Thermal Imaging is often
used to identify and highlight areas of heat loss in buildings,
in order to improve or correct insulation. In order to
visualise this heat loss successfully, we need to fulfill
survey is best be carried out morning or night. This
is because during the daytime, sunlight (both direct
sunlight and sunlight that has been diffused through
cloud) causes infra red reflections on the property which
can mask the subtle emissions we are looking for, and
it can confuse the picture, as parts of the structure
that emit heat may also absorb heat well, and so in daylight
they show up much darker than areas of the building that
reflect light well.
the survey should be carried out in cold conditions.
The colder the better as the greater the difference between
the exterior of the house and the outside air temperature,
the more clearly the heat emission will be seen. In practical
terms, you won't get much value out of a survey done
when outside air temperatures are above 15°C. Ideally,
you want the survey done when outside temperatures drop
lower than 15°C.

PREPARING A THERMAL SURVEY
In order to maximise the difference
in temperature between the building and the outside air,
we recommend that the house is heated prior to our visit.
Ideally, the house should be heated for 10-12 hours to
a comfortable room temperature (18-20°C), but particularly
during warmer weather, there may be extra benefit in
heating the house to a higher temperaure - say 25-27°C.
It is important that the house is heated for several
hours prior to our visit - this allows the fabric of
the building to warm up, which requires considerable
time. It also allows any heat losses in the ceiling of
the upper floor to heat the attic sufficiently to show
up minor heat loss through the roof covering.
We will photograph your property with
our thermal imaging camera from various angles. We would
normally expect to produce around 10-15 good quality images
of the building. Other areas of interest may also be photographed
at the same time if required (eg underfloor heating system,
boiler, hot water cylinder, insulated pipes etc). We generally
aim to complete a thermal survey in around 30-60 minutes,
depending on the inspection requirements.
