know" Looking at their foam job I wouldn't expect they did a lot of cleaning up. I…"

Larry Nissman replied to Larry Nissman's discussion Foam insulation on attic floor
"I don't know what is under the foam, but probably just the floor deck. I would have to think they removed the existing insulation but you never know. I suspect that the moisture problems are emanating from a damp basement or crawlspace and are…"

"The contractor that did that should have his toys taken away. To answer your general question, applying rigid or spray foam to an attic floor would follow the normal rules of ensuring any surface that can come in contact with humid air must always…"

"Hi Bud. This home is in the North East (NYC Suburbs). We are a mechanical contractor and were called in to do some work unrelated to building performance. The homeowner did complain that since the attic insulation they have been experiencing…"

Bud Poll replied to Larry Nissman's discussion Foam insulation on attic floor
"Hi Larry, what a mess.  Give us your climate zone so we know outside temp and humidity. Did you do a blower door test to see how tight the building is,  I'm wondering where else he might have used that foam? What is in the basement,…"

Sean Lintow Sr replied to Larry Nissman's discussion Foam insulation on attic floor
"The insulation job is quite simply a freaking eyesore & mess - with that it shouldn't be the issue where they are smelling mildew, getting bugs in, etc... (assuming you are talking about inside the house) - put your sleuthing hat on, find…"

"Hi Quinn. I'm first trying to find out if this is considered a bad insulation installation. And if so, how bad. I can send you the image, just let me know how."

"I have to agree with Kurt. 2000 ppm is exceedingly high. I have tested hundreds of hot water heater (NG, Oil) and mostly they come in around 16 ppm. There is clearly something wrong and we all know that a gas hot water draft can easily be…"
