A Thermal View of the Roof

Last week we talked about how low-slope roofs leak and, as a result, how the water becomes trapped in the roof system—generally in the insulation—accelerating roof failure. According to a survey by the National Roof Contractors’ Association, on average, roofs in the United States are replaced every ten years or less!

A penetration to the [...]

Alien Vision – Hot Athletes, Cool Photos: A Thermographic View of Sports

If it’s a temporary lull
why’m I bored right outta my skull?
Man, I’m dressin’ sharp an’ feelin’ dull
….The Replacements

We all get bored sometimes. I seem to suffer [...]

It looks like the looks were effectively deceptive on this week’s Teaser Infrared Image!

Answer: While this thermal image may have looked like roller bearings on a conveyor belt, that guess would have been way off. This thermal image is of a set of light bulbs in a row underneath a [...]

The View From the Roof

The snow is nearly melted here in Central Vermont. If you are responsible for the maintenance of those low-slope roofs under which we work and live in, this is a great time to get up on the roof and conduct a spring inspection. A simple walkover with an inspection checklist in hand can [...]

Spring is (nearly) here!

Last week we talked about emissivity and reflection, probably the two most talked about issues among thermographers. But that ain’t all we need to talk about! There is a reason engineering heat transfer courses are both long and notoriously challenging. We won’t go that deep into it, but as most of you know, I am [...]

Reflecting on Our Surroundings

Thermographers operate in a different world than all other humans—maybe that explains something about us. Initially, it can be quite intimidating to learn how to Think Thermally™, but most thermographers I’ve known soon find it fun as well as challenging. Even after nearly 30 years of paying attention to the temperature relationships in the world, [...]
