What I learned from taking the infrared thermography course was that there is a “building science” towards using the equipment properly. For instance, the time of day and weather greatly effect the ability to take accurate and reliable thermal images and readings in order to determine what the defect is and the location or source of the problem.

This is a photo of a light switch on the exterior wall. The color selection was set to the iron palette. The orange and yellow areas of the photo represent warm areas, and the dark purple and black areas represent cooler areas. The SP1 pointer was reading 69.7 degrees, and SP2 was reading 53.3 degrees. The dark purple and black areas show that cool air from the outside of the building may be entering through gaps in the buildings envelope. It is recommended that the owner should have the defect evaluated by a qualified contractor so that repairs can be made, if need be.

The use of infrared technology can allow home inspectors to find defects that may have not been able to be found with the naked eye. Though infrared technology is useful, it should not be the only only tool used to verify a potential defect. The inspector should instead use many tools to verify if a defect is in deed a defect, before reporting it to the client.

The Shower Components were inspected and appear to be functional. The amount of moisture found within the shower walls and ceiling around and near the wall and lighting components were within industry standards. The can lighting system does have a gasket seal to prevent moisture from entering the ceiling cavity. Currently, due to the equalization of ambient temperatures from both inside and outside the home, our infrared scanner did not show any additional concerns. Note that under different environmental changes on any given day and time, conditions within the structure may change and possibly reveal a defect that we were unable to detect during our inspection.

Thermal images show surface heat variations on a spectrum unseen by the naked eye. Every object other than Zero degrees emits some form of radiation. This radiation can differ depending on the material being scanned. Emissivity is defined by these fluctuations in each thermal Image. An infrared camera operator must utilize all their working knowledge of each structure, its equipment, and fixtures to understand and translate this type of information.

Since not all moisture intrusions can be seen with the naked eye, it is important to use tools and technology available to further diagnose areas of inspection. The Flir thermal imager helps measure RH and moisture content of materials you are inspecting.

It may surprise some to find out the advantages presented through business branding utilizing vehicle banners. It can increase business dramatically as well as client perceptions of professionalism and reliability. It is easy marketing but must be quality produced if you expect to be received well.

The use of Thermal Imaging (IR) while doing preventive maintenance on electrical components can be a valuable tool. There are various type of cameras used to determine problems. Each has different capabilities for the respected user to facilitate readings, images and final analysis results. The issues that are addressed such as loose or overheated wires, bad connections, overworked or burning motors and transformers and potential arcing can be clearly seen in the thermal images. By following a regular schedule, burnt or seared wires, breakers, disconnects and transformers can be removed and replaced to prevent any future problems. Because thermal imaging spans a wide area during inspection, potential problems can be viewed with greater emphasis. Its non evasive, safer, and can be visually effect tool. Training and experience only improves and enhances a individuals capabilities and helps to that ensure costly and expensive repairs can be mitigated.

The attached picture is of water wicking around the toilet in a master bathroom. Upon further investigation it was determined that this moisture was not coming from the toilet seal or tank, and was in fact coming from a defective shower curtain liner

I chose the insulation around chimneys . A chimney chase that runs from the lowest level of the home through conditioned space and into an unconditioned attic is not only an energy waster. This lack of insulation around the chase opening was be a big source of heat loss and temperature differential leading to moisture , mold and wood rot of the roof sheathing around the chimney.

In this photo and thermal image, of the same general area, there are a few concerns. One, the bright, or hot, areas in the wall and ceiling showing a lack of proper insulation. Two, the dark area on the ceiling indicating possible moisture. Three, the dark areas at the wall ceiling connection, again having potential for moisture.

After reading the article on Thermal Imaging I have a greater understanding of the tool, its purpose, and how to present any findings to the client. This is a fantastic tool that will undoubtedly improve business and reduce the chances of missing important issues within an spection.

The attached photo shows the middle fuse portraying an increased amount of heat verses the othe 2. We recommend the client seek a licensed professional for further evaluation to investigate the current status to avoid a more costly action in the future.

Infrared Thermography Overview for Home Inspectors: Discusses the overal concept of IR. Thermal imaging cameras work by detecting the heat release of systems, equipment and other item that could lead to a determination of future malfunctions. Lighter colors displays a hotter surface areas fdarker colors portrays much cooler surfaces.

There is a possible roof leak in the past. No evidence was found during the inspection of an active leak. The roof had new sheeting and newer shingles. Recommend monitoring of this area during the rain to see if the leak is still active. If water becomes present recommended a licensed roofing contractor to evaluate and repair as needed.

I learned from the article " IR Cameras: Inspecting Roofs" that “Using an infrared camera to locate areas of moisture intrusion and wet insulation is quick, accurate and inexpensive compared to other methods. Since IR imaging allows problem areas to be located before severe symptoms appear, significant damage can be avoided by catching and addressing issues as they develop.”

My FLIR camera allowed me to verify that all heating equipment in this three story house was working properly. I was able to trace all the supply and return lines as well as verify which equipment was served in which order, allowing them to fine tune their comfort. I also uncovered a basement heater which was way over the safe operating temperature, which led to its replacement.

I chose the article: Thermal Imaging Reports. I especially like the idea of taking two different photos of an area in question, so that my client can easily tell where the anomaly has been located. Together with always remembering to verify the cameras findings by other inspection techniques, I think thermographic imaging is going to be big part of my services going forward.

I currently inspected an electric panel box using a thermal imaging camera that I borrowed form my fire department. As a firefighter by trade, we utilize the thermal imaging camera to check for any fire extensions and hot spots. Here I see an electric service panel box with rust around the edges. That may be due to water intrusion or high levels of moisture. Unfortunately, I did not have a moisture at the moment to confirm The breakers were in working condition with no signs of arcing. According to the thermal camera, the temperature range on the breakers were within normal range. I recommend having an electrical contractor come and replace the box.

Thermal imaging camera are a great tool to add to your home inspector tool box. Being a firefighter myself, the thermal imaging camera is an essential tool that we used to detect hidden fires, also called extensions or hot spots. We also use to find bodies during a rescue whether in a collapse or a victim that is trapped in a burning building. Although this tool can be one of the most expensive tool to have, home inspector will benefit with this tool. We can use it to detect any possible moisture intrusion (you can confirm with a moisture meter). Also detect any anomalies in temperature in an electrical service panel. It can detect moisture penetration that the naked eye can not see. It is important to understand that the thermal imaging camera has its limitation. The home inspector just as I do when I’m on duty as a firefighter, should not solely rely on this piece of equipment. Use your other equipment to confirm.
