Infrared Picture

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.




TestoPic2

Above image illustrates a well insulated roof with few infiltration channels showing up as heat loss - good window heat retention



TestoPic3

Above image indicates the dramatic heat loss through a wall structure dedicated to large expanses of windows



TestoPic4

Heat retention in protected areas show up as warmer than surrounding areas



TestoPic5

Roof and garage show areas of infiltration problems that may need some consideration



TestoPic6

Insulation oversight of garage wall (red) with indications of wall infiltration on other walls but good window heat retention



TestoPic7

Roofline heat loss indicating possible ventilation into attic cavity and windows showing significant heat retention



TestoPic8

Significant heat loss around window seals and dramatic loss at junction of an EIFS (insulated) wall system and an uninsulated concrete crawlspace foundation



TestoPic9

Illustrates different rates of heat absorption and subsequent heat exhaustion between different material densities as well as color variations - Note: Street vs. Sidewalk



TestoPic10

Note warmer internal water temperature in water tower at the image background



TestoPic11

Reflected image of cameraman indicates both camera sensitivity and extraordinary radiant reflectance capability of superb quality window with heat mirror technology



TestoPic12

Very good roof insulation with one wall showing less insulating value than other parts of home - possibly poorly installed fiberglass bat insulation



TestoPic13

Body image showing warmer and colder regions of the body - Note that the extremities are cooler



Front Facade

Wall behind rock facade is found to have poor insulation which causes conduction of heat from the house
