How to Soundproof French Doors

Weatherstripping your doors will help to keep out unwanted noise. Door seals and door sweeps will prevent air from leaking through your French doors and will also reduce noise. Hanging soundproof curtains on your French doors will block noise from outside sources such as traffic or neighbors’.

Soundproofing French doors can be done a number of ways, from sealing the gaps to installing a door sweep.

1. Weatherstrip the door

Weatherstrip the door

Weatherstripping is one of the most effective ways to soundproof French doors. If you want to keep sounds from coming in and going out, weatherstripping is a must. 

It can be installed between the doorframe and the door, which will help keep unwanted noise out. Weatherstripping can also be used on the bottom of the door to keep sound from getting in.

Here are some of the most common types of weatherstripping for your doors.

Vinyl Weatherstripping

Vinyl weatherstripping is a reliable and affordable option for soundproofing your doors. Vinyl is durable, cheap, and comes in a variety of colors that can match any decor. It’s also easy to install, making it an ideal choice for anyone who doesn’t want to spend too much time or money on their door soundproofing project.

Vinyl weatherstripping is often placed around the door frame. This keeps outside noise from entering your home through the bottom of the door or around the jamb.

Reinforced Felt Weatherstripping

Reinforced felt weatherstripping is one of the most common types of door weatherstripping. It’s durable, reliable, and relatively easy to install.

The most important thing to know about reinforced felt is that it comes in two varieties: open-cell and closed-cell. 

  • Open-cell weatherstripping is more flexible than closed-cell and tends to be better for doors that are opened frequently, like storm doors or patio doors. 
  • Closed-cell can be used in any type of door, but it might not last as long if your door gets a lot of use.

Reinforced felt weatherstripping can be cut easily with scissors or a utility knife. Just make sure you’re cutting through the whole length of the strip at once so you don’t end up with an uneven fit.

Metal Weatherstripping

Metal weatherstripping is a good option if you’re looking for soundproofing and privacy. Metal weatherstripping is durable, so it will last a long time, and it’s also very effective at keeping out noise. The downside is that it can be hard to install and may require extra tools or modifications to your door frame.

Note: Metal weatherstripping is often thicker than other types of weatherstripping, which means that it doesn’t always fit perfectly into all types of doors.

Rubber Weatherstripping

Rubber weatherstripping is a great choice for doors that are not in direct contact with the outside. It’s easy to install, and it comes in a variety of widths. Rubber weatherstripping is also very durable, which means it can be used on doors that get a lot of use without wearing out quickly.

It’s important to note that rubber weatherstripping is not effective at blocking sound when installed over doors with glass panes or windows, since the material will not stop sound from passing through it.

How to Install Weatherstripping on a French Door

  1. Measure the width of your door frame and purchase the appropriate weatherstripping for it.
  2. Remove the existing weatherstripping on the door frame, if there is any, using a flathead screwdriver.
  3. Place a dab of glue on one side of your new weatherstripping, then press it into place over the gap in the door frame.

2. Add a Door Gasket (Weatherstripping Alternative)

Add a Door Gasket

A door gasket is an alternative to weatherstripping, which usually only comes in one size and doesn’t fit every door. A door gasket can be adjusted to fit any size door, and it’s easy to install. 

A door gasket is an easy-to-install rubber or foam strip that fits between the two halves of the door. It seals the space between the two halves of your French door, preventing noise from escaping as well as keeping outside air out.

It is important to find one that is made of high-quality materials. One of the most important aspects of this type of door is its ability to keep out cold air while preventing sound from getting in or out.

The best way to do this is by choosing a door gasket with a high R value, which will help insulate against heat loss as well as sound transfer.

You can also choose between foam or rubber options depending on your needs. Foam gaskets are typically more expensive but also more durable than rubber ones.

How to Install Door Gasket

  1. Remove the old gasket by pulling it away from the door using a putty knife.
  2. Clean the area around the door with a degreaser such as vinegar or alcohol to make sure you get all of the old adhesive off of the door.
  3. Apply a thin layer of silicone caulk around the perimeter of where you want your new gasket to go. 
  4. Place the door gasket on top of that layer of caulk and smooth it down with your finger or an applicator tool.

3. Install Door Sweep

Install Door Sweep

One of the most effective ways to soundproof French doors is to install door sweeps. Door sweeps are thin pieces of rubber that attach to the bottom of a door, and they help reduce the amount of sound that passes through it.

When you’re installing a door sweep on French doors, make sure to measure the length of your doors first. You’ll want to make sure that the sweep fits both doors evenly so that they close smoothly without any gaps in between them.

If there’s an uneven gap between the two doors when they close, this will disrupt the seal between them and allow air into your home through gaps around those doors.

