Expertise
We were world’s first with combining sound and solar control technology, and still are industry leader in multi-layer films. S-LEC™ Sound and Solar Film is fast becoming a cornerstone of contemporary architectural design.
We work closely with glass manufacturers globally to protect buildings from noise and heat, and enhance the level of comfort. Where possible, our technical engineers assist customers by finding solutions to increase production line efficiency.

Multi-layer and micro-particle technology
S-LEC™ Sound and Solar Film is a plastic layer inserted between sheets of PVB. Heat-insulating micro-particles are dispersed evenly within this multi layered structure. This enables the blocking of infrared (wavelength 1500-2100 nm) and ultraviolet rays, preventing skin irritation and extreme increase in temperature in buildings.
Especially during the summer, glazing equipped with S-LEC™ Sound and Solar Film can reduce up to 10 degrees compared to standard laminated glazing.
Electromagnetic Wave Transmission
Access to mobile communication is a necessity in buildings. Standard heat reflecting glass with metal coating reflects radio waves, which makes it difficult for mobile phones and radio’s to connect. S-LEC™ Sound and Solar Film allows major radio waves of all frequencies to transmit through glass, while blocking harmful rays.

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.

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.

European Research Centre at Brightlands Chemelot Campus
In 2017 SEKISUI S-Lec B.V. established its European Research Center (ERC) at Brightlands Chemelot Campus in Sittard-Geleen (the Netherlands). This landmarks a substantial boost for our technology evolution, product development, and global business in interlayer film for laminated glass, through the fusion of resources from SEKISUI and Brightlands.

Advantages
Noise reduction
S-LEC™ Sound and Solar film dramatically improves the sound insulating performance of glass. It suppresses outside noises and provides a serene environment, even in the the center of urban life.
Heat reduction
S-LEC™ Sound and Solar film prevents the increase of temperature in buildings, and keeps you comfortable regardless of the scorching heat outside.
Safety
S-LEC™ Interlayer Film laminated glass prevents shattering and holds fragments in place to protect people from further injury.
