How effective is tinted glass at blocking UV rays?

How effective is tinted glass at blocking UV rays? How well does it protect interior decoration materials (such as carpets, furniture, etc.) from fading and aging under long-term use? Will it affect the growth of indoor plants?

Tinted glass has a significant effect in blocking ultraviolet rays and can effectively reduce indoor ultraviolet radiation, thus protecting indoor decoration materials and furniture and extending their service life. It may also have a certain impact on the growth of indoor plants.

UV blocking effect
Colored glass can effectively block a certain proportion of ultraviolet rays (UV) by adding metal oxides or other additives during the manufacturing process. The specific blocking effect depends on the color and thickness of the glass. Generally speaking, dark tinted glass has stronger UV blocking ability than light tinted glass. Typical tinted glass blocks approximately 40% to 70% of UV rays.

Protective effect on interior decoration materials
Since tinted glass can significantly reduce the amount of ultraviolet light transmitted, its protective effect on interior decoration materials and furniture is obvious:

Reduce fading: UV rays are one of the main causes of fading in carpets, upholstery fabrics and wallpapers. Tinted glass can effectively reduce the time these materials are exposed to UV rays, thereby slowing the rate of fading.
Extended lifespan: By reducing UV damage to materials, tinted glass can extend the life of interior decoration materials and furniture, maintaining their beauty and functionality.
Effects on indoor plant growth
Ultraviolet light has limited impact on plant photosynthesis, but visible light (especially blue light and red light) is crucial to plant growth. The application of tinted glass may have the following effects on the growth of indoor plants:

Reduce light intensity: Tinted glass reduces the amount of visible light that passes through, resulting in lower indoor light intensity. This may affect the growth of some plants with higher light requirements.
Choose suitable plants: In an environment covered by tinted glass, you can choose plants with strong shade tolerance and low light requirements to adapt to lower light intensity.

Tinted glass has a remarkable effect in blocking ultraviolet rays, has a good protective effect on interior decoration materials and furniture, and can slow down their fading and aging. However, when it comes to growing indoor plants, tinted glass can present challenges, requiring plant species to be chosen on a case-by-case basis, and possibly requiring additional artificial light sources to supplement the lighting.

Tinted glass is an efficient building material that can play an important role in improving building energy efficiency, aesthetics, and protecting indoor items. However, its overall impact on the indoor environment needs to be considered during design and application.
