Using thermal imagers in the summer

Started by John Snell. Last reply by Tyson Pischel Jul 8, 2011. 5 Replies

Too many thermographers leave their imagers in the case during the summer. This comes, in part, from the way we used to work when imagers were not nearly as sensitive and our understanding of how to use them was limited to winter work.Get the darned…Continue

Looking to buy a thermal imaging camera soon. Want to know what is the best one out there for the features and price?

 

Thanks

No, despite what some suggest, it is not a simple process to determine R-value or otherwise quantify heat transfer based on a single thermal image. Still, images can be very compelling and other tests can fill in the numbers.
Comment by Hal Skinner on May 26, 2011 at 8:02pm

That was what I had somewhat envisioned for that test.

 

One room in a home.  Half the wall painted with the coating and half with regular paint and thermal picture from the outside to show the heat energy reduction.

 

The 2nd test would be painting the coating on a section of a wall and regular paint on the EXTERIOR wall, again both on the same wall of a room - half and half, to show the reduction.

 

What I am most curious to see is if what it shows on the thermal picture can be measured in some form.  Or, is that going to require other measuring equipment to determine exactly what % of reduction we are looking at in the thermal picture.

 

What radiation / heat energy they see on one half vs what they see on the other.  Can a thermal inage akone determine that?

Comment by John Snell on May 26, 2011 at 7:50pm

Hal, One of the issues you run right into using thermography to show the impact of insulating coatings is that the imagers SEE radiation. Thus if the coating reflects radiation in the wavelengths detected by the imager, you'll see that but that doesn't necessarily show how effective the coating is. Better to paint some of the interior wall surfaces and leave others unpainted and then look at the wall from the exterior; of course this assumes all walls are same construction (except the coating) and that all thermal influences on both sides of the wall are similar. 

I know some folks have tried this sort of test but I'm not convinced they "dotted all their i's and crossed all their t's" if you know what I mean.

It might be more effective to design a demonstration on a smaller scale, say a couple of cardboard boxes with the same internal heat source. If the coating actually reduced heat transfer, it would show up on the exterior side. John N. is correct, however, in that most people would not accept a couple of cardboard boxes as good science!

Comment by John Nicholas on May 26, 2011 at 12:04pm

Hal,

 

If you set it up so you could follow a standardized testing protocol, such as RESNET, ANSI, or ASTM perhaps you could make a claim.  Would your claim be accepted by the building performance industry?  Some would, some wouldn't.

 

Your best bet to establish a insulative value for any product claiming to retard heat transfer is to pay an independent lab to do a guarded hot box test on it.  That will actually measure the heat loss per sf in each sample.  The test is repeatable, and is not subject to interpretation.  With this independent test, you can get DOE, RESNET, BPI and other entities that are recognized within the industry to use the information.

Comment by Hal Skinner on May 26, 2011 at 10:57am

Hi Michael.

 

I have a question;  How exact a science is thermal imaging?  I have many years working with an insulating coating but ZERO experiences with thermal imaging.

 

Hypothetical situation;  If we painted an insulating coating on the interior sheetrock of a home, say we painted half a wall, I would expect a themal image showing a reduction in the loss of heat through that wall to the outside colder air.

 

Is thermal imaging an exact enough science so that those images can be analyzed to determine the exact amount of heat loss reduced and thereby calculate it's equivolent R-rating? 

 

Thanks and my apologies if this sounds like a dumb question.

I apologize that I have not posted anything interesting the group lately... but I have been a busy guy!   However, I attended ACI Northwest this week down in Portland, Oregon and had a great time.   On Monday of this week, I had an opportunity to perform a fun infrared inspection and blower door test with some other colleagues on a south Portland home.   I will share some of the images as soon as I get a chance to get them out of my Ti32 imager.  I also strongly encourage all other members of this group to post examples of your work, ask questions, and prod us into meaningful discussions.
