1) Transparency
HSF has higher than 80% visible light transmittance which is well satisfied with regulations of U.S. security standards for road trucking vehicles registered in 1951.
According to the standards requested visible light transmittance for automobile windows is above 70%.
2) Heat Shielding
HSF has 81% visible light transmittance and 75% IR ray blockage. When HSF is applied to the windows of automobiles and buildings, the temperature rise of inside space
is effectively suppressed and dramatically improved cooling efficiency of air-conditioners.
3) Durability
Metal particles used in HSF improve durability of films as compared to ordinary solar films and retain IR ray blocking property for good without deterioration.
4) UV Screening Effect
HSF also shields 99% of UV ray. Therefore, HSF prevents human skins and furniture from damage and decolorization by sun light.
