All images are from a Testo 875-2 Thermal Imager and were taken at night. The sky is at the lowest effective temperature as indicated on the scale adjacent to each image. The relative temperatures of windows, walls and other objects indicate the most significant sources of heat loss or gain.
Above image illustrates a well insulated roof with few infiltration channels showing up as heat loss - good window heat retention
Above image indicates the dramatic heat loss through a wall structure dedicated to large expanses of windows
Heat retention in protected areas show up as warmer than surrounding areas
Roof and garage show areas of infiltration problems that may need some consideration
Insulation oversight of garage wall (red) with indications of wall infiltration on other walls but good window heat retention
Roofline heat loss indicating possible ventilation into attic cavity and windows showing significant heat retention
Significant heat loss around window seals and dramatic loss at junction of an EIFS (insulated) wall system and an uninsulated concrete crawlspace foundation
Illustrates different rates of heat absorption and subsequent heat exhaustion between different material densities as well as color variations - Note: Street vs. Sidewalk
Note warmer internal water temperature in water tower at the image background
Reflected image of cameraman indicates both camera sensitivity and extraordinary radiant reflectance capability of superb quality window with heat mirror technology
Very good roof insulation with one wall showing less insulating value than other parts of home - possibly poorly installed fiberglass bat insulation
Body image showing warmer and colder regions of the body - Note that the extremities are cooler
Wall behind rock facade is found to have poor insulation which causes conduction of heat from the house
