In these years, constructors and car makers
have been designing their products paying mush attention to the efficiency
of sound insulation, because residential noise and vehicle's sound
control performance have come to light. SEKISUI succeeded to develop
a high-performance sound control interlayer film, named S-LEC Acoustic
Film that also has the maximized human-safety performance of normal
interlayer films. Since 1996, our Acoustic Film has been well received
in the markets for architecture and automotive.
*In some areas, we may have sales limitation. For details, please

| The sound control performance
of our Acoustic Film is achieved by the three-layer extrusion technology
that produces a film consists of a sound control layer (core layer)
and two layers of normal interlayer film (external layers) that sandwich
the core layer. With this technology, the sound control performance
of this film is improved while it also maintains the other performance
of normal interlayer films. |

 |
| In human's most audible sound
range from 1000 to 4000Hz, our Acoustic Film achieves 5dB of sound
control effect that is higher than those of other normal interlayer
films. |

*Most distinctively high sound control
performance in human's most audible sound range from 1000 to 4000Hz
*5dB of sound control effect at the maximum compared with other normal
laminated glass |

of 5dB difference in actual environment |
