The water is soaking into the ceiling and causing its temperature to be lower than the rest of the leak free ceiling therefore it is showing up on the thermal camera. You can think of it this way, if you were to place your hand on a wall or other types of solid object and you can feel heat or cold from a source from the other side then a thermal camera is showing exactly what you are feeling but it can do it so much better.
Now, thick walls or well insulated walls do not conduct heat and therefore would likely block out any heat sources completely, which is normally the primary purpose for insulation.
It gets a little but more tricky with some metal surfaces and glass. With shiny and smooth metal surfaces it will end up acting like a mirror and reflect the heat. You might be wondering now that if its a simple as seeing the heat is the same as using my hand then why would I need to spend money on this device?
How often do you touch your ceiling or walls to check for temperature changes? This is where the thermal camera truly shines. It is so sensitive that small temperature changes will be as clear as day through it. Locating leaks and abnormal temperature early on is critical in saving systems and preventing further damage. Furthermore, suppose you had an inkling of a leak happening, where would you begin to open up the boards or punching a hole through a wall to find overheating electrical components?
The thermal camera will point you in the right direction and save you time and money. As mentioned above, it's not possible for any thermal camera to see through any solid object. So how it works is that there is an object or substance that is causing temperature variance on the wall, floor or ceiling.
To check this; a wall, floor or ceiling has a uniform temperature which means that under normal circumstances the temperature is the same across the whole surface. However, if you suspect poor insulation or wish to detect pipes behind the wall, this is possible. Let's assume you have the heating on inside a room and its freezing cold outside. A well-insulated house will have uniform temperature across windows, doors, and walls throughout the day. Thermal cameras focus on the infrared heat energy and converts it into colors that represent the different level of heat on the thermal images.
Brighter colors such as red, orange or yellow represent warmer temperatures while darker colors like purple, blue or black indicate colder temperatures. From the image above, you can see that the television and the sofa are warmer compared to other objects.
You can also see that parts of the wall are cooler than others and this is how it can detect what's happening behind a solid object, in this case, a wall. By looking at the infrared image of the surroundings of the house, inspectors can tell whether insulation is needed or not by checking for things such as heat loss or air leakages. Other factors to be considered would be weather conditions or the shape of the home.
To check if there are any gaps in the walls, inspectors would usually perform a test called blower door test, which would be done to check which exact spots causes the air leakages so that the necessary action can be taken.
An Infrared image of the wall will visibly show the drywall screws because of the difference in temperature between the drywall and screws.
The same can be seen for the studs since wood releases heat at the different rate than metal screws and drywall. The temperature range can be adjusted depending on which part you would like to see more details of, whether it be the screws or the studs.
To have a well insulated home, inspections such as energy loss, HVAC, moisture, roof leaks and plumbing leaks should be inspected in addition to just inspecting the heat radiation behind walls. Thermal images can also see the differences in temperatures caused by insects, mold and moisture.
With a good understanding of thermal imaging and the help of a knowledgeable inspector, any insulation problems can be quickly solved. They are mostly used in buildings with many floor and are used most often during the colder seasons.
These hot water supply pipes are not visible to the eye as they are located beneath the floor, which makes it easy to be ignored or forgotten. It is very important to keep an eye out for it and should be monitored on a regular basis, i. Thermal cameras can be used to monitor the situation to make sure the pipes are working properly and efficiently locate if or where the radiant heat leakages exist.
If a radiant heat leakage is present, it can use up a lot of energy and cause major property damage if it is not repaired in time. It can take up a long period of time and a lot of money to identify the exact location of a leaking hot water pipe and it is quite the physical process of tearing up or breaking up big areas of the flooring in order to locate the exact location of a leaking hot water supply pipe if not identified early.
The more time it took to locate the leaking pipe, the more costly and difficult it would be to settle and repair the damages caused. After detecting problems such as leakages, it is important to take action to fix the issue immediately.
This can reduce and prevents further damage which would save you time and money. By identifying the variance in temperature between a wet area and the surrounding dry areas thermal imaging can help locate moisture issues that would not be visible during a limited visual home inspection.
It will reflect back your body instead of what is on the other side of the glass. Pipes in winter — we know it gets cold here in Colorado in the winter. If they do, they can burst and this will cause a leak. Making sure that the faucets drip, pipes are insulated, and the garage door is closed are a few ways to keep this from happening. Water Heater — maintenance of the water heater is important. Fireplace — maintenance of the fireplace is important as well.
Cleaning the soot, chimney, chimney cap are maintenance ideas in the spring or summer before the cold temperatures roll in. Call a professional if you suspect there is a leak in the home, missing insulation, or high temperatures in the electrical areas of the home. An inspection using thermal imaging will give you peace of mind. You want to be safe than sorry. If you find there are areas in which you have concerns, reach out to a professional for help.
Then, this signals to the home inspector that there may be an issue that needs investigating a little bit more. As mentioned earlier, thermal imaging will allow the inspector to see where in a pipe line or attic or the front of the home where there is an issue. This is great because you are saving time from digging up an entire yard or combing an entire attic to see where the issue is. It is worth the money to have this inspection done.

HVAC — to look for leaks in the unit. Electrical — to find electrical issues such as overloaded circuit breakers, electrical faults, open circuits, and loose connections.
It can also be used to find wiring issues. Unfortunately, issues in these areas can lead to an electrical fire. Pest Control — this camera can find termites and other wood-destroying pests due to the heat that radiates from their bodies. Here is a good video about using a thermal imaging camera to find pests:. The system calculates the time it takes for the lasers to bounce back to determine a distance based on the speed of light.
The beams spread through solid objects making it hard to see an accurate image. Also glass and metal absorb LiDAR making it hard to differentiate between objects and the background. No, you can not see through walls with thermal imaging. Thermal imaging works by detecting infrared radiation emitted from objects and converting the signal into a thermal image, where different temperatures are represented with different colors or shades of grey.
So if something were inside the wall, like missing insulation and caused a big enough temperature difference that would be picked up on a thermal camera. X-ray imaging is the process where something is radiated with a specific energy range of electromagnetic radiation.
Then you look at the shadow of the radiation on the other side. Think of X-ray imaging as like shadow puppets. The light is the source, and the hand puppets being used will block the light to form the shadow. The image that you would get would be very difficult since the wall would most likely be one of the most radiopaque items in the path and will just absorb most of the X-ray thus creating the strongest shadow.
Range-R radars. Range-R radar devices are handheld or mounted on a pistol. The device emits a pulse of waves in the direction it is pointing, when the waves come into contact with the wall they bounce back.
