Leaves the heat behind

S-LEC™ Solar Control Film

S-LEC™ Solar Control Film blocks infrared rays and UV (ultraviolet) entering a vehicle, allows visible light rays for optical clarity, and allows transmission of frequencies necessary for cellular and sensor communication. Thus, S-LEC™ Solar Control Film protects the cabin of vehicles and your skin from the heat.

Experience a comfortable, efficient, connected and safe environment.

Application for Automotive Glasses

By combining with various solutions, S-LEC™ Solar Control Film can be applied not only to windshield but also to all automotive glasses such as side windows, roof glazing and rear windows to improve solar performance in the entire vehicle.

Application for Electric Vehicles

In exterior design of electric vehicles (EV), the windshield, roof glass and rear window are increasingly being designed to look like one large integrated glass panel. Due to the increase of the glass size more sunlight can enter the interior.
By improving solar control functionality of the glass, electric vehicles can be kept cool and the driving range can be improved.

Solar Grades

The required solar control performance varies depending on the vehicle concept or regional market needs.
S-LEC™ Solar Control Film has three types of solar grades, L, AN02, AN01 and custom options to suit a range of requirements or glass combinations. S-LEC™ Solar Control Film provides a wide range of options for automotive and glass engineers. SEKISUI S-LEC proposes an optimal solar control performance to any vehicles from small vehicles to luxury ones.

EM Transmittance

S-LEC™ films allow most radio frequency bands to pass freely, unlike traditional heat reflective glass with a metallic coating. S-LEC™ films enable drivers and passengers to remain connected while on the go. These technologies also allow the convenient use of electronic toll devices without any interference.

Energy Saving with EV

S-LEC™ Solar Control Film can reduce the amount of energy consumed by air conditioning in electric vehicles. Through vehicle testing, SEKISUI S-LEC has confirmed up to 20% saved.

Thermal Comfort
S-LEC™ Solar Control Film prevents the increase of a car’s interior temperature and keeps you comfortable regardless of the heat outside. SEKISUI S-LEC research showed that 94% of people prefer the thermal comfort of the SEKISUI S-LEC solution compared to normal glazing.
Solar Innovation

S-LEC™ Solar Control Film has three types of solar grades and custom options. These can be combined with any glass type to realize the best solar performance fully.

Solar Control Webinar

Learn all about the benefits.

S-LEC™ Solar Control Film blocks the sunlight entering into a vehicle, providing comfort and reducing the energy consumption of air conditioner, contributing to extending driving range of EV.

In this webinar, we offer a wide variety of solutions provided by S-LEC™ Solar Control Film used in automotive laminated glasses all over the world.

Combinations with Solar

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

  • Panoramic Rooflite
  • Design
  • Head-Up Display
  • Sound
Panoramic Rooflite Panoramic Rooflite

Especially for electric vehicles, roof glass is increasing in size which makes it more important to control the amount of sunlight entering into a vehicle. S-LEC™ Solar Control Film can be combined with Colour. SEKISUI S-LEC offers multiple options for Tvis (Visible Light Transmittance) to optimize various glass combinations according to a vehicle’s requirements.

Head-up Display Head-up Display

Head-up Display(HUD) is rapidly becoming a popular driving interface in cars ranging from luxury to standard models. Wedge shaped S-LEC™ Solar Control Film enables real times images to be projected clearly by controlling light refraction.

When laminated with a metallic coating film, projected images may appear more blurry because of the reflection of light by the coating layer. S-LEC™ Solar Control Film, in which IR cut fine particles are dispersed, does not cause such a phenomenon and realizes both of clear HUD images and enhanced solar performance.

Design Design

S-LEC™ films are currently available in a wide range of standard colours and custom colour options with multiple Tvis (Visible Light Transmittance) to optimize various glass combinations according to a vehicle’s concept.

S-LEC™ Solar Control Film can also be combined with a wide gradient colour that transitions from 2% to >70% Tvis(Visible Light Transmittance). By adapting on windshield or rear window, it creates a feeling of openness and a beauty by smooth gradation, providing an advanced design for automotive glass.

Sound Sound

By incorporating sound acoustic function into S-LEC™ Solar Control Film, the transmission of exterior noises is reduced for the highest level of luxury and comfort on the market.
