Window size is proportional to the intrusion of heat, and the increase in climate control needs. Therefore, windows which allow visible light to enter but block infrared light, are important to reduce the burden on air conditioning systems and save energy. S-LEC™ Solar Control Film filters out mid-infrared rays from sunlight, ultimately saving energy and improving comfort.


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.


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

Substantially cuts ultraviolet rays harmful to skin and products

S-LEC™ Solar Control Film has superior UV filtering performance to standard PVB film. As evident in the graph, the film substantially cuts the harmful ultraviolet rays that enter a room. S-LEC™ Solar Control Film protects people’s skin from sun damage and prevents discoloration of products displayed in shop windows. It is ideal for art gallery and museum displays to protect valuable assets.