How to Install Door Sweep

  1. The first thing you need to do is measure for the door sweep. The length of the door sweep should be equal to the width of your doorframe.
  2. Use a hacksaw to cut through the metal part of the door sweep, then use sharp scissors or a utility knife to cut through the flexible flap.
  3. Place the sweep on top of your French door and mark where it will need to be secured into place with a pencil.
  4. Attach the sweep to the top of the door by using screws and a drill.

4. Install Automatic Door Bottom (Door Sweep Alternative)

Automated door bottoms are great because they’re easy to install and work well. They can be attached to your door and the floor so that when you close it, the bottom of the door will automatically be lowered and cover up any gaps. 

The best part is that they won’t get stuck in the doorway or jam up on you. They’re also very easy to adjust if you want to change the height of your door so it fits better with your other doors.

5. Hang Soundproof Curtains

Hang Soundproof Curtains

Soundproof curtains are made specifically to absorb sound, so they’ll be able to cut down on the amount of noise that gets through them. They’re designed with a special fabric that has been tested and proven to absorb sound.

Soundproof curtains can be hung on either side of the door, or both sides if you want to block noise from both directions. It’s important to hang them as close to the floor as possible.

Which material to choose for soundproofing?

The key to a good-sounding curtain is choosing the right material. If you’re going for maximum sound reduction, look for thicker fabrics like velvet and wool. These materials are dense enough to block out some noise and prevent it from passing through the curtain.

If you’re looking for something more lightweight and less expensive, try cotton or silk instead. These fabrics aren’t as dense as velvet or wool, but they’ll still do a decent job of blocking out some noise and preventing it from passing through the curtain.

How to Hang Soundproof Curtains on French Doors

  1. Measure the door size and add 2 inches to each side.
  2. Buy some soundproof curtains that match the door size and have metal grommets in them.
  3. Attach the curtain rod to the wall with a drill, making sure the curtain rod is level and straight.
  4. Insert a grommet into each end of the metal curtain rod.
  5. Hang up your new soundproof curtains.

6. Place a Door Rug

Place a Door Rug

A door rug is a great way to soundproof French doors. These rugs are designed to absorb the sound from outside the door. When you install a door rug on your French doors, the rug will absorb some of the sound that comes through the door and keep it from getting into your home.

If you place a door rug on both sides of your door, it will help to block out more noise than if you only put it on one side of the door.

Door rugs come in many different colors and styles so that they can match any decor in your home. They are easy to install and do not require any special tools or skills to do so. 

7. Use Grease for Squeaky Sounds

Use Grease for Squeaky Sounds

If you have a squeaky door, you may be able to fix the problem by lubricating its hinges and handles.

A squeaky or loose French door can be fixed by simply adding a little bit of lubricant to the hinge and handle. Any type of oil will work, but silicone grease is the best option because it lasts longer than most greases and oils.

8. Apply Soundproofing Paint

Apply Soundproofing Paint

Applying soundproof paint to the French Door is not the most efficient way to block out noises from outside, but it can help when used with other methods.

Soundproofing paint is a special type of paint that has been created for the purpose of reducing noise. It’s made with materials that are more dense and heavy than traditional paints, so they absorb more sound before it can travel through the material.

Soundproofing paint works by creating a thin layer over the surface of your door that absorbs noise instead of reflecting it. This makes it much easier to block out some sounds from outside.

9. Replace with a Double Glazed French Door

Replace with a Double Glazed French Door

The best way to soundproof French doors is to replace them with a double-paned French door. This will significantly reduce the amount of sound that gets through, because it will have two panes of glass instead of one.

Replacing your old French doors with new double-paned ones is an excellent way to make your home quieter and more energy efficient. The glass on double-paned doors is typically much thicker than that of single-paned doors, which means that they block out more noise and usage.

Additionally, double-paned doors are much more energy efficient than single-paned ones. Single panes of glass are prone to letting cold air escape through them during winter months (and hot air during summer months). Double panes are much better at keeping heat from escaping through their frames as well as keeping cool air from coming.

Acoustic Curtains for French Doors

Acoustic Curtains for French Doors

French doors add a touch of elegance and sophistication to any home, but they can also let in unwanted noise from the outside. If you’re looking for a cost-effective way to soundproof your French doors without compromising their aesthetic appeal, acoustic curtains could be the perfect solution.

What are acoustic curtains?

Acoustic curtains, also known as soundproof curtains or noise reduction curtains, are specialized curtains designed to absorb sound waves and reduce noise transmission. They’re made from dense, heavy materials such as multiple layers of fabric or mass-loaded vinyl, which block out sound and prevent it from passing through the curtain.

How do acoustic curtains work for French doors?

Acoustic curtains can be used to cover the entire length of the French doors or just the glass panels, depending on your needs. When hung properly, they create an airtight seal around the door frame, preventing sound from entering or leaving the room.

The curtains work by absorbing sound waves as they pass through the material, converting the sound energy into heat and reducing the amount of noise that gets through.

