A home is a place where we can rest and feel in silence. However, sometimes the sounds outside the window distract us from relaxing. In this case, it’s better to know how to soundproof window. To do this, you need to do the following:

  • Replace the window plugs;
  • Apply a layer of silicone sealant between the plugs and the glass;
  • Remove excess parts with a spatula.

There are also many other methods. Each depends on the noise level that passes through your windows. Often, builders do not care for sound insulation when building a house or installing windows, so we have to correct such mistakes themselves. You can use a thick double-glazed window for loud noises, like cars and people on the street. For minor noises, you can simply seal the gaps around the windows with sealant. So, it is quite possible to block noise outside independently. You just have to do everything with the right approach and according to the instructions.

10 Ways to Soundproof Windows

These ways can include the installation of double-chamber windows, triplexes, and so on. The advantage of such options is that they help create a calm atmosphere in the house and avoid noise. That is why it is essential to have soundproofing windows. Each type has different sound insulation properties. Sometimes the level of noise insulation we have may not be enough. So, in such cases, you should do the following to reduce window noise:

1. Install Window Inserts

Are you tired of the loud noises coming from all the streets, or are your neighbors being too noisy? You can block any noise from your window with window inserts. They are installed into the window frame about 5 inches in front of the inside of the existing window. In this way, it is a barrier to any noise entering your room. To install them, you need:

  • Measure the window length and width;
  • The width should be measured at the top, bottom, and middle points. Choose the shortest size of the three, subtract 1/8 inch and remember that number;
  • Repeat the exact measurements with the height;
  • Next, you need to measure the diagonal of the window to understand whether it is straightforward enough;
  • After that, remove the existing window;
  • Insert the gasket for the window so that there is a small space around the perimeter between the window and the window insert;
  • Next, install the window inserts;
  • Secure the window.

If somewhere during installation you notice gaps, remove them with foam. It will additionally help reduce window noise.

2. Install Double-Glazed Windows With Increased Sound Insulation

For an old window, sound insulation can be improved by replacing the double-glazed window inserted inside the old frame. This procedure is cheaper than replacing the new structure of the window.

  • In addition, you can put noise-insulating double-glazed windows of the same thickness as the old models;
  • At the same time, there is an opportunity to increase soundproofing for windows by choosing a product with different thicknesses of glass and internal chambers.

Therefore, you can select the option that suits you best. For someone, a thin glass may be enough because they live in a quieter place, and for someone, a thicker one is needed because they live in the city’s center. So, be guided by this to decide on your option.

3. Install Triplex

The process of installing is like the installation of a usual window. But you need to be more careful so that you do not have drafty windows during installation. So,:

  • A triplex is a special layer between standard chambers, with the help of which the sound insulation of windows increases by 60-70%; 
  • It consists of one pair of 3 mm glasses;
  • Between them is an elastic polymer resin. Therefore, the total thickness improves the absorption of sound vibrations against noise from the street;
  • Thanks to it, even low-frequency sounds will not penetrate the house, and it’s how you can block noise from the window. 

In addition, triplex is considered the safest type of window glass. When breaking the canvas, fragments will remain on the film. So, it is recommended to use them in office and residential premises overlooking busy streets, noisy factories, railway tracks, etc.

4. Use Acoustic Sealant

Any sounds spread quickly and can pass through openings, even minor holes. It is for this reason that soundproofing windows are essential. One solution is to use an acoustic sealant in the form of silicone to insulate the space. When you choose it, you have to pay attention to the house’s construction materials, the type of window frames, and the thickness of the walls. The wrong selection will lead to the fact that you will not get the proper effect. 

So, you should use it in this way: 

  • Apply acoustic sealant around the window frame, from top to bottom, and on the sides;
  • Remove the plastic slopes and window sills;
  • Then look for possible gaps. 

If you overdo the application of this product, you will need to remove the excess after drying. The most important thing is to use acoustic sealant in those places where you see gaps to avoid noisy windows.

5. Install Double-Glazed Windows With Argon

Argon gas in double-glazed windows is used to minimize thermal conductivity and reduce sound permeability. The air gap between the layers of glass in the double-glazed window effectively reduces the volume of outside noise. It happens because the gas reduces the speed of propagation of sound waves.

