Clearly Better Sound Quality

Bluetooth technology, voice-activated commands, onboard navigation systems, and sophisticated audio equipment make driving more enjoyable, yet they dial up the interior noise.   A new advanced Saflex® Q Series acoustic interlayer addresses this problem with precise acoustic control.   

Saflex Q Series is an advanced tri-layer polyvinyl butyral (PVB) interlayer that reduces noise level by 4.7 dB versus a standard windscreen and 5.9 dB compared to tempered side windows within the medium frequency range (1,000 – 5,000 Hz).

The Clarity is Real

Saflex Q Series advanced acoustic interlayers are especially effective within the frequency of human key voice recognition ranges (2,000 – 6,000 Hz), reducing sound transmission by 4.8 dB over this range. In other words, consumers can hear a difference, and that can speak volumes about brand experience and perceived quality.



Lightening the Load

In response to regulatory and consumer demand for greater fuel efficiency, automotive makers rely on every opportunity to reduce overall vehicle weight. Saflex Q Series helps reduce the negative trade-offs of typical weight reduction efforts by enabling improved acoustics, even in thinner glass configurations.

Saflex Q Series enables improved acoustics in when paired with thin glass.

This solves the weight issue… For a typical windscreen, the reduction of glass thickness from 2.1/2.1 mm to 2.1/1.6 mm would result in a weight savings of 1.7 kg (3.7 lbs) or 11%.  In a standard windshield, this would result in an acoustic performance loss of 0.6 dB over the full frequency range (200 – 10,000 Hz).  However, when Saflex Q interlayers are used in the thinner configuration, the weight reduction can be achieved while still improving acoustic dampening over the standard windshield by 1.2 dB over the same frequency range.  

The addition of acoustic front side glass (2.1/2.1 mm) can enable a further reduction of 1.1 kg (2.4 lbs) while improving sound transmission loss through the side windows by 3.3 dB versus 5 mm tempered glass.  Across all glazing positions, Saflex technology allows automakers to use thinner glass without sacrificing cabin comfort.

Lightweighting also helps auto manufacturers meet global environment regulations for lower CO2 emissions, including the Kyoto Protocol, the Economic Commission for Europe (ECE), and U.S. Corporate Average Fuel Economy (CAFE) standards.

Avoids Retooling Costs

Typical weight reduction solutions can require expensive retooling. Automotive glazing made with Saflex Q Series can be substituted into a vehicle’s existing glass with no need for expensive redesign, retooling, or research and development.
