Sound and Solar Film

S-LEC™ Sound and Solar Film is a multi-functional interlayer film that shields the vehicle cabin from both heat and noise, enhancing passenger comfort levels for a more enjoyable driving experience. It simultaneously offers quietness, high fuel economy and a high level of safety in just one single sheet of film. A revolutionary solution.


We were world’s first with combining sound and solar control technology, and still are industry leader in automotive interlayer films. We work closely with leading glass manufacturers to protect your car from noise and heat, accelerating the level of comfort and eco-friendliness.

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 car temperature.

Especially during the summer, windshields equipped with
S-LEC™ Sound and Solar Film can reduce up to 10 degrees on steering wheels compared to those under standard windshields.

Electromagnetic Wave Transmission

Today mobile communication is a necessity while driving. Standard heat reflecting glass with metal coating reflects radio waves, which makes it difficult for mobile phones and Electronic Toll Collection (ETC) systems to receive waves. 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 brings peace and calmness to the interior of the car by significantly reducing noises coming through the glass from engine, tires, wind and rain.

Heat reduction

S-LEC™ Sound and Solar Film prevents the increase of car temperature and keeps you comfortable regardless of scorching heat outside.

Energy saving

The higher the temperature, the more airconditioning we use. This puts burden on the fuel or energy level of your vehicle. S-LEC™ Sound and Solar Film helps reducing fuel consumption and carbon dioxide emission by decreasing overuse of air conditioners.
