Inspection & Writing Assignment:
Thermal imaging or Infrared technology is a game changer fro home inspectors. It a tool that in my opinion will reduce liability for home inspectors. We can now see what the naked eye cannot. In my attached picture we see that a circuit breaker is overloaded and should be further examined.
Research & Writing Assignment:
Infared cameras used for moisture intrusion is as valuable a tool for a home inspector as I can think of. The ability to see potential moisture intrusion coupled with a moisture meter is a valuable tool for your client. Ten years ago this technology was probably just too expensive for most home inspectors to afford. Thanks to technology you can now simply plug one into your phone.
I almost know I’m wrong; but in the example of the heated water under the flat roof, wouldn’t the water dissipate the heat quicker than the solids would? I need a lesson in thermodynamics here.
Inspection & Writing Assignment:
This IR photo shows cooling on the ceiling of this upper floor bedroom. In this case the roof was unfinished and allowing water to penetrate in several areas of the home. Moisture was present and confirmed with a moisture meter.
Research & Writing Assignment:
Inspecting roofs with an IR camera can be very efficient, if you know what you are doing. Detecting moisture intrusion can be difficult with normal tools and the naked eye. But with an IR camera and a recent decline in ambient temperature, you can see moisture trapped below a recently cooled roof plane. This happens due to moisture retaining heat longer than solids do.
Inspection & Writing Assignment:
On this infrared scan of the attic hatch it was noted that cold air was leaking into the house through the attic hatch. It is recommended that the homeowner installs a weather stripping around the perimeter of the attic hatch to help reduce energy loss and potential moisture concerns. It was noted that there was frost present and prior stains on the attic hatch.
Research & Writing Assignment:
In this writing assignment I looked at two images from the Illustration Gallery that depicted first a picture of a window with a normal camera. The second picture was of the same window using a infrared image. The infrared image showed water infiltration from the window into to the building structure that was not visible to the naked eye. This example shows the value and added detail that is provided by infrared technology.
Inspection & Writing Assignment:
The image shows a 200 Amp Siemens Breaker in “Composition” in S/E Florida. The image was shot with FLIR E8 camera. The top shows 2- 15 amp breakers (AFCIs) that are not at full capacity and are used for area Bedroom 3 and Bedrooms 1&2 (Outlets and Fans) The dead front was not removed to show the reflectivity of the material. Both breakers were tested and reset. The SP-1 temp is 96.1 F. Emissivity is set at 0.95 and Refl. temp is 71 F. Temp scale was set between 76.2 and 98.0 F (Assistance of Photo and FLIR E8 camera via Peconic Home Inspection)
Inspection & Writing Assignment:
I chose to scan an exterior wall in this home to determine if underlying temperature variations might exist. The wall in the image has a ridged crack below the roof truss in the cathedral ceiling family room. There are also visible signs of additional cracks in the drywall surface. The image indicates a cold spot which may be an indication of water penetration from the roof and or exterior wall or a vulnerability in the envelope of the home. Further investigation with a moisture meter will be incorporated.
Research & Writing Assignment:
I viewed the images in the IR album labeled “Window (IR camera)” and the image labeled “Window (naked eye)” to compare the physical characteristics of wall surface between the upper arched fixed window and the lower window which also appears to be a fixed window. There are clear indications of surface damage to the drywall which may be an indication of water intruding into the home. The thermal comparative image reveals a dark patch in the bottom right corner which is indicative of potential water or exterior envelope failure. A moisture meter should be utilized if the equipment is available to the inspector to ensure that moisture is present. Correction of the vulnerability is needed regardless of present moisture or not.
hi just joined the IR training guess this tech is becoming very helpful
