UV Blocking
Protect people and objects

Ultraviolet rays in sunlight

We receive a great amount of sunlight in our daily lives. On the other hand, overexposure to sunlight poses the risk of skin aging (photoaging) and skin cancer due to the effects of ultraviolet rays contained in sunlight.

Ultraviolet rays can be divided into three types according to their wavelengths: UV-A, UV-B, and UV-C. UV-C (200-280nm), the most harmful type of ultraviolet radiation, is mostly absorbed by the ozone layer and does not reach the surface of the earth; UV-B (280-315nm) reaches only the outer layer of the skin, but can cause dermatitis, freckles, and dry skin; UV-A (314-400nm) is hardly absorbed by the ozone layer and reaches the earth’s surface even on cloudy days. UV-A can penetrate into deeper layers of the skin (dermis) and can cause long-term skin damage to the human body. In addition, UV-A light can damage and age objects.

S-LEC™ Premium Blocking Film UA01

Laminated glass with a standard PVB interlayer film does not cut off all UV-A, allowing it to enter the interior of the vehicle.

S-LEC™ Premium UV Blocking Film UA01 has the world’s highest level of UV-A blocking performance as an interlayer film for automotive laminated glass, blocking more than 99.9%*1 of UV-A, preventing light radiation from entering the interior of vehicles.

*1 ISO13837 standard, please contact us for detailed data.

Achieving health and comfort

UV-A can penetrate deeper layers of the skin (dermis) and can cause long-term skin damage.

Laminated glass using our S-LEC™ Premium UV Blocking Film UA01 offers exceptional UV-A blocking performance, reducing UV-A transmission to less than 0.1% compared to standard laminated glass. In combination with the S-LEC™ Solar Control Film, it becomes possible to cut infrared rays in addition to ultraviolet rays to reduce the interior of your vehicle from heating up, resulting in a more comfortable and health-benefiting car interior.

At SEKISUI S-LEC we are committed to creating new valuable solutions through PVB interlayer films for laminated glass to contribute to the developments in the ever-growing automotive and architectural industry.


Protection of people

Since UV-A reaches deeper into the skin, prolonged and large amounts of exposure can damage the skin, causing inflammation and premature aging.

S-LEC™ Premium UV Blocking Film UA01, when installed on car windshields and side windows, blocks UV- from entering the car and protects the skin of those who need UV protection from photoaging and prevents premature aging such as spots and sagging skin.

Protection of objects

When exposed to UV rays from outside, the vehicle’s interior components, such as the car seats and dashboard, are subject to degradation and discoloration caused by sun bleaching. This spoils their value. Laminated glass that uses S-LEC™ Premium UV Blocking Film UA01 substantially cuts out the UV-A rays that enter the vehicle, thus preserving its interior.

Combinations with UV Blocking

We offer the following combinations of multiple functions into one film:

  • Sound Acoustic
  • Solar Control
Sound Acoustic Sound Acoustic

S-LEC™ Sound Acoustic Film can be used to block outside noise from the outside world such as traffic, wind, and other disturbing sounds to tune out distractions for the driver and passengers to create a peaceful, quiet driving experience.  S-LEC™ Sound Acoustic Film can also help you get the most out of the music that you play in the vehicle.

Solar Control Solar Control

Keeps you cool and blocks infrared rays without compromising clear vision.

Laminated glass with S-LEC™ Solar Control Film blocks infrared and UV rays but allows visible light rays for optical clarity without blocking the electromagnetic transmissions necessary for mobile phone and sensor communication. Solar absorbing glass realized by S-LEC™ Solar Control Film protects the driver and passengers because the cabin stays cooler and your skin does not burn.
