  3. If you feel a cold draft in the winter or a warm draft during the summer when sitting near your window, it is a clear sign of poor insulation. This problem can significantly increase your energy bill.
  4. If your window no longer remains open on its own, requiring you to prop it open, it is no longer in good condition.
