New Automotive Glass Design

A man driving in a natural inside the car and a sophisticated new car glass design car

In recent automotive trends, many manufacturers and electric vehicle startups are embracing a seamless glass design that transforms the appearance of car glazing. Rather than segmented glass, this approach offers a continuous, extended glass surface from the windshield through the roof to the rear window. This design fosters a more open, sunlit cabin, enhancing the connection between occupants and their surroundings.

However, utilizing standard automotive glass in these expansive designs poses challenges, particularly with sunlight management. Traditionally, roof glass is tinted grey with low visible light transmittance, while windshields have high transparency, creating a visible line divider. This contrast can detract from the sleek, unified look of the glazing.

SEKISUI S-LEC offers S-LEC™ Wide Gradient Film, a specialized PVB interlayer for panoramic laminated glass, to address these design challenges. This film features a gradient that transitions from low-transmittance grey in the roof area to clear transparency in the driver and passenger’s line of sight. This gradation creates an aesthetic accent, enhancing the vehicle’s exterior appeal while ensuring a serene, private interior.

In addition to the aesthetic benefit, S-LEC™ Wide Gradient Film provides UV and glare control, which is essential for driver and passenger comfort.

Windshield

In addition to enhancing the design, S-LEC™ Wide Gradient Film protects the driver’s eyes from the sunlight entering the top of the windshield by adjusting the light transmittance.

S-LEC™ Wide Gradient Film has a lineup of multiple types of designs with different gradation widths and visible light transmittance of the colour portion. The appropriate combination of products can be selected according to the desired design. Customization of film design is also possible based on inquiry.

Rear Window

S-LEC™ Wide Gradient Film provides advanced design for the rear glass window. S-LEC™ Wide Gradient Film CB 7001-7018 has unique transitions from a visible light transmittance (Tvis) of 1%~ to a privacy colour with Tvis of 18%.

Continuous gradation is also possible using films combining different gradients from the windshield to the roof and rear glass. The gradation from front to back gives the car a futuristic image.

Achieving Harmony Across Glazing

Colour matching between the windshield and paranomic roof glass

Consistent colour grading is critical when multiple glazed areas are involved. SEKISUI S-LEC offers films with harmonized colour options that maintain a unified look across the windshield, panoramic roof, and rear window.

Customized designs are also available through the joint development of automotive glass. Please get in touch with us about the glass colour appearance and design you seek.

Design Creation

Once a design has been created for the car windows, it is crucial to visualize the design glass in the vehicle concept. Our VR tool supports visualizing the image of equipping a car with S-LEC™ Wide Gradient Film to see how it looks to adopt different gradient designs to the glazing.

Automotive Glass Design

The automotive exterior is one of the first things consumers see. Out of the exterior, almost 30% is covered by glass, and the market trend shows that this number is increasing.

Glass in the automotive industry becomes one of the very important items which affects the entire design. S-LEC™ PVB interlayer film for laminated glass provides a variety of colours and gradients which support harmonisation of the entire car exterior and interior design.

Sound Acoustic for laminated glass Sound Acoustic

S-LEC™ Sound Acoustic Film can block outside noise from the outside world, such as traffic, wind, and other disturbing sounds to tune out distractions for people to create a peaceful, quiet experience. 

You can combine acoustic quality with other functions or designs, such as solar protection or privacy colours, by incorporating soundproof film and other technologies into laminated glass.
