They carefully analyze the glass and air-space temperatures of windows with solar film applied before recommending any film for multiple-pane windows.

They then compare these temperatures to temperatures of tinted windows from the glass or window manufacturer, so-called manufacturer's original equipment or OEM. These films do not cause an air-space temperature increase any greater than OEM tinted glass and, therefore, are safe to apply in most cases.
