What Is a Hot Mirror?
A hot mirror is a mirror coated with a coating that transmits visible light and reflects infrared light, keeping indoor spaces warm.
It achieves this through a coating layer that transmits visible light from sunlight while reflecting only infrared light. This prevents indoor heat from escaping to the outside, thus maintaining room temperature. Notably, it helps prevent heat loss and condensation indoors while also contributing to privacy protection.
Hot mirrors are widely used in residences, automobiles, and other applications. In homes, they can be applied to window glass to prevent heat loss indoors and reduce condensation. In automobiles, they are used on car windows to improve heating efficiency in winter and reduce temperature rise in summer. Additionally, in greenhouses, they help maintain the heat necessary for plant growth and contribute to reducing heating costs in winter.
