S-LEC™ Sound Acoustic film is based on patented three-layer-technology, composed of two outside layers of normal PVB for mechanical strength, plus a special core layer that delivers the sound reduction. We were world’s first with this technology and still are leader in sound acoustic interlayer films.
We work closely with glass manufacturers globally to enable a stunning design of glazing in buildings. Where possible, our technical engineers assist customers by finding solutions to increase production line efficiency.
S-LEC™ Interlayer film expands the possibilities of architectural glass by offering sound insulation, heat insulation, and design performance, while still providing the three basic performances of standard films: safety, security, and UV blocking.
S-LEC™ sound insulation’s success 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 in World Trade Center One
Together with our glazing partner we provided S-LEC™ acoustic interlayer Film for the laminated glass of World Trade Centre One. This enables extra safety and sound control, which is a remarkable stimulus for comfort in buildings situated in noisy environments.
Soundproof roof glazing
For the British Museum in London our clear and sound reducing S-LEC™ Sound Acoustic Film is applied in the glass roof. The final result is an astonishing combination of daylight, safety and quietness for optimal enjoyment of one of world's largest art collections.
Transparent sound control for noise barrier
21 kilometers glass noise barriers are placed at Outer-ring Parkstad (South-Limburg, The Netherlands), including SEKISUI's S-LEC™ Sound Acoustic Film
S-LEC™ Sound Acoustic Film brings peace and calmness into buildings by significantly reducing noises coming through glazing.
S-LEC™ Interlayer Film laminated glass prevents shattering and holds fragments in place to protect people from further injury.
S-LEC™ Interlayer Film laminated glass improves security protecting against burglary. It defends against forced entry, even when a hammer or glass cutter is involved.
