FLIR B-Series infrared camera tells truth about walls and facades
Building insulation quality becomes a pressing issue as heating costs
soar. An infrared camera for building applications and the expert’s eye
can do a lot to save on energy.
“Building and floor leak inspections are our main
applications,” says Günther Buchstaller, a master bricklayer and
plasterer who has specialized in water damage assessment and
thermographic inspection and analysis of residential buildings.
Buchstaller is based in Ruhpolding, a resort in the Bavarian Alps, a
region where the building substance of the houses is considered as very
stable. But even there, the infrared camera discovers leaks and
deficiencies that are becoming pricey: fuel oil prices have risen in
Germany by 100% over the last five years. No wonder more and more house
owners are calling Buchstaller for a thermographic inspection.

Infrared cameras show temperature differences over
entire surfaces. The measurement of house façades and walls is based on
the temperature differences of the house inside, outside and the wall
structure. But much depends on the correct camera setting and, last but
not least, the building expertise of the camera user.
Inspecting and Reporting
“Before every measurement of a building object, I
set the reflected temperature parameter to get a temperature measurement
that is as true as possible.” Buchstaller considers this more important
than setting the degree of emissivity, the amount of heat radiation
that is emitted by every object or subject. In addition to scanning in a
proper way, the interpretation of the imagery requires a solid
knowledge of local building techniques, materials and rules. Buchstaller
uses the ThermaCAM Reporter software to provide his customers with a
comprehensive report that includes imagery, description and an advice
for removal of the fault. “I set the camera on a rainbow colour pallet,
so that the customer can better see the temperature differences on the

In addition, the camera provides support in showing
Buchstaller or his business partner Martin Gastager where not to drill
when doing leak surveys or water damage assessments, an asset in a
region where floor heating is common.
Buchstaller has chosen the FLIR B360 infrared camera
: “The camera’s screen size is important, not only for our user
comfort, but also for the customer who finds the technology quite
impressive, the tiltable lens unit is very handy and the camera’s weight
makes working very easy.”

Skyrocketing heating costs and an affordable
technology are opening up new market and service perspectives for
building professionals. Buchstaller says he expects to amortize his
infrared camer a within two years.
