The infrared camera offers a non-invasive means of
monitoring and diagnosing the condition of buildings - providing immediate
high-resolution thermal imagery, revealing potential structural and
moisture issues, energy efficiency and even rodent or pest discovery.
All objects have a certain temperature and emit waves
of energy called infrared radiation. Hot
objects emit more energy than cold objects. A
thermal imager translates these energy waves into a viewable image, which
shows a "heat picture" of a scene. On the
screen of a thermal imager, hotter objects show up at
one end of the color scale (generally a lighter color) and cooler
objects show up at the other end of the color scale
(generally a darker color).

In this example, Thermal Imaging shows that this
whole house ventilation fan is a large thermal bridge between the
hot attic and the conditioned interior below. The temperature of the
entire surface of the louvers is approximately equal to the temperature
in the attic – on hot days, this temperature can be as high as 120°.

Here, uninsulated canned lights provide a
thermal bridge between the hot attic and the conditioned interior.

The IR Camera vividly displays the effects of an
uninsulated attic access door - a
significant thermal bridge between the hot attic above and the
conditioned space below.
