Sound and Solar Film

Trends in contemporary architecture have led to the pursuit of more elaborate and larger glass surface designs. In the past, sunlight filling the room elevated the temperature to uncomfortable levels leading to the downfall of such designs. S-LEC™ Sound and Solar Film brings these designs to light without the noise and heat. By reducing sound and blocking heat rays (infrared rays), the film allows for bright yet cool, comfortable spaces. This eco-friendly design continues to provide relief from heat while economizing power save electricity in the summer and reducing air conditioning loads.


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.


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.


S-LEC™ Interlayer Film laminated glass prevents shattering and holds fragments in place to protect people from further injury.
