How to Check Your Windows Energy Performance

A warm room is not automatically a glass problem. Air can leak at the frame while the pane is fine. Sort those two before anyone talks about replacing the whole house.

What you'll learn

  • A smoke or incense check that shows moving air at the frame
  • Where a label on the glass lists the ratings, if one is still there
  • Heat through the pane versus a gap you can feel with your hand
  • Why comfort, not a promised bill, is the honest reason to replace glass here
