To keep in mind
• Reflective objects may appear warmer
or colder to the camera than they
actually are, owing to reflections of
other objects.

Application examples
Insulation deficiencies
General information on insulation
deficiencies
Insulation deficiencies may result from
insulation losing volume over the course
of time and thereby not entirely filling the
cavity in a frame wall.
An infrared camera allows you to see
these insulation deficiencies because
they either have a different heat
conduction property than sections with
30
correctly installed insulation, and/or show
the area where air is penetrating the
To keep in mind
When you are inspecting a building, the
temperature difference between the
inside and outside should be at least
10°C (18°F). Studs, water pipes, concrete
columns, and similar components may
resemble an insulation deficiency in an
infrared image. Minor differences may
also occur naturally.

framing is lacking. Due to the absence of
insulation, air has forced its way into the
roof structure, which thus takes on a
different characteristic appearance in the
infrared image.
Draft
General information on drafts
Drafts can be found under baseboards,
around door and window casings, and
above ceiling trims. This type of draft is
often possible to see with an infrared
camera, as a cooler airstream cools down
the surrounding surface.
To keep in mind
When you are investigating drafts in a
house, the air pressure inside the house
should be lower than that outside. Close
all doors, windows, and ventilation ducts,
and allow the kitchen fan to run for a
