"Ted, Answers don't jump out.  Realizing that the thermal imaging is from blue to red in just 12 deg of difference means that the top plates are colder but most likely not a real big energy suck.  The blower door was 1.5 times BAS so…"

"Sounds like a lot of work for a little reduction in air infiltration. If it could be incorporated with other work in the same area then it would make some sense.  Sometimes chasing little leaks can't be justified. Unless the IR images show…"

"Hi Matthew, The area in question is often a complex of framing details and as you stated, they change with time.  Shrinkage, warping and hidden details behind that soffit can create energy loss that shows up dramatically with an IR image. …"

Soffit Overhang Spray Foam

I have proposed spray foam for my clients soffits after showing him the blue region with my infrared camera.  The client wants additional return on investment calculations for this measure.  I have indicated that this is beyond the modeling capabilities of our software.  Any ideas on how to relay the value of this procedure.Txx.MattSee More

tedkidd replied to Matthew Stewart's discussion 70 year old boiler AFUE?
"I think boiler AFUE is a really tough thing to narrow down.  If a boiler is grossly oversized it will tend to go very cold.  Cycling losses will be huge.  So measuring combustion only tells a very small part of the picture.…"
