A sound solution advanced acoustic glazing technology High performance interlayers for laminated glass

Exterior applications Designing for sound reduction Modern building designs emphasize liberal use of glass. Meanwhile, building owners and occupants demand comfort—including reduced ambient noise. However, sound transmission is greatest through glazing made with ordinary window glass. This is especially a challenge for designers and engineers developing urban projects along highways, railroads, and airports. The answer is not less glass but new glazing materials, such as Saflex® Acoustic interlayers with proven sound-dampening performance. Isolating interior building spaces from exterior...

Interior applications With the growing trend of open architectural environments and increased use of glass for • usiness offices, boardrooms, meeting B rooms, and cubicles interior walls, unwanted sound is on the rise. • Hotel and restaurant spaces Unfortunately, ordinary glass is a poor acoustic • Medical care centers and health clinics barrier. Interior sound pollution can make it • School classrooms and lecture halls more difficult to concentrate, to speak on the phone, or to keep information private and confidential. Many application opportunities exist where Saflex can provide...

Reduces perceived loudness by up to 50% While laminated glass with standard PVB interlayers provides noise reduction capabilities compared to ordinary glass, the new Saflex® Acoustic PVB is a superior solution for architects specifying glazing systems requiring even higher levels of acoustic comfort. Saflex Acoustic is an advanced, three-layer system designed to decouple and disseminate sound waves for superior sound dampening performance. This patented system targets sounds in the 1,000-3,000 Hz range, which is the most sensitive range of human hearing. A recent study by the Institute of...

Sound transmission loss Acoustic data for select configurations 50 Sound transmission loss R (dB) — Saflex® Acoustic interlayer - Saflex® Clear interlayer * Sound transmission loss of laminated glass with SafleX® Acoustic interlayer and SafleX® Clear interlayer Configuration = 44.2 The ability to reduce noise as perceived by the human ear can be measured. This measurement involves sending specific frequencies of sound through a material, in this case, laminated glass with Saflex® Acoustic interlayer, and remeasuring what comes "through" the glass to determine what gets "filtered" out. The...
