SEKIsUi s-lec™

Solar Control FILM

Leave discomfort at the curb. SEKISUI S-LEC™ Solar Control Films with fine particle dispersion technologies enable comfortable and efficient vehicle designs for passengers.


S-LEC™ Solar Control Film technology is three-fold – blocks IR rays responsible for heat sensation, allows visible light rays for optical clarity, and allows transmission of frequencies necessary for cellular and sensor communication. Experience a comfortable, efficient, connected, and safe ride with our Solar Control PVB Technologies.


S-LEC™ Solar Control Film incorporates Sekisui’s fine particle dispersion technology which allows a variety of engineering functions to be evenly distributed within a PVB interlayer film resin. This technology significantly reduces the transmittance of UVA, UVB and infrared rays. The reduced UV exposure and heat on the skin protects the occupant and enhances their comfort.


S-LEC™ Solar Control Film quenches many of the sun’s mid-infrared rays between 1,500 and 2,100 nm. As demonstrated in the graph, the effectiveness of S-LEC™ Solar Control Film surpasses heat absorbing green glass.
