EXTRA CLEAR LAMINATED GLASS FOR THE MAXIMUM PROTECTION AGAINST UV RAYS

In residential or commercial applications, laminated glass with EVA STRATO® EXTRA CHIARO is the best solution to an underestimated problem: the transmission of UV rays.

What are UV rays?

They are a form of radiation invisible to the human eye. They represent the portion of the electromagnetic spectrum located between X-rays and visible light and they have a wavelength between 100 – 400 nm.

The UV energy of the sun is divided into three categories:

  • UV(C) has the shortest wavelenght (100-280 nm) and is the most harmful but fortunately it is mostly blocked by the earth’s atmosphere
  • UV(B) is the next shortest wavelenght (280-315 nm) and it is mostly blocked by traditional float glass that is used to make Windows
  • UV(A) has a wavelenght between 315 – 400 nm and it is tipically given most attention in glazing systems. This radiation occurs all year round no matter what season it is and they represent about 95% of the ultraviolet radiation that reaches the earth’s surface. They are harmful to people but they are also the main cause of discoloration of furniture and furnishings or degradation of goods on display.

At home or in the office you could still be exposed to UV rays, in fact the glass surfaces allow the passage of light, heat and sunlight.

To minimize the risk caused by UV exposure, we suggest to use glass laminated with EVA film STRATO® EXTRA CHIARO. The insertion of this interlayer between two panes of glass guarantees the maximum protection from UV rays, blocking over 99% of their transmission while maintaining high light transmission (> 90%). It is also highly performing in terms of resistance and safety.
