WebFor low emissivity coatings with high reflectivity, measurement is complicated, not very accurate or even impossible. Thermographic paints create high emissivity and homogeneous coatings on a hard to measure surface. Properties of thermographic paints defined in detail enable exact temperature measurement of the basic material. WebRoofs that are lighter in color or are reflective stay cooler than roofs that absorb sunlight. There are two ways to help cool a roof. First, a cool roof can reflect away sunlight, so it stays cooler. Such a roof is said to have a high solar reflectance. Second, a cool roof should also release or emit heat (infrared radiation) so it stays cool.
