The emission of infrared light, which is invisible to the human eye, from a warm body is called thermal radiation. The thermal radiation that is emitted transports energy so that the radiating body constantly loses heat, which has to be replenished to maintain its temperature. This heat loss consequently leads to rising energy costs.
A reflective layer in the infrared range greatly reduces the infrared transmission. The coating thus protects infrared-sensitive substrates and reflects the thermal radiation back into the body, therefore significantly improving the energy efficiency.
- Thermal protection
- Improvement of energy efficiency
- Infrared transmission greatly reduced
