Unmeasurable amounts of IR escape from inside the walls of your home. The scanners only detect surface temperatures, and can only see through things with high transmission, like transparent glass, transparent plastics, air, etc. If you can see through it, so can the FLIR scanners, quite likely. Even water to a degree, but not very well. Water heavily absorbs IR, while allowing normal light to pass through it much easier.
There's actually a technique of using 'shallow pools of water' held in glass, of course, as IR barriers for plants grown under HID lights. It allows the lights to be used much closer without burning the plants, and also keeps the grow area much cooler.
