Thermal imaging cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 9,000-14,000 nanometers or 9-14 µm) and produce images of that radiation, called thermograms. (Wikipedia). The use of thermal imaging in the building industry is generally about evaluating and addressing energy issues in homes and other buildings. As an experienced Wisconsin thermal imaging contractor, North Twin Builders has served clients in Eagle River, Land O Lakes, St. Germain, and Three Lakes, as well as select areas in Upper Michigan. North Twin Builders is a level one thermographer (SP), which required 32 hours of thermal imaging training.
