These figures are measurement value of film-applied clear float glass (3mmt).
The optical measurements are conducted at normal incident angle (ISO 9050) and actual sun light incident angle may be oblique and angular optical properties are supposed to be different.

  • ※1It was placed vertically, and near infrared rays were irradiated at an incident angle of 60 degrees, near infrared rays which was reflected higher than the horizontal plane was measured. Multiplied by the weighting coefficients based on ISO 9050.
  • ※2It is an index of the shading performance of solar radiation.
  • ※3It is an index of heat insulation performance for a clear float glass applied with a window film.
