Thermal imaging cannot be performed through glass because glass does not let infrared energy to pass through. Thermal imaging detects infrared radiation generated by any objects having a temperature greater than absolute zero. This radiation is undetectable to the naked eye, but a thermal imaging camera can detect it. 

Thermal imaging cameras can detect infrared radiation because they have a specific lens that detects infrared radiation. This lens may direct infrared energy onto a detector, where it is transformed into a picture. The resulting picture depicts the temperature of the items in the scene. 

When glass is present, however, the infrared light is obstructed, preventing the camera from detecting it. This is due to the fact that glass is not transparent to infrared light, which means it does not allow it to pass through. As a result, the thermal imaging camera will be unable to detect infrared light and will be unable to generate a picture. Thermal imaging via glass requires the use of a certain type of glass that is transparent to infrared light. IR-transparent glass is a form of glass that is particularly engineered to enable infrared radiation to flow through. This sort of glass is not generally accessible and is frequently pricey.
