How to Soundproof Windows & Interior Shutters

Updated February 21, 2017

Whether you have a loud neighbour or a busy street outside your window, or if you like to play an instrument loudly, you may want to soundproof your windows. Soundproofing the interior shutters on the window will allow you to soundproof without getting rid of the shutters. You can easily make a slight adjustment to your shutters that will not only drastically reduce the noise flow from your room and outside, but will also add a slight decorative flair to you windows.

Remove the shutters from the window frame with a screwdriver and lay them on a table.

Cut a piece of soundproofing mat to the shape of the shutters, using a utility knife.

Cover the mat with material that matches the room. Use a staple gun to secure the material around one side and all of the edges of the mat. The back of the mat needn’t be completely covered.

Attach the covered mat to the inside of the shutters that are laying flat. Line the mat up on the shutters so all of the corners are flush.

Place a metal washer on each corner of the shutters. You should have four washers for each shutter. Drill a screw through the washer, covered mat and the shutters with a power drill. This will attach the mat to the shutters.

Apply a self-adhesive weather stripping around the outside edge of the shutter. This is just pressed onto the edge and allowed to set for a few minutes.

Reattach the shutters to the window frame and keep closed for soundproofing.


Add curtains, carpets and other soft furnishings to help absorb sound and further soundproof your room.


The soundproofing will block out light from coming in through the shutters.
