Why Thermal Imaging Is Important In Building Inspections

Infrared Thermal Imaging

Termites, when in their nests, leads and workings, often create a hotter climate than the surroundings. With infrared thermal imaging, it’s easy to assess the temperature differential on the surface. Therefore, it’s effortless to detect any termite infestation without damaging the walls and early enough before the termites create some significant damage in the area. If the tools are used by the best inspectors, it’s easy to scan large areas fast enough to determine the termite infestation. The technology also comes in handy when identifying moisture ingress, dampness and ventilation issues around the house.

Debunking Thermal Imaging Myths

Over the time we have been in business, we have conducted lots of inspections and researched on various technologies that improve our reports. We adopted thermal imaging to boost our success in identifying termite infestations during our inspections. Of course, just as with any other new innovation, there have been a few cons who have created popular misconceptions about thermal imaging.

Keep in mind that this technology isn’t magical in any way and doesn’t provide a guarantee for finding termite infestations or any hidden defects in your home. However, there are many unscrupulous inspectors who mislead their clients that thermal imaging cameras can actually see through the walls. You should know that the technology is the best addition to any inspection but doesn’t work as a substitute for the experience, skills and knowledge possessed by a timber pest inspector.

Note that, unlike MRI, CAT scan or X-rays, thermal technology doesn’t actually see through walls. Although thermal images might show the framing inside the walls, it doesn’t mean that it works like the rest. Here, the darker lines of the frame will be visible because it drains the heat from the wall sheet thus appearing as a dark sport in the resulting images. Therefore, what you’re seeing are the colder sections of the wall sheeting because of heat drainage and not the actual frame itself.

The technology actually provides a temperature reading on the surface thus creating a picture from the measurements in its view. It also comes in handy when displaying patterns of moisture, especially when evaporating and cooling around the material. Termites often keep a constant temperature of between 28 and 32 degrees Celsius in their environment. Therefore, if there are enough of them, the rest of the place is infinitely cooler and such the infestation presents as a hot spot.

Using thermal imaging to detect pest activity in timber and any defects require experience, skill, training and knowledge. The entire process also takes into account the current weather, climate, the occupancy, the use of the structure, type of construction, wiring, heating and air conditioning, construction materials, plumbing and also the colour.

Moisture Meters

A moisture meter is usually applied to the surface to detect excess moisture present in the plaster sheeting, timber walls or masonry. They are used to identify the conditions that are most likely to attract termites as well as causing fungal decay, especially if there are no exterior signs. It’s also useful when detecting moisture leakage from rising damp or pipes. Any high moisture readings should be investigated thoroughly to determine the exact cause of the problem.

Boroscope Inspection

If you suspect any termite infestation behind your walls, you can confirm it by drilling a small hole in the wall and inserting a boroscope. It’s useful for illuminating the wall cavity. We will view the inside of the cavity using the eyepiece and also rotate the device to get a 360 view. It’s usually done as a follow up as an invasive inspection when a termite infestation is suspected.
