TROSIFOL EXTRA PROTECT blocks UV Light

Invisible to the human eye, ultraviolet (UV) light is as vital as it is hazardous. While a certain degree of exposure is beneficial, too much of this part of the spectrum of natural sunlight is harmful.

 

Conventional window glass is impermeable to UV light below 320 nm. PVB films between glass plies filter out further UV light. TROSIFOL® EXTRA PROTECT is a new PVB film that blocks out incidental UV light in its entirety (>99%).
