Sound Acoustic Film

SEKISUI S-LEC™ Acoustic Film greatly reduces the sound of the wind and the car-engine, as well as reducing traffic noise and other external sounds. It offers 40% more acoustic protection than standard interlayer film in laminated glass. Noise is a huge pollutant when driving, which makes increased sound reduction a valuable addition to any car.


We were world’s first with this technology and still are industry leader in sound acoustic automotive interlayer films, enhancing comfort in the majority of cars around the globe.

We work closely with leading glass manufacturers. Where possible, our technical engineers assist customers by finding solutions to increase production line efficiency.

Multi-layer Technology

The sound-insulation succes of SEKISUI S-LEC™ Acoustic Film lies in a three-layer extrusion technology: A soundproof layer (core layer) is placed between two conventional interlayer films (outside layers). This method significantly improves sound insulation performance, while maintaining the same basic benefits of S-LEC™ Clear Film (Standard Interlayer).

Laminated glass with S-LEC™ sound insulation interlayer film works best at dampening the 1,000 to 4,000Hz sounds humans hear most. This opens possibilities for more quiet, creative spaces. S-LEC™ Sound Acoustic Film, with superior dampening performance, reduces glass vibration and blocks outside noise.


Noise Reduction

S-LEC™ Sound Acoustic Film brings peace and calmness to the interior of the car by significantly reducing noises coming through glass from engine, tires, wind and rain.


S-LEC™ PVB film with high impenetrability, will protect the glass from shattering, saving visibility and preventing shattering to minimize the likelihood of occupant injury.


Sunbeams contain ultraviolet rays which can cause sunburns and color fade for car interior. S-LEC™ PVB Film filters more than 99% of these harmful ultraviolet rays.
