"You are correct, Richard. This pattern is not typical of UFF, but that does not mean that it cannot be UFF. What we don't know are the conditions: what is the span of the image? The difference in shading is relatively minor if the span is about…"

Richard Kornbluth replied to Larry Nissman's discussion Strange IR Image
"The pattern doesn't look like the UFFI foam shrinkage I've seen. UFFI foam shrinkage  tends to show horizontal cracks and gaps along the top and vertical edges of the stud space. A small test hole can confirm if it's UFFI. The…"

"Infrared imaging is only one of many tools to be used for assessment, and is very much subject to interpretation. In order to interpret as accurately as possible, one must know a variety of factors. What was the span of the image and what was the…"

Jason Raddenbach replied to Larry Nissman's discussion Strange IR Image
"I think Sean is onto the answer. The blotchyness makes me think they may have used a spray can primer like "Killz" in a can to cover water damage or mold. If they shot it on there thick enough it could create a thermal difference. How did…"

"SW  exposure.  What is outside?  Was it sunny?  Trees?  Large Shrubs?   I have had the shade pattern show on an interior wall. You have a house with a Brick Facade.  That means you must consider the thermal…"

"Mold? Shoot I have a picture of a smiley face on a wall - reason it was sprayed with something & then painted over, but it was enough to create a thermal difference that can be caught via camera only"

Strange IR Image

Did an energy assessment today and captured this image of an exterior wall. I believe the wall is framed, with sheet rock and a brick facade. It is a 1929 vintage home, but I believe there have been renovations. This image is taken on the second floor and is on an exterior wall with a SW exposure. Any ideas as to this unusual…See More

"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…"

Bud Poll replied to Larry Nissman's discussion Foam insulation on attic floor
"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…"
