WebCan thermal imaging see through metal? Metal can be a tricky material in the thermography world. Shiny metal—any metal object that is smooth or polished—will reflect infrared radiation, acting as an infrared mirror just like glass. This can cause difficulties for anyone trying to monitor pipes or machinery for overheating parts.

WebReflectiveness definitely determines how much IR is emitted and absorbed: a mirror reflects light off, turning it away rather than absorbing it. The color also affects infrared radiation. A white shirt will be cooler in direct sunlight than a black one. Temperature does not affect the absorption but rather the emission of IR.
