SEkisUi s-lec™

Sound & Solar PVB

Consumers demand safety, beauty, and comfort without concession, and designers are challenged to deliver. S-LEC™ Sound & Solar Interlayer delivers, with dual sound and solar heat shielding capability.


The optimal product designed for occupant comfort, this enhanced technology merges the performance features of sound and solar products into one. Keeping the interior quiet and cool – the ultimate combination of comfort that glazing can offer.


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.


While standard PVB interlayer filters out more than 99% of ultraviolet rays, most of the infrared rays penetrate the film. S-LEC™ Sound and Solar PVB 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.
