Abstract

Objectives: The aim of this study was to examine the potential for S-LEC™ Solar Control Film L, a heat insulating interlayer film for laminated glass developed by Sekisui Chemical Co., Ltd., to reduce the burning sensation caused by near infrared (NIR) radiation.

Methods: A crossover study was performed in 49 male and female subjects, using three different combinations of laminated glass with interlayer films. Subjects placed their right hand under each glass in an NIR irradiation device. The dorsal side of the right hand was irradiated with NIR for 30 s and the onset and degree of a burning sensation was measured.

Results: Laminated glass with S-LEC™ Solar Control Film L reduced the burning sensation caused by NIR and delayed the onset of the sensation, compared with the control glasses.

Conclusion: The use of S-LEC™ Solar Control Film L in the laminated glass of vehicles may improve passenger comfort and prevent skin disorders such as photoaging caused by prolonged exposure to NIR.

Keywords: burning sensation; heat insulation; interlayer film; near infrared.
