How to Choose a Soundproof Interior Door

When shopping for a soundproof interior door, choose one of solid construction with good sound-deadening properties.

For an even greater level of soundproofing, consider a core foam-filled door — this will add further insulation and dampen more sound.

Various door seals are available that can help provide additional protection from outside noise.

Which Types of interior doors are more Soundproofed?

When choosing a soundproof interior door, it’s important to consider the type of door you’re looking for.

  1. Hinged doors are the most common and can be made from solid wood, aluminum, or steel. Solid wood doors are usually the most effective at blocking noise due to their density and mass. Aluminum and steel doors are both very durable and provide good sound insulation. Still, they will also be heavier than wood.
  2. Sliding, bi-fold, and pocket doors are not as effective at blocking sound, so these types are not recommended if you’re looking for a soundproof door.
  3. In addition to the type of door, you should also consider the thickness of the material. The thicker the material, the better it will be at blocking sound.
  4. Finally, look for doors with additional soundproofing features, such as rubber seals and weatherstripping, to reduce noise further.

Installing a Soundproof Interior Door

Once you’ve picked the right door for your needs, you want to install it carefully and properly.

  1. Start by leveling the doorway and framing it according to local building codes.
  2. Pay attention to the spacing around the edges of the frame — some materials need slightly more room than others, so double-check your measurements during installation.
  3. Once in place, device how best to seal any gaps or crevices between components.
  4. You can use weather stripping at the joints or caulk at window sills — as long as the air can’t enter, you’ll keep out outside noise.
  5. Finally, remember to use additional soundproof materials if needed.

Heavy curtains, double-pane windows, and acoustic panels can all help make your soundproof interior door even more effective.

How to Soundproof Interior Door (7 Options)

We have seen that different types of Doors have different levels of sound control. To further improve the soundproofing capabilities of a Door, there are some additional steps you can take:

#1. Apply weatherstrip

Weatherstripping on your door frame can help seal the gaps between the door and frame, preventing noise from entering or leaving the room.

Use a high-quality material when installing weatherstripping to improve the overall soundproofing performance.

The weatherstripping will help with soundproofing.

  1. To install it correctly, you need to measure the dimensions of the doorframe and purchase an appropriate-sized weatherstrip.
  2. Peel off the protective adhesive cover from the back of the weatherstrip and press it along the inside edge of the doorframe.
  3. Make sure to press firmly so that the seal is secure.

#2. Add acoustic insulation

Consider adding acoustic insulation like foam or fiberglass panels or blankets around your doorway for an even more effective soundproof door option.

Acoustic insulation helps absorb any sound that may pass through the gaps, making your interior room more secure from outside noise.

Acoustic insulation works by absorbing sound waves and trapping the energy between layers of material, preventing sound from traveling through the air and entering a room.

It also helps reduce noise reverberations inside the room, creating a quieter environment.

Acoustic insulation is particularly effective for blocking out relatively low-frequency noises, such as those caused by traffic or air conditioners.

#3. Install soundproof curtains

Soundproof curtains are a great way to add additional layers of protection to reduce noise pollution in your home or office space.

These heavy-duty insulating curtains can be used independently or with acoustic insulation panels or blankets to maximize soundproofing performance.

Soundproof curtains aid in soundproofing interior doors by providing an additional layer of insulation to absorb noise. When hung around a door, the thick material helps to block sound waves from entering the room.

Additionally, soundproof curtains act as a noise barrier between rooms, preventing loud conversations or other noises from spreading too far.

#4. Add surface treatments

Surface treatments such as mass-loaded vinyl (MLV) can also reduce noise if added to your door.

MLV is a heavy material loaded with lead particles providing an additional layer of soundproofing material in your doorway.

How do surface treatments for soundproof interior doors?

  1. Measure the dimensions of the door and purchase enough MLV to cover it.
  2. Cut the MLV to properly fit your door, allowing for a few inches of overlap on all sides.
  3. Install the MLV panels by starting at the top and working your way down. Secure each panel with adhesive or nails, depending on its thickness.
  4. Apply weather stripping to the exterior perimeter of your door frame to seal any gaps caused by fitting around all sides of the door frame, including any corners or crevices that may have been missed with your MLV installation.

#5. Replace With a Solid-core Door

Solid core doors are made from dense materials like wood, fiberglass, and metal, which help reduce sound penetration through the gaps. It is an ideal solution since the heavier weight of the material helps dampen sound transmission by absorbing and reducing vibrations that travel through it.

Solid core doors are typically constructed with sound-deadening material such as foam or fiberglass insulation sandwiched between two layers of wood or metal. It helps to absorb and dampen sound waves, preventing them from traveling through the door.

Additionally, weather stripping can be added around the door frame to reduce sound transmission further.

#6. Add A Door Gasket

Door gaskets are a great way to seal air leaks around your door and prevent sounds from vibrating through the gaps.

These foam seals come in various shapes and sizes and are essential for soundproofing any room.

These steps can help create a more soundproof door and reduce the amount of noise in or out of the room it’s installed in. In addition, you can easily DIY with the help of an interior door soundproofing kit.

#7 Attach Door Sweeps

Door sweeps are an effective way to soundproof an interior door. They are strips of rubber or vinyl that fit along the bottom of a door and provide an extra seal. Door sweeps are designed to block out noise, dust, and other unwanted elements from entering a room through gaps between the door and the floor.

When selecting a door sweep for soundproofing, look for one specifically designed for this purpose. For example, some door sweeps may need to be thicker or flimsy to block sound effectively. Additionally, make sure the sweep is the right size for your doorway.

To attach the door sweep to your interior door, use a drill to make pilot holes in your door frame and then screw in screws or nails through these holes into the frame. Be sure not to over-tighten screws, which can damage your door frame.
