detecting thermal weaknesses with a thermal camera
The Situation
The owners of a semi-detached house wanted to do something to significantly reduce their rising heating bill by finding out just how well-insulated their home is. What they were hoping to find are cold bridges and weak spots in the insulation which can quickly rip a hole in your budget, because they allow the cold air into the building while letting the warm air out. With the cost of heating fuel and gas spiraling and temperatures plummeting to sub-sub-zero temperatures, such information cannot only save home-owners thousands of pounds in the long run, it can effectively make your home a much warmer and cosier place.

The thermographic inspection which the young family wanted to have carried out on their house involves using an infrared camera.

The Inspection
Although infrared cameras are highly-sophisticated pieces of equipment which incorporate all the latest in cutting-edge technology, they are incredibly easy to use. Infrared cameras are designed to pick up the electromagnetic radiation (heat radiation) which each body emits on account of its absolute temperature, and transfer the information they have received into a pseudocolour image. The image displayed gives a clear and accurate picture of the different temperatures within the area that is being inspected.

The entire temperature spectrum should be taken into account when inspecting the image. This spectrum should be selected so as to allow the whole temperature range to be depicted. Several surface temperature values were measured at distinctive points and included by way of example.

In this particular case the conditions were ideal. The temperature difference between the temperature inside the house and the outside temperature was approx. 23C, the weather was just right (overcast with no sunshine) and 8am was just the right time of day to commence with such an inspection. Both thermographic and digital images were taken of the inside and the outside of the house in order to provide a complete and thorough examination.

The infrared camera was able to uncover weaknesses in the building’s insulation at nearly all the windows facing the street in which the couple and their young children were living. The relatively low temperatures which were measured indicate that cold air can penetrate the window frames where dents and compressions could now be perceived. The next logical step would be to instruct a firm that specialises in window construction to check the windows on the basis of the evidence that the infrared camera had provided.

It also took only one look to see that the temperature of an area on the roof was considerably higher than the surrounding section of roof. This was because the brick wall that formed the structure of the staircase was in direct contact with the roof. The builders had neglected to put proper insulation in place in this part of the building. The infrared camera was able to detect the fault immediately and present the findings in clearly representative pseudocolours on the camera’s crisp, crystal clear display.

Thermographic inspections with an infrared camera can provide you with clear and concise information regarding the state of your building’s insulation and show you where steps have to be taken to remedy the problem.

One Response to Using infrared cameras to detect thermal weak spots in buildings

  1. Fluke says:

    Thermal infrared cameras for energy audits offer a perfectly easy way to detect and, with repairs, eliminate energy loss due to inefficient insulation or poor construction thus ensuring that we have the most energy efficient buildings and homes possible.
