BST-GL-001C Glass Thermal Insulation Nano Coating Solution
BST-GL-001C is a coating product capable of forming a spectrally selective reflective nano-quantum function on glass. It better blocks direct sunlight from entering the room, reducing the sultry feeling in summer and improving air-conditioning cooling efficiency. While providing high barrier rates against infrared and ultraviolet radiation, it ensures indoor lighting is not affected, significantly reducing indoor temperature by 8–12°C. In winter, it effectively reduces indoor heat loss through glass to the outside, reducing frequent heating operation of air conditioners, with advantages such as high-efficiency heat insulation, energy saving, warmth retention, and cold bridging prevention.

BST-GL-001C can be widely applied to thermal insulation, sun protection, and energy-saving retrofitting of existing building glass, such as various building glass curtain walls, glass doors and windows, and sunrooms. It can also serve as an ideal raw material for glass production/deep-processing enterprises to manufacture energy-saving single-pane glass and heat-insulating energy-saving insulating glass units.
