Double glazing reduces conduction through a window mainly because of

  • A.the reduced solar transmittance of two panes
  • B.the improved airtightness of the frame
  • C.the resistance of the gas layer between the panes
  • D.the extra thickness of the glass itself

Answer: C

Glass itself is a poor insulator whatever its thickness; the still gas layer between the panes is what provides the resistance, and argon does better than air. It reduces the conduction and does comparatively little about the solar gain.
