13.4 Insulation deficiencies
13.4.1 General
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 correctly installed insulation,
and/or show the area where air is penetrating the frame of the building.
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.
13.4.2 Figure
In the image below, insulation in the roof framing is lacking. Due to the absence of insula-
tion, air has forced its way into the roof structure, which thus takes on a different character-
istic appearance in the infrared image.
