Besides the thermal properties of a building component and their impact on heating losses, its hygric behavior has to be considered, too. Permanently increased moisture content in the component may result in moisture damages. Elevated surface moisture levels in living rooms can lead to hygienic problems and health risks due to mould growth.
In addition, thermal and hygric behavior of a building component are closely interrelated as well as an increased moisture content favors heat losses. The thermal situation affects moisture transport. Therefore, both have to be investigated together in their mutual interdependence; the research field of hygrothermics is dealing with these problems.

For North State Inspections dot org
North State Inspector Jim Bowline is InterNACHI qualified he knows that the true product that NSI sells to their clients is their home inspection report. While your services include the wealth of your training, education, work experience, and even your work ethic – right up until that next inspection, which would include all the inspections you performed just last week and even yesterday – what you leave your client with is your inspection report. That’s why the presentation, format, language, graphics, and even the software you use will combine to create a report that leaves either a positive or a negative impression. It will leave your client with the confidence that they made the right decision to hire you and that you really delivered based on your advertising, or they’ll wonder what they paid for and whether they should get a second opinion.
Infrared (thermal imaging) is an advanced, non-invasive technology that allows the inspector to show homeowners things about their homes that can’t be revealed using conventional inspection methods. Ancillary inspection reports are just as important as the reports you generate for standard home inspections. For something as specialized as a thermal imaging inspection, it’s critical that the information you present meets your clients’ needs for information they can use and act on.
DOs & DON'Ts
The art of an IR inspection is to interpret the results as accurately and reasonably as possible such that your client is given actionable information in order to proceed with necessary repairs. With that in mind, here’s a list of dos and don’ts:
Explain the limitations of thermal imaging, including the fact that, as with any type of inspection, it can’t predict future conditions. However, a roof that is experiencing moisture intrusion which has been detected through thermal imaging will very likely lead to serious structural issues, if left unaddressed.
Explain the capabilities of thermal imaging and how it can benefit your clients. Do you have marketing materials to give your clients that outline the various conditions that can be detected through infrared technology?
An infrared inspection can identify and document moisture intrusion, energy loss, and even unexpected hot spots.
In terms of energy loss, an IR camera can detect:
heat loss and air infiltration in walls, ceilings, floors, windows and doors;
damaged and/or malfunctioning radiant heating systems;
air-conditioner compressor leaks;
under-fastening and/or missing framing members, and other structural defects that can lead to energy loss; and
broken seals in double-paned windows.
In terms of detecting moisture intrusion, an IR camera can locate:
hidden roof leaks before they cause serious damage;
missing, damaged and/or wet insulation; and
water and moisture intrusion around penetrations and at the foundation and building envelope that could lead to structural damage and mold.
IR cameras are equally effective at locating hot spots in the home, including:
circuit breakers in need of immediate replacement;
overloaded and undersized circuits;
overheated electrical equipment and components; and
electrical faults before they cause a fire.
Additionally, based on the color gradients that thermal images provide, an inspector can locate:
possible pest infestation, as revealed by energy loss through shelter tubes left by boring wood-destroying insects;
the presence of intruders, such as rats, mice and other larger pests hiding within the structure and detected because of their heat signature that the IR camera captures; and
dangerous flue leaks, which can lead to carbon monoxide poisoning of the home’s residents.
Offer to re-inspect (for a fee) after repairs are completed. This is the only sure way to determine whether the repair work undertaken by your client and/or his contractor has effectively addressed the issues that your initial thermal imaging inspection discovered.
unduly alarm clients. An area that has been detected through IR as having potential moisture intrusion, energy loss or extreme heat must be further investigated in order to confirm such a condition. Depending on where the problem has been located, confirmation may be difficult, but relying solely on the IR image is insufficient for recommending that your client pull out the checkbook and hire a contractor. It’s the first step in diagnosing a problem.
overwhelm your clients by using technical language that leaves them in the dust. The science of thermal imaging is fairly straightforward, but it requires extensive training, as does the use of the associated equipment. But your primary mission as a home inspector is to educate your clients, not dazzle them with your brilliance or impress them with your expensive camera.
offer to repair problems that were discovered through your thermal imaging inspection if you perform this function as part of your standard home inspection. InterNACHI’s Code of Ethics prohibits this conflict of interest. While offering to make repairs and actually performing them are not specifically prohibited by the Code of Ethics if the IR inspection was performed as part of an energy audit or ancillary inspection, InterNACHI recommends that inspectors defer repairs to professional contractors to avoid even the appearance of a conflict of interest, since this hurts the inspection industry, and the average homeowner will be understandably suspicious of your intentions, as well as the results of your IR inspection, even if they’re legitimate.
