Coated glass is indeed divided into two types: high transmittance and low transmittance. Below is a specific introduction and distinction between these two types of coated glass.
High transmittance coated glass
Characteristics:
It has a high light transmittance, usually over 70%, with some even reaching around 88%.
The color is lighter, with good lighting effects and strong transparency.
The ability to reflect far-infrared thermal radiation in light is relatively weak, but the insulation performance is still good.
Application scenarios:
Suitable for cold northern regions, effectively maintaining indoor warmth.
Suitable for buildings that require high transparency and lighting effects, such as large public buildings and commercial complexes.
2. Low transmittance coated glass
Characteristics:
It has a lower light transmittance, usually below 50%.
It has good heat insulation effects, effectively blocking solar radiation and heat transfer.
The ability to reflect far-infrared thermal radiation in light is strong, suitable for summer shading and heat insulation.
Application scenarios:
Suitable for buildings in tropical or subtropical regions, as well as situations that require shading and heat insulation.
Suitable for places like museums and libraries that have lower light requirements and need to control temperature.
3. Distinction methods
Light transmittance:
The most intuitive distinction is the difference in light transmittance. High transmittance coated glass has a significantly higher transmittance than low transmittance coated glass.
Color and visual effects:
High transmittance coated glass has a lighter color and a strong sense of visual transparency; while low transmittance coated glass has a relatively darker color, providing a more stable visual effect.
Function and application:
Distinguished based on usage scenarios and functional needs. For example, northern cold regions tend to use high transmittance coated glass to maintain indoor warmth; while tropical or subtropical regions tend to use low transmittance coated glass for shading and heat insulation.
Testing and identification:
You can use a lighter or flashlight as a light source close to the glass for observation. High transmittance coated glass will show a lighter blue shadow in the light source's projection; while low transmittance coated glass may show a reddish shadow. However, this method is only a preliminary identification means, and specific verification should be combined with professional testing tools.
In summary, there are significant differences between high transmittance and low transmittance types of coated glass in terms of light transmittance, color and visual effects, function and application, as well as testing and identification. When choosing coated glass, comprehensive consideration should be given based on specific usage scenarios and functional needs.
