1. Heat reflective glass
Heat reflective glass is coated with a metal film and some interference layers on the surface, allowing the glass product to reflect and achieve shading, while also having rich colors. Heat reflective glass has strong reflection of both visible light and long waves, and its function is to restrict the entry of the sun into the room.
Disadvantages: The insulation properties of heat reflective glass are almost the same as transparent glass, so it is not suitable for cold areas with large temperature differences indoors; But in areas with strong sunlight. Reflective glass not only reflects the sun, but also limits the entry of visible light, which can have adverse effects on indoor lighting. In addition, high reflectivity can lead to light pollution, while low reflectivity cannot achieve the desired level
It is the use of vacuum deposition to form a layer of Low-E coating on the surface of glass. The function of Low-E coating is first to reflect far-infrared and the heat transfer coefficient of glass; Secondly, there is a selective shading coefficient in reflecting the sun; Meanwhile, compared to heat reflective glass, glass does not impose too many restrictions on the penetration of visible light.
Disadvantage: Due to the poor strength of the membrane layer, it is generally made into insulating glass and not used separately.
