In the vast majority of houses, sliding doors are only found on the back deck. Just a few of these doors are effective in reducing ambient noise, while the others are woefully inadequate. One thing that all of these scenarios have in common, however, is that there are ways to improve the soundproofing of sliding glass doors, and that is what I will be discussing in this piece. 

Weatherstripping and specialised door sweeps are the most effective methods for reducing noise from a sliding glass door, but there are numerous more. 

Keep reading to learn more about how to lessen the noise that seeps in through a glass door. 

Attempting to soundproof a glass door is a hassle since you’ll need to cover the glass in some manner to prevent noise from leaking through. Obstructing the view through a glass door, of course, renders the door mostly ineffective. 

Sliding glass doors, both inside and out, will be a major point of emphasis. Sliding glass doors are a major source of noise pollution, which is why many want to silence them. Wood doors, on the other hand, may be easily muffled by purchasing one that is simply thicker and more robust. 

Several strategies for reducing noise transmission via a glass sliding door will also be discussed. The process of soundproofing a sliding door is substantially more involved than that of a standard swinging door.


Internal and External noise Reduction Strategies for sliding glass doors


Step 1: Be Careful to Caulk the Holes 

The first order of business is to fix any weather or age-related leaks around the sliding door. Eliminate any spaces that might allow noise to enter. 

Put your hand through the crack in the door and gently go on. When an intruder enters a room, the chilly air that meets your skin (in colder regions) is a telltale sign. 

The amount of noise that enters a house via even a little break is dramatically affected. Make use of soundproof caulking to ensure a tight seal. 

One advantage of this caulking is that it can be easily reshaped to fix any gaps that may appear in it over time. 

Step 2: Use Door Sweep To Lessen Noise Levels

Installing a miniature door sweep may also be an effective means of preventing drafts from entering through the bottom of an inside sliding glass door. From the kitchen, you may access the laundry area through a glass sliding door. You may reduce the amount of noise from the washer and dryer by installing a sweep. 

While it’s possible that a better door sweep exists, you do not have to worry if the one you purchased serves your needs just fine. The fact that it is self-adhesive and so thin made it the obvious choice for my door. 

As a result of its minimal thickness, the door may nevertheless be moved effortlessly inside its wall-mounted track. 

This door sweep is not only cheap but can be easily installed by the homeowner as a means of soundproofing the home.


Step 3: Handle the Weather Stipe with Extra Care 

Sliding glass doors in the inside might benefit from specific weather strips. Making ensuring the weatherstrip isn’t too thick is the only real concern here. Too much thickness in the strip will make the door harder to open and close. 

The weatherstrip must be thick enough to prevent the noise from the door’s threshold from entering the room. 

Choose a weatherstrip with adhesive backing for quick and simple installation at the bottom of the sliding door. Opening and shutting the door should be a breeze with the foam underfoot. 

Step 4: Acquire heavy drapes that dampen noise  

There is probably already a drape hanging in front of the sliding glass door that leads outside, and this will serve to dampen some of the noise from the street. 

If you like, you may replace it with a heavier curtain that is designed to keep out both light and sound. 

As few people are eager to permanently install curtains in their homes, this approach is not ideal for use on an inside sliding door in an attempt to reduce noise. If that’s the case, you may as well replace the glass door with a wooden one. 

Make sure the length of the curtain you choose is sufficient to reach the floor. The soundproofing properties of the curtain would be nullified if there was a space between the curtain and the floor.


Step 5: Keep the noise out with a blanket 

A soundproof blanket on a sliding door may be an inconvenience if you often use that door, but it might be useful if you need to filter out sounds while you work. 

The usage of moving blankets is another option, but how would you hang them? The inclusion of hanging holes is a nice touch for these soundproof blankets. Add metal reinforcements every 9 inches along one side of the holes to ensure equal suspension. 


Step 6: Get Thick Blinds

Seeing a YouTube video detailing the installation of a certain sort of thick, contemporary blinds on his glass door is required. You can see how they function in demonstration movies, and if you install blinds together with soundproof curtains, the noise level in your home should drop even more.

Step 7: Add another glass sliding door right away!


We have also experienced firsthand how well placing a second sliding glass door in front of or behind the current one works, despite the fact that this solution is seldom discussed. 

The second door greatly improves the home’s noise insulation and security. 

With the installation of a second door, you may effectively block the chilly airflow that previously entered via the sliding door. A room with an entrance like this is likely to be the draftiest and coldest in the house. 

Given that the glass does an inadequate job of keeping the cold out, installing a second pane here would make this the coziest room in the home.


Benefits of Using Sliding Glass Doors 


  1. There is a decrease in ambient noise of at least 75% and, in some cases, as much as 95%. 
  2. With a soundproof sliding window or door, you may save money on heating and cooling.
  3.  Laminated glass doors considerably improve safety. Sliding glass doors, often composed of tempered glass, are a common target for burglars. Laminated glass makes it harder for would-be thieves to break in since it is both more time-consuming and more noticeable when broken.


Frequently Asked Questions: FAQs

To what extent may sliding windows be protected from outside noise? 

Using a self-adhesive foam tape is one of the simplest do-it-yourself methods of soundproofing windows in the house. Much as acoustic caulk may be used to seal the gap where a window meets a wall, foam tape can be used to seal the spaces surrounding a window frame. 


Is it true that soundproof drapes don’t let any sound through? 

In order to prevent noise that has already entered a room from rebounding, sound deadening or absorption might be used. Soundproof curtains, as reported by a number of reviewers, are excellent for sound deadening but are useless for reducing ambient noise. 


What can I do to lessen the slamming sound of my door when it’s shut? 

Even if the door’s hinges, sweep, and weather stripping are all in excellent shape, you may reduce the amount of noise it makes by taping foam or rubber around the door frame. You may also use little felt pads on the top and bottom of the frame. As the door closes and hits the frame, they act as a cushion to reduce the impact. 


Where can I get quieter curtains? 

The ideal soundproof curtains for a home office may be crafted from burlap or another dense fabric that gives the impression of being more refined, like linen. Curtains with a basketweave pattern are likewise a classy choice. 

Is there a reason why sliding doors generate so much noise? 

Squeaky sliding glass doors are a sign that the track and rollers need to be lubricated. A sliding door may create noise when opened and closed if it has been modified improperly, is dirty, or has been exposed to water. A squeaky door with worn rollers causes delays in the door’s movement up and down the track.


Final Words 

If you follow all of these instructions, the quantity of outside noise that enters via the door should be drastically reduced. 

You shouldn’t hesitate to give this a go, since the majority of the actions here don’t call for specialized knowledge or a hefty financial outlay. More details may be found in the relevant articles we provide below:
