In the world today, comfort no longer has to be sacrificed for safety. Consumers demand both without concession, and designers are challenged to deliver. S-LEC™ Sound and Solar Film has simultaneous sound and solar heat shielding abilities, in addition to the intrinsic features of safety, security and shielding that you expect from laminated PVB glass. This technology enables designers to meet customer expectations of form and enhanced function, for a comfortable indoor environment.


S-LEC™ Sound and Solar Film is constructed from a patented three-layer extrusion technology. The outer layers provide mechanical strength and enables adhesion to the glass. The inner layer absorbs unwanted sound frequencies. Sekisui’s solar control particles are then evenly distributed throughout the multi-layer structure. This combination of technologies enables sound dampening and heat control in one comprehensive product.

Glass shields heat, filters out mid-infrared rays to mitigate heat source

-Lec™ Sound & Solar Film for architectural use cuts UV rays and mid-IR rays, the primary cause of burning sensation on skin.

While standard PVB interlayer film filters out more than 99% of ultraviolet rays, most of the infrared rays penetrate the film. S-LEC™ Sound and Solar Film for architectural use substantially cuts ultraviolet rays as well as mid-infrared rays from 1,300 to 2,100 nm - the primary cause of the burning sensation on the skin.

Cut sound energy down to a third

As evident in the graph, S-LEC™ Sound and Solar Film effectively controls low frequency vibration energy from the engine and reduces high-frequency wind noise. These figures demonstrate that audible noise is reduced to a third of its original volume.
