How to Soundproof French Doors
In today’s homes, French doors have become a must-have feature. In fact, these doors are specifically intended to offer that strong aesthetic appeal if you want class and beauty. They are often thinner and bigger than standard doors. They’re also made of light materials, with glass panes running the length of the structure.
No matter how beautiful they are, you need to know how to soundproof French doors, because sound and other unpleasant noises can penetrate at any time. Moreover, all your secrets from inside the house are clearly audible from the outside. Thanks to the same beautifully thin glass. Do you need these risks?
In this article, we will show you how to approach and deal with the noise problem with your gorgeous French doors using easy, practical solutions.
Common Methods of Soundproofing
There are four primary techniques used to muffle different sources of noise. Each approach will yield some results, but when two or more methods are combined, better results are generally obtained.
| 1. Increasing the mass or density | Sound waves are made more difficult to vibrate by making things heavier and thicker. If they are unable to travel, they become quiet. We’ve discussed this in our article How to Soundproof a Studio. For example, adding layers of drywall to a wall will reduce sound transmission, especially at higher frequencies. A French door’s bulk is efficiently increased by adding additional glass. |
| 2. Damping | Sound will seek the shortest path possible through solid objects. You may make it more difficult for sound waves to move by separating studs and joists in walls, floors, and ceilings. Secondary glazing traps air between the panes, reducing the strength of sound waves. |
| 3. Decoupling | Sound will seek the shortest path possible through solid objects. You may make it more difficult for sound waves to move by separating studs and joists in walls, floors, and ceilings. Secondary glazing traps air between the panes, reducing the strength of sound waves. |
| 4. Absorption | Sound waves are trapped and allowed to vibrate in open cells in woven fabrics. Many materials absorb noise effectively, but they don’t eliminate it. Instead, they mute it. Sound absorption may be achieved by using soundproofing drapes and blankets over French doors (more info about sound-absorbing materials on soundproofliving.com). |
Ways to Soundproof a French Door
Lighter materials, in contrast to heavy materials, are notoriously difficult to soundproof and let in a lot of noise. This is why windows tend to be a soundproofing gap in space, and why you should take these procedures before trying to fix your French doors:
| 1. | Examine everything carefully and see if there are any other sources of sound leaking that can be isolated from your French doors. |
| 2. | Check any windows in the room, since they might pose a considerably greater concern than even a totally glass door. |
| 3. | Look for any cracks that need to be filled not only around the entrance but throughout the room. These are frequently neglected, despite the fact that they can create excessive noise at times. |
| 4. | Check all air vents to make sure they aren’t transmitting noise, since if they are, no amount of additional soundproofing in the room will help. |
So, How to Soundproof French Doors?
Soundproofing French doors is a difficult task to do. Due to the significant amount of glass in the doors, it is hard to completely eliminate noise. Every door has a little gap around the edges, but French doors have an extra one running down the middle. This is merely another place where sound may enter.
Many effective methods, on the other hand, offer extremely considerable sound reduction results. The techniques differ, some are inexpensive and simple to do, while others are not. Here are some of your options:
1. Check the Installation
You could be thinking to yourself, “Surely this has been done before”. They’ve been checked before, whether when they were installed or afterward, so, everything is OK, right? If you believe that, you are wrong! In comparison to virtually any other style of door, French doors are delicate and frail. It’s why they appear so good.
While this fragility is appealing, it can be a huge disadvantage when it comes to installation. They may even produce noise as a result of this in the following ways:
- Due to poor placement, they do not absorb vibrations.
- They rattle, adding to the loudness.
- Too many cracks develop, allowing noise to get through.
These, and a thousand other minor problems, are why you must be extremely thorough in your approach. If you overlook anything, the situation will definitely worsen in the future.

