Product features

The acoustic interlayer film S-LEC™ Sound Acoustic Film is achieved using a 3-layer extrusion technology that mounts a (core) soundproof layer between existing (external) interlayer film layers. This improves the soundproofing performance while maintaining the same basic performance as regular interlayer film. Specifically, it improves acoustic permeation loss by 5dB compared to regular interlayer film in the 1,000 to 4,000Hz range, which is the easiest range for humans to hear. This frequency band is almost the same as the frequency of wind noise, which is the major source of noise when driving, and so can greatly cut out the wind noise. Further, it has excellent vibration suppression and effectively suppresses vibrations in the 100 to 500Hz range generated by the engine as well as cutting out the noise from the glass. In addition, adding soundproofing functions to the interlayer film can assure a fixed noise reduction without making the laminated glass layer thicker, thus also contributing to making the vehicle more lightweight and energy efficient.
