SEKIsUi s-lec™

Solar Control PVB

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


S-LEC™ Solar Control PVB 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 Interlayer incorporates Sekisui’s fine particle dispersion technology which allows a variety of engineering functions to be evenly distributed within a PVB interlayer 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 Interlayer 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 PVB surpasses heat absorbing green glass.
