Infrared (IR) thermography cannot literally see through walls, but it does observe temperature differences at the surface due to the presence and absence of embedded materials. Most commonly used to observe sub-surface moisture in roofs and walls, it can also be used to verify construction. Humidity problems in this French Renaissance Revival landmark converted to coop apartments suggested that insulation might be missing. These dramatic photos of the high-ceiling turrets taken by a SUPERSTRUCTURES thermographer evidence clear patterns of cooler (blue) rafters within warmer (yellow) insulation.