Due to its higher viscosity, the room becomes noticeably quieter. However, this option is more suitable for those who do not feel the sounds very strong.

6. Hang Sound-Dampening Curtains

Sound-Dampening Curtains

These can be distracting, whether it’s cars, neighbors, or children playing when you try to fall asleep. Whatever the reason, sound-absorbing curtains can help you block out unwanted sounds. So for soundproofing windows, we recommend using floor-length curtains:

  • They can reduce the sound and provide you with quiet sleep and rest; 
  • Such curtains can be of different fabrics, for example, coats, overcoats, and acoustic fabrics; 
  • They can have different roughness, but choosing the rougher soundproof curtains is better; 
  • And, of course, you can select any color of them. 

Therefore, thanks to this, you can select sound-dampening curtains even so that they complement your interior. 

7. Soundproof Windows with Furniture

You can have soundproofing thanks to the correct arrangement of furniture in the room. First, it is effortless and does not require costs. And secondly, you can reduce noise and additionally create a space in a new way. You only need: 

  • Place heavy furniture near the window. It can be a wardrobe, a heavy sofa, or an armchair;
  • A good idea may be to hammer the shelves near the window,  which can be covered with books. This way, you can significantly block noise from the window because heavy furniture interferes with sounds. In general, only creativity is needed here.

8. Use Self-Adhesive Foam Sealing Tape

One of the most straightforward solutions for sound insulation of windows is using self-adhesive foam tape:

  • Similar to using acoustic sealant, foam tape can be used to seal the openings around the window frame; 
  • A good advantage is that this tape can be removed, so it is an excellent option if you want to increase the soundproofing of windows temporarily; 
  • But if you leave this on the windows for an extended period, you can easily tear off some of the paint or even the wood frame when it comes time to remove it. 

Therefore, do not store the tape for a long time. To increase noise insulation again, you can stick a new tape.

9. Change the Glass in Your Windows

Another option can be a simple glass replacement. It can also help avoid noisy windows if you choose the right glass. There may be several options for them:

  • Choose a rougher window than you have;
  • Install a window with more than two glasses;
  • When replacing glass, use a noise-insulating film which must be attached to the top of the window.

It is a straightforward option for soundproofing windows and, at the same time, effective. The main thing is to do it correctly so that new gaps do not form during installation.

10. Exterior Storm Windows

The next option may be to install windows outside the house. The presence of another layer of external glass will help reduce the noise of windows. If you put it on top of your window, you can form an invisible gap between them, which blocks the entry of any sounds. 

Therefore, how effective it is, depends on the thickness of the glass you choose. The most important task here is to install the glass on top so that it holds tightly and does not form a draft. This way, you can significantly increase soundproofing. 

Summary

As you can see, there are many options for soundproofing windows, and you can choose the most suitable one. Window noise insulation in the apartment, carried out by all the rules, will help make your home quiet and cozy. In addition, you can make your room warmer. The main thing is to block every window from your home to avoid annoying noises to get an effective result.

FAQ

What is the cheapest way to soundproof a window?

The cheapest option is window foam. With this, you can foam all the gaps around your window, thereby controlling the noise coming into your room from the outside. But you should know that it does not entirely block sounds, only minor ones.

Does a thicker window glass reduce noise?

Yes, of course. The thicker your glass, the less noise will pass through it. But each window has its frequency. And at specific frequencies, the window can give loud sounds even if thick. Therefore, it is better to use double glazing than one thick glass.

Why can I hear the wind through my window?

There can be many reasons for this. For example:
– poorly closed windows;
– gaps around the window;
– poor sealant;
– improperly installed windows.
So, it can cause the wind to enter your windows, creating an unpleasant whistling sound. Therefore, check your window for serviceability before making soundproofing.

Does acoustic foam block outside noise?

Most experts advise using laminated windows if you need good noise insulation. They can avoid 95% of all noise from the outside thanks to their material. Laminated windows have two layers of glass, between which there is an additional transparent layer of plastic, which acts as a soundproof.
