Soundproofing
in buildings has become increasingly with the diversification of lifestyles
and increased concerns for privacy. In 1996, SEKISUI successfully developed
the S-LEC SAF (Sound Acoustic Film) sound control interlayer film that
dramatically increases sound insulation performance. This film has been
well received for architectural use in housing, offices, schools, and
commercial facilities.
S-LEC
SAF sound insulation interlayer film is achieved by the three-layer
extrusion technology that produces a film consisting of a sound insulation
layer (core layer) and two layers of standard interlayer film (external
layers) that sandwich the core layer. With this technology, the sound
insulation performance of the film is improved while it also maintains
the basic performance of standard 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.
