1. What is thermal insulation glass?
   Thermal insulationglass is a special-performance glass with excellent thermal insulation and heat preservation effects. It mainly achieves the thermal insulation function by reflecting and absorbing ultraviolet and infrared rays. Through optical microstructures, the glass is made into a selective mirror that reflects ultraviolet and infrared rays. As for absorption, components capable of absorbing light are added to the glass or the film, such as metal oxide nanoceramic films, so as to selectively absorb infrared rays while ensuring the light transmittance.
2. Classification of thermal insulation glass

• Laminated glass
  Application: residential buildings/sunrooms

Laminated glass is a type of glass product in which a special interlayer material is firmly bonded and placed between two or more layers of glass.This special material is usually a polyvinyl butyral (PVB) film. These film layers can not only enhance the safety of the glass but also effectively block the penetration of ultraviolet and infrared rays, thus achieving the thermal insulation effect.

• Laminated insulating glass
  Application: residential buildings/sunrooms/office buildings
  Laminated insulating glass is a high-performance insulating glass that combines the characteristics of laminated glass and insulating glass. Comprising two or more sheets of glass, this glass product features at least one layer of laminated glass. A PVB interlayer film is precisely sandwiched between the glass layers. Meanwhile, an insulating space is created between the glass panes. This space is conventionally filled with dehydrated air or an inert gas, such as argon, to ensure stability and prevent chemical reactions.

This well - designed structure bestows the glass with outstanding thermal insulation, soundproofing, and safety capabilities.

• Nano-coated thermal-insulating glass
  Application: sliding doors of the lobby anteroom/exterior wall glass of factory buildings

Nano-coated insulating glass represents an innovative variety of energy-efficient glass.On the premise of ensuring a high visible light transmittance, it can effectively block ultraviolet and infrared rays and achieve the thermal insulation effect. This kind of glass usually realizes its function by coating a layer of nano-transparent thermal insulation coating on the glass surface. This coating has special optical properties and can achieve a high blocking rate in the infrared and ultraviolet light regions while maintaining a high transmittance in the visible light region.

• Nano-coated insulating hollowglass
  Application: office buildings/residential buildings/sunrooms
  After synthesizing the nano-coated glass into insulating glass, it can combine the advantages of both, that is, it can not only control the direct solar radiation but also limit the convective and conductive heat transfer. Even if the insulating glass fails, it still has an energy-saving effect.