Tips for selecting and installing acoustic curtains

When selecting acoustic curtains for your French doors, there are a few things to consider. First, make sure the curtains are heavy enough to block out sound effectively. Look for curtains with a high noise reduction rating (NRR) or sound transmission class (STC) to ensure maximum soundproofing.

It’s also important to choose curtains that fit your French doors properly. Measure the width and height of the doors carefully and select curtains that are slightly larger than the opening to ensure a tight seal.

To install the curtains, you’ll need a sturdy curtain rod and brackets that can support the weight of the heavy fabric. Make sure the curtains are hung tightly against the door frame to prevent any gaps or leaks that could allow sound to enter or exit the room.

Other benefits of acoustic curtains for French doors

In addition to reducing noise, acoustic curtains offer several other benefits for French doors. They can help regulate the temperature in your room, keeping it cooler in the summer and warmer in the winter. They also provide privacy and light control, making them a versatile option for any room in your home.

Overall, acoustic curtains are a cost-effective and stylish way to soundproof your French doors and create a quieter, more peaceful living space. With the right curtains and installation, you can enjoy all the benefits of your beautiful French doors without the unwanted noise.

Why Soundproofing a French Door Is Important?

Reducing noise is one of the most important things you can do to make your home more comfortable. Whether you’re trying to sleep or work, you’ll find that soundproofing a French door is an effective way to reduce noise and make your space quieter.

A soundproof door can be helpful in these situations:

Reduced Noise

The best part about soundproofing your French doors is that it can reduce the noise in your home. When you are trying to get work done or just relax, you don’t want to be distracted by sounds coming from outside of your home.

Soundproofing a door will help keep those sounds out while keeping the noise inside of your home at a manageable level.

Temperature Insulation

Soundproofing your door helps prevent drafts from coming in through the cracks and gaps between the door and its frame. That means that you can keep your home warmer during the winter months, which will save you money on heating bills and make it more comfortable to live in.

Keep Out Pollutants

There are lots of ways for pollutants like dust and pollen to get into your home through vents, cracks in window sills or walls, gaps around doors, and even through doors themselves. That’s why soundproofing a door is important: it keeps all those nasty little particles from entering your home.

How Sound Travels through French Doors?

Sound is a form of energy that travels through air. It’s created when a vibrating object (such as a drumstick, guitar string, or vocal cords) moves the air molecules around it, creating pressure waves in the air. 

Those pressure waves move through the air at different speeds depending on their frequency. The higher the frequency, the faster the wave moves through space.

Airborne Noise

Airborne noise is a type of sound that can travel through the air and be heard by your ears. It’s made up of low and high frequencies, which are easily picked up by our ears. Airborne noises are usually caused by machines, animals, or people.

When the noise is coming from the bottom of a French door or from cracks and gaps in the door, it’s usually caused by airborne noise.

Impact Noise

Impact noise is the sound generated when a surface impacts another surface. It can be caused by anything from dropping a heavy object to using a mallet to strike a drum.

For example, when someone knocks on your door.


The best way to soundproof a French door is to replace it with a double paned French door. This is because the double paned doors have two layers of glass and a space between them. This space allows for insulation, which can reduce the amount of noise coming from outside.

A French door is a great way to bring more light and air into your home. But if you’re like most people, the sound of the wind blowing through the door can make it impossible to hear what’s going on in the rest of your house. 

We’ve talked about some ways you can improve the soundproofing of your French doors, but we hope that this article has given you some ideas for how to make them even better.

Frequently Asked Questions (Soundproof French Doors)

Can French doors be soundproof?

You can make your French doors more soundproof by installing a door sweep in the bottom of the doorframe. This will keep sound from traveling through the airtight space between the two doors. Install weatherstripping on the door to create a tight seal between them and reduce noise.

What type of door is most soundproof?

The most soundproof doors are those that are made of solid wood and are insulated with fiberglass. These doors have a high mass, which means they will absorb sound, and the fiberglass will act as a dampener for any sound that does manage to get through.

What is the cheapest way to soundproof a door?

The cheapest way to soundproof a door is to seal the gaps between the door and the frame, and use weatherstripping around the edges. It’s important to note that this won’t completely eliminate noise. It will help keep it out, but there are still some sounds that will get through.

If you’re looking for a more permanent solution, you can install panels on all sides of the door using screws or nails, but then you’ll need a drill and an electric screwdriver.

How do I stop the sound coming through my door?

Door sweeps help you keep sound from coming through the door. They are small pieces of metal or plastic that attach to the bottom of a door and block out ambient noise. People outside can’t hear as well what’s going on inside your house.

If this isn’t an option, try hanging thick curtains on either side of the door or draping blankets over them. This will also absorb some of the sound and reduce its volume. 

You could also try placing rubber mats on either side of your doorway to muffle any sounds that do get through.
