How to Deal With Thin Walls

If your apartment walls are so thin that you can hear your neighbors whispering, then it is time to do something to stop those unwanted noises and sounds. Luckily, it is rather simple to soundproof apartment walls. In order to do it properly and correctly, we recommend you get familiar with a complete wall soundproofing guide you can find below. 

In this step-by-step instruction, you will find recommendations about preparations for the procedure and all the materials you will need. And of course, we will walk you through each step carefully!

For soundproofing thin walls in your apartment, you will first of all need to get a few things ready. We talk about soundproofing materials. They can help control the acoustics in your space and absorb any noise coming in through your thin walls. You will likely need a combination of popular soundproofing materials, including the following items:

  1. Green glue
  2. Foam mats
  3. Soundproof paint
  4. Mass-loaded vinyl

Once you have everything you need, you can start going through the wall soundproofing procedure. Make sure you follow the steps one by one, and you will end up with walls that let no noise from the apartments around you.

Target the Weak Points of the Walls

The very first thing you will have to do is to target the point where your home walls let most of the sound into your apartment. Simply scout for the weakest parts of your walls when it comes to noise. What shall you look for in particular?

Keep in mind that some parts of the walls may be initially thinner than others. Besides, in some areas, your home walls may have a lot of piping, which will also create an impression of a hollow wall. These bring in the most noise and are thereby in dire need of soundproofing.

Look for Possible Holes and Seal Them

Another cause for hearing annoying sounds is that there may be holes in your apartment walls. They serve as gateways for external noise sources to get inside, more so, if your apartment has thin walls.

And it doesn’t mean you have to look for any big holes! Even the tiniest ones that easily go unnoticed emit surprisingly massive amounts of noise. So, apparently, you need to seal them. There is a wide range of sealing substances on the market, but green glue is the one that will do the job perfectly. The best thing about this glue is that it not only seals the holes. In addition, this glue will also help you a lot with soundproofing them!

Don't Forget About the Mass-Loaded Vinyl 

It is one of the best insulating materials that will keep external noise out of your apartment. Moreover, vinyl mats are a beast in reducing airborne noise in your home, which makes your home much quieter. 

And there is another benefit that will surely make you want to buy these! Did you know that mass-loaded vinyl mats also make your house warmer? This makes them ideal for winter because they are thick and will cover your walls as a blanket. So, they double as a thermal and soundproof solution. 

Fill Out Your Apartment With Some Furniture

This recommendation is more suitable for homes that are spacious and have echoes typical for empty rooms. So if you live in such an apartment and you suffer from noise, the solution is to fill up your rooms with furniture. It will help you eradicate the bouncing off of sound across the walls and floor. 

What about the type of furniture that should be used, you may wonder? You will probably be very surprised to learn that regular bookshelves filled with books are one of the best ways of soundproofing thin apartment walls! So, the more walls they fill up, the better. Like that, you will have a double benefit: rooms protected from noises and books that you can enjoy! 

However, if you don’t feel very enthusiastic about turning your home into a library, then it‘s ok if you use beautiful wall arts instead. They will do the trick. 

Install Foam Mats

You have definitely seen those. They are often used in recording studios and music rooms, and they will surely do the trick. Soundproofing foam mats cut out noise from your apartment by up to 50% and mesh well with a soundproofing wall kit to eradicate even the loudest and most annoying noises. 

And here is a tip for you: when purchasing these soundproofing mats, keep an eye out for those with eyelets or grommets because they make the installation process much easier. Also, those residing on the floors above the first floor of an apartment can consider installing these blankets on their floors as well.

These foam mats will certainly help you cope with unwanted sounds and noises. And besides, they are affordable. The best thing about foam mats is their top-notch insulating power. They prevent thermal loss and soundproof your apartment. Furthermore, since they are mostly made of rubber foam, they are resistant to petrol and oil.

Use Soundproof Wall Paint

Thanks to its thick texture, covering thin apartment walls with soundproof paint will provide you with a more quiet environment. So, if you have begun hearing small noises seeping into your home through the walls, then perhaps it’s time for some painting. 

In addition, this paint will also give your apartment a new look since it’s just like any regular wall paint, but with an added advantage. This makes it a simple and cost-effective solution to our noise problems.

Like this, now you know what to do if you need to fix the thin walls in your home. As you could notice, the tips we shared with you are rather easy to apply and most materials that you might need are more or less affordable. Besides, this soundproofing procedure will have to be done only once. And as a result, it will become a worthy investment in your future peace and relaxation.

Benefits of Soundproofing Thin Walls In Your Apartment

For sure, the major benefit is that, after soundproofing your interior walls, you will be protected from any noises and strange sounds coming into your apartment from the street of from the apartments around you. However, you might not be aware that a soundproofed apartment also offers plenty of additional perks to apartment dwellers! These perks typically include the following:

  • Better privacy. Keeping outside noises at bay will give you greater peace of mind since you will know that your neighbors won’t be able to overhear your conversations
  • Improved quality of life. Loud neighbors can be irritating, especially if they tend to fight often. So soundproofed walls will protect you from their quarrels
  • Better sleep. Odd noises lead to disturbed sleep. Soundproofing your apartment ensures you won’t be bothered by any sounds from the outside. It will allow you to relax and enjoy your personal space

So if you suffer from irritating neighbors next door or busy traffic right under your windows, soundproofing your apartment is exactly what can save you. You will just need to spend some time applying the soundproofing materials to your walls, and you will be able to enjoy silence finally.

Tips For Further Sound Reduction

Once you have determined a budget, pointed out the areas of your apartment that are especially noisy, and prepared all the materials you will need, it is time to get to work. We suggest you check out the following five tips that will help you reduce your sound levels quickly and inexpensively.

Stack Furniture Against the Walls

We have already mentioned above that placing more furniture in your apartment can reduce the amount of noise in it. But if the space is not very big, then more furniture will only make it messy! So what shall you do? In this particular case, the trick is slightly distinct. 

The way to a quieter place might be as simple as some interior redecorating. Simply stack big pieces of furniture, like wardrobes and bookshelves, against your wall to add mass. You can even place thick blankets or foam padding between the furniture and the wall to further absorb any sound.

Like that, any sounds and noises will be “stuck” in these objects, being unable to fill your room with echoes like they used to do before.

Cover Your Walls With Absorbent Materials

Soundproofing curtains or even thick blankets can become an easy and cheap solution to soundproof thin walls. You can stick them with mounting putty if you want it to be done safer, or you may use nails if you are not concerned about wall damage. In addition, acoustic foam panels come in all shapes, sizes, and levels of thickness to effectively keep noise from exiting or entering.

Add a Layer of Drywall

Adding an extra layer or two of drywall is a relatively easy way to soundproof your thin walls and create a few extra layers between yourself and any sources of noise like your neighbors or cars. If you are renting an apartment, you’d better check with your landlord first to make sure this is acceptable and you won’t be fined for that later.

Seal Visible Holes or Cracks

As you already know, even the smallest gaps and cracks can make a big difference when it comes to noises. Inspect your walls for any visible holes and seal them to help block noise. It is the least that can be done to reduce the level of noise in your apartment.

Hang Rubber-Based Materials

Rubber-based materials and mass-loaded vinyl are fantastic ways to keep your space quiet. As an added bonus, these layers can help insulate your apartment and keep you cozy.

So, now you are aware of many useful things regarding soundproofing thin apartment walls. We told you how this procedure should be done, what materials you should use for that, what things to keep in mind, and even what else you can do in order to make your living space more comfortable.
