I would like to start by commending everyone for their input in this brainteaser. This is a perfect example of why we wanted to form this section in the NACHI bulletin board. I applaud all of you. There are going to be things that we just cannot explain because of the limitations that we are bound by. However, in future inspections one of you may encounter the solution to this question and will enlighten the majority with your wisdom.
A little bit of tension has erupted on this thread since its inception because of previous posts and I sincerely hope that we can work past this. Everyone has an opinion and a theory. Let’s be tolerant of one another. This is new to all of us and to the rest of the world. There is no expert in this field yet. Those that taught us what we know have admitted that they have achieved where they are by trial and error. We all have a perspective and an opinion. If you post it, be prepared to support your theory. Anyone questioning your theory is not attacking you, rather trying to broaden our perspective.
I did look behind the slip joint but did not see anything.
I’m quite certain that the dew point temperature was well below 85° which was the ambient outdoor temperature.
I tried to find them, but they are on another computer. Basically we’re just looking at one section of vinyl.
I changed it to rainbow to accentuate the scan.
By the way, I have found some better pallets in QuickView versus quick report for some applications. I will post this later in another thread.
As for other than black and white scans, we use what we have to, to depict the point were trying to make. It should be noted that any other setting degrades resolution. But the more you play with your scan, the better you may be able to relate the issue to your client.
The heat at the roofline is because there is a cathedral ceiling. Also there was some deficient insulation in the attic.
The sheathing behind the vinyl seemed rather consistent for normal construction. Good call!
It took thermal scans on the interior wall and did not discover any anomalies from the inside. I could only see the temperature difference on the exterior vinyl siding layer. Good point!
There is no gas line in the wall. The temperature difference appears to be isolated to one sheet of vinyl siding. Good point!
I agree. I gathered as much information as I could. There is no significant deficiency associated with this condition. There was no supportive testing of any kind to direct a further evaluation. We are just trying to see if anyone out there has come across this situation and has found an answer to this situation.
Nothing that I could determine through a noninvasive examination.
I also had these thoughts. Good consideration.
