How to Soundproof a Door

When trying to make a home quieter, many people fail to consider soundproofing the door. The door is the largest opening in most rooms, and many interior doors are hollow, offering poor sound insulation. A sound proof door can make an enormous difference in noise levels, and is a do-it-yourself projects that most people can undertake and complete in a weekend. And best of all, soundproofing a door is a relatively inexpensive way to quiet a noisy home. Hollow doors fail to provide any insulation to muffle the sound, but sounds can even be increased by a hollow door. The interior space can carry sound. One of the first things to do in soundproofing a room is to replace a hollow door with a solid one. Doors can be purchased at many hardwood stores, and range from inexpensive to outrageous. Many people will find that they have the necessary skills to take the old door off the hinges and replace it with a solid core door.

Even with a solid core door, sound may be seeping through the doorway. Many doors have extra space between the door and the frame of the doorway. Weather-stripping can easily reduce the gaps in the door, and therefore reduce noise. Foam weather-stripping sound-reducing adhesive tape can be purchased at many hardware stores. It is typically sold by the roll, and usually one roll will be enough to soundproof one door. Begin at the edge of the door where the greatest gap is, and stick the foam soundproofing tape to the outer edge of the door. This will begin to close the gap between the door and the door frame.

Continue applying adhesive foam tape around the edges of the door, one side at a time. Assure that the tape is firmly put into place. As you progress, check to assure that the foam tape isn’t too thick for the gap between the door and the doorway. Usually the gaps on each side of the door aren’t equal, and may not need the same amount of foam tape applied. Where the gaps are large, apply a second layer of weather-stripping tape. Continue until the door is surrounded with the maximum amount of foam tape that will close the gaps and still allow for the door to easily open and shut. An added bonus of weather-stripping doors is that in some cases it can lower utility bills. Once the weather-stripping tape has been applied to a door, consider weather-stripping around the window to reduce the amount of noise that can come in or out. Not only will it help in the quest for noise reduction, it may also produce a savings in utility bills.
