If you have French doors in your home, you may love the way they look and the natural light they let in. 

However, if you live in a noisy area, you may also be all too aware of how much sound can enter through those doors. 

Fortunately, there are ways to soundproof French doors and reduce unwanted noise. 

In this guide, we’ll explain how to soundproof French doors and help you create a more peaceful and comfortable home.

Understanding Soundproofing

Before we dive into specific soundproofing solutions, it’s helpful to have a basic understanding of how sound travels and how it can be blocked or absorbed. 

Sound travels in waves, and when those waves reach a solid object, they can be reflected, absorbed, or transmitted through it. 

When we’re trying to block or absorb sound, we want to reduce the amount of sound that is transmitted through the object, in this case, the French doors.

Two important ratings to be aware of when it comes to soundproofing are STC (Sound Transmission Class) and OITC (Outdoor-Indoor Transmission Class). 

STC ratings measure how much sound is blocked by a given material or assembly, such as a door. 

The higher the STC rating, the better the sound-blocking ability. OITC ratings measure how much sound is blocked by exterior walls, windows, and doors in relation to the amount of sound heard outside the building. 

OITC ratings are typically used for commercial buildings, but they can be helpful for residential soundproofing as well.

Identifying the Problem Areas

The first step in soundproofing French doors is to identify where sound is entering. 

To do this, you’ll need to listen carefully for areas where sound is most noticeable. 

Common problem areas for French doors include gaps around the edges of the doors, gaps between the doors and the frame, and the glass panels themselves. 

Once you’ve identified the problem areas, you can start exploring different soundproofing solutions.

Solutions to soundproof french doors

There are several different methods for soundproofing French doors, each with its own pros and cons. 

Let’s take a look at some of the most common options.


Weatherstripping is a simple and affordable way to seal gaps around the doors. 

You can purchase adhesive-backed foam weatherstripping or silicone weatherstripping to create a tight seal between the doors and the frame. 

Be sure to measure carefully and cut the weatherstripping to the right length for your doors.

Door sweeps:

Door sweeps are another effective way to seal gaps at the bottom of the doors. 

These can be made from materials like rubber, vinyl, or neoprene and attach to the bottom of the door with screws or adhesive.

Acoustic curtains: 

Acoustic curtains are thick, heavy curtains that can help absorb sound and reduce echoes. 

They’re easy to install and can be a stylish addition to any room. 

Look for curtains with a high NRC (Noise Reduction Coefficient) rating for the best sound-absorbing ability.

Window film: 

If your French doors have glass panels, you may be able to reduce sound transmission by applying window film. 

This film can be applied to the glass and can help absorb or reflect sound waves.

DIY Soundproofing

If you’re feeling handy, there are some simple DIY soundproofing projects you can try. Here’s one option:


  • Weatherstripping
  • Acoustic sealant
  • Adhesive-backed foam
  • Tape measure
  • SScissors


  • Measure the gaps around the French doors and cut weatherstripping to the right length.
  • Apply acoustic sealant to the gaps between the frame and the doors to create a tight seal.
  • Apply adhesive-backed foam to the edges of the doors to fill any remaining gaps.
  • Install door sweeps at the bottom of the doors.
  • Test the soundproofing by standing outside and listening for any noticeable reduction in noise.

Hiring a Professional

If you’re not comfortable with DIY soundproofing or if you have a particularly challenging soundproofing situation, it may be worth considering hiring a professional soundproofing company. 

A professional can assess your situation and recommend the best solutions for your specific needs. 

They can also install soundproofing materials with precision and expertise, ensuring that you get the best possible results.

Maintaining Soundproofing Measures

Once you’ve soundproofed your French doors, it’s important to keep up with maintenance to ensure that your soundproofing measures remain effective over time. 

Regularly check weatherstripping and door sweeps for signs of wear and tear, and replace them as needed. 

Keep the doors clean and free of debris to ensure that they close tightly and don’t allow sound to leak through.


Soundproof French doors can be a great way to reduce unwanted noise and create a more peaceful home environment. 

By understanding the basics of soundproofing and exploring different solutions, you can find the best soundproofing methods for your French doors. 

Whether you opt for DIY soundproofing or hire a professional, taking steps to soundproof your French doors can make a big difference in the comfort and livability of your home.
