Temperature-reducing glass is an optical material with special thermal regulation properties, designed to reduce and control temperature increases, particularly in high-temperature environments or situations where low temperatures need to be maintained. Unlike temperature-increasing glass, temperature-reducing glass helps lower the impact of light or heat sources by reflecting, absorbing, or insulating against thermal radiation, thus maintaining a lower temperature. This type of glass is widely used in architecture, industry, electronic equipment protection, automotive glass, and solar energy technologies, providing effective thermal management and improved energy efficiency.