2. Fill the Gaps
The path of least resistance is always traveled by sound. Consider changing your locks, knobs, and hinges if they are old or broken. For the best noise protection, all exposed gaps on your French doors should be filled. To begin, identify and fix any gaps in the frame or the doors. Consider items that not only absorb sound but also help to insulate your home:
- Soundproof weatherstrips
- Door sweeps
- Draught excluder
- Purchasing French Doors with Laminated Double or Triple Panes
This is the point at which costs begin to rise. Because single-layer glass has a low STC rating, it offers a minimal sound barrier, thus adding a second or third layer is the best method to filter out unwanted sounds. This is a massive endeavor that needs a certain level of expertise as well as a significant amount of time.
A common and efficient sound barrier is secondary glazing with a laminate layer. It’s also more secure than regular glass since it’s more difficult to shatter. Without knowing the specific installation, it’s difficult to give an accurate estimate of laminated glass’s noise reduction capabilities. Likewise, the thickness and size of the layers will enhance the bulk and dampening abilities of the structure.
3. Seal and Strip
Sound will react similarly to the air that carries it. Air has a tendency to enter and exit through any and all openings it may discover. That is why, unless you have no noise problems, this is the most beneficial step that we recommend you take regardless of what else you do.
Simply said, this increases your odds of effectively reducing any noise that enters through your French doors. Generally speaking, you should:
- Wrap the door frame with stripping.
- Fill the gaps between the door and the frame with stripping.
- When all other probable leaks are ruled out, these are the two main approaches to get a satisfactory outcome using the methods listed above.
To begin, check to determine whether there is any existing stripping and if it is worn. It’s possible that the issue is just that it’s worn down, in which case you can easily replace it.
Then you gently apply the stripping to your French doors. Always cover as much as possible rather than blocking anything; otherwise, you’re not accomplishing anything.

4. Install Soundproof Curtains
Any type of thick, dense cloth draped across French doors will muffle much of the noise entering the room. Without eliminating all noise, soundproof curtains or noise-reducing curtains are meant to absorb excessive noise and decrease reverberation (echo).
Curtains that are thicker and denser will absorb more sound. They are frequently fashioned of Molton and wool materials, which provide excellent blackout and insulation. Greater absorption is provided by thermal linings and layers with more fibers.
If it’s practicable, buy drapes that are three times the width of the door and a few inches longer. By draping more cloth on the pole, you may reduce the amount of sound that gets through.
DIY soundproofing is also possible to create your own soundproof curtains. Stitch the three layers together by sandwiching a thick piece of wool between two heavy drapes or pieces of cloth. As a consequence, the tri-ply drapes are highly effective.
A heavy-duty rod across the top of the door frame is required for installation. Make sure it can withstand the weight of thick curtains. Double track rods can be used to hang two sets of curtains at the same time. With more mass, the sound is reduced more effectively.

5. Use Soundproofing Blankets
Blankets are a good option if you’re looking for a quick fix to a noise problem (We mentioned this in our article How to Soundproof a Garage Door). They provide an immediate benefit, although they aren’t the most aesthetically pleasing option.
High-frequency noises are more effectively muffled by blankets than low-frequency sounds. They are made of thick fabric packed with layers of soundproofing materials, most often fiberglass, and are clearly meant for function rather than aesthetics. When moving houses, blankets are frequently used to cover heavy and costly furnishings.
6. Double the Technique
This may be the most effective technique, but it is also the most costly. Essentially, you’re doubling the measures you employed previously, such as putting up soundproof curtains on both sides of the door or doubling the doors themselves.
The unexpected benefit of doubling the doors is that it creates a small air pocket between them that absorbs noise. Yet, the inconvenience of two sets of doors in a row is the least of your worries, other than having to pay twice.
Even so, it’s still less expensive than double-glazed doors. These are the most elegant and efficient solutions, and they don’t require anything else. The problem is that they’re also the most expensive option for repairing things. The costs of replacing the old doors are insignificant in comparison to the hundreds of dollars that modern French doors may cost.
In Conclusion
The effectiveness of soundproofing French doors, like many other things in life, may be determined by the size of your budget. However, you should be able to successfully limit noise transmission by utilizing a door sweep, filling a gap, and hanging soundproof drapes or blankets.
You can enjoy the elegance of French doors while also reducing noise. Silence does not have to mean sacrificing style. When purchasing or soundproofing your French doors, be sure to follow the techniques we mentioned above, and rest easy knowing that nothing will be able to disturb your peace and quiet!
