With the development of TROSIFOL SOUND CONTROL (TROSIFOL SC), a novel and special PVB acoustic film, TROSIFOL made a breakthrough in high-quality acoustic glazing. This product combines the outstanding sound insulation features of multiple glazing with all the advantages of a conventional TROSIFOL PVB film.
Even in monolithic laminated safety glass, TROSIFOL SOUND CONTROL reveals its outstanding sound insulation performance. Laminated safety glass consists of two plies of glass and one or more layers of polyvinyl butyral film, which are laminated at high pressures and temperatures to create a permanent bond between the plies. Laminated safety glass produced with TROSIFOL has outstanding security properties, as any glass fragments resulting from breakage remain stuck to the film and thus strongly reduce these fragments' capacity to cause injury. In terms of sound insulation values, insulating glass is up to 2 dB better than float glass of the same thickness.
Compared to float glass of the same thickness, an improvement of 5 dB in the sound insulation value is achieved in this example with TROSIFOL SOUND CONTROL. By optimizing the film composition, a further-improved film product is now available that again significantly and measurably improves the sound insulation performance of insulation glazing consisting of one or two laminated safety glass elements.
Laminated safety glass with TROSIFOL SOUND CONTROL complies with the requirements of the Construction Product List for laminated safety glass as well as the "Technical rules for linearly mounted glazing" of the German Institute of Construction Engineering. The product thus satisfies all the requirements of conventional laminated safety glass - even for overhead use and in glazing that prevents falls.
