  • Consider using double paned windows instead of single pane which is less likely to vibrate when closed against each other.
  • Install thicker insulation around your door frame so that doors are more difficult for people outside to hear inside noise coming from within the house. -Hang heavy curtains over your slider so you can isolate yourself in a noisy environment without doing damage to walls, furniture, etc…
  • Make sure there are no cracks or something in the doors that might cause sound to escape.
  • If the doors are closing too quickly, then try putting a rubber mat or rug under them so they can land more softly and reduce noise.
  • You could also replace your sliding doors with french doors if you want an option that is less likely to create as much vibration when closed together.
