Thermal Imaging to Visualise Building Heat Loss using Infra Red Camera

Epogee Ltd offers a thermal imaging service using state-of-the-art colour thermal imaging technology. Our high-end camera boasts high sensitivity to infra red emissions as well as high definition quality colour photographs and video (click to see specification). This technique is ideal for carrying out a thermal heat loss survey of houses or other buildings. The thermal imager will be able to identify areas which have poor heat-loss characteristics, potentially allowing remedial action to be taken. Thermal imaging is also useful for identifying the location and source of damp within walls and ceilings. Thermal imagery has various other uses (click to view). The pictures below have all been captured by our thermal imaging camera. We offer thermal imaging surveys which cost £100 for a typical house (plus a mileage charge of 40p/mile). We can also provide thermal imaging services for a variety of other purposes - please see details below
Thermal Imaging chimney solar panel The vacuum tube solar panel on this house roof radiates almost no heat, so it shows up black. The chimney is hot due to the exhaust from a woodstove. You can also see heatloss above the windows (shown green) - this is due to heat transfer via a cast lintel which spans the cavity of the cavity wall.
Thermal Imaging Air Vent The double-glazed window units in this picture have heat loss around their edges - where the two glazing units are bridged by the edge-seal. There is also significant heat loss from the air vent to the right of the window.
Thermal Image Window Frame This double-glazed window is showing heatloss around a poor closure seal of one of the openning sections, which allows warmth to escape.
Thermal Imaging Roof Chimney Heat loss from these skylight windows is minimal due to thick double-glazing and low-E glass. The hot-spots on the walls are due to a floodlight (which is actually NOT lit) and the exhaust vent from a boiler (NOT running). You can also just about make out the heat from the LNB of the satellite dish between the windows. Again, the heatloss from the above-window solid lintel can clearly be seen.


Thermal Image Damp Door Frame This portacabin door and window lose an immense amount of heat. The flimsy door panels allow an easy escape-path for heat loss, as does the single glazed window. The door is a good fit inside the frame. What look like a gap is actually heat loss due to damp in the doorframe.
Thermal Image Roof Hot spot This house does not have a cavity wall, so the walls lose considerably more heat than the roof. To the left of the bush, you can see a hotspot in the wall, caused by the heat of a radiator. An adhesive reflector panel on the wall would be of benefit here.
Thermal Imaging Gutter leak This gutter has been leaking, and the trail of damp in the wall is easily picked up by the thermal imaging camera.
