How Much Do Soundproof Windows Cost

If you live in a big city or another noisy area and find it hard to relax from all the noise, or if you work at home and are having trouble focusing due to the noise distractions constantly occurring, you have probably thought about soundproofing your windows.

This can be a great solution for keeping outside noise out or even inside noise in. But, How much do soundproof windows cost? Keep reading to find out.

How Much Do Soundproof Windows Cost?

Noises come from many things, such as construction, noisy vehicles, or even neighbors! If you are reading this, it is likely you have been having trouble with noises of some sort, and you need to find a solution.

It could also be that you are trying to find a way to keep your noise inside, like if you are a musician or have another occupation that can be quite loud.

Soundproof windows could be the answer to your problems, but they can be pretty expensive, with a price range of $300 to $1500 per window, and an average cost of $900. That is a good bit of money for the average person, but it may be worth it in your situation.

There are a few different factors that determine how much it will cost you to get soundproof windows, including the size of your window, how much noise you want to filter, and if you need an overall window replacement or want to just soundproof your existing window.

In this article, we will go over the most common factors to take into consideration when finding an average price, as well as some other ways you can soundproof your windows for less.

1. Size of your windows

The size of your windows plays a big part in how much it will cost to soundproof them. Not only will more oversized windows require more materials, but they will also have higher labor costs.

Smaller windows, around 18 x 24, will have a starting cost of around $200, while a large 44 x 52 will cost upward of $1800.

It is also important to keep in mind that if you are soundproofing extremely large custom windows, you may need a permit. So check with your local laws to see if one will be required for your project.

If you do need a permit, you are looking at around $50-$200 for each window.

2. Double-pane or Triple pane

When determining how much it will cost to soundproof your windows, the type of windows may be one of the biggest factors. Double-pane windows and triple-pane windows are made soundproof by adding a layer of a certain type of gas between the panes.

For double panes, there is gas between the two glass panes, and they cost between $350 and $850. Triple-pane windows have two layers of gas between the glass and cost between $450 and $3550 per window.

Triple-pane windows offer greater noise reduction than double panes because they use an additional layer of glass along with an additional layer of gas, which also contributes to the much higher price.

Alternatively, you can choose to use laminate glass instead of gas. Laminate double and triple-pane windows consist of a double or triple layer of glass with a plastic interlayer between them.

3. Type Of Gas

The type of gas between the glass can affect the price as well. Argon, krypton, and xenon are the gas options available, each offering a different level of sound reduction.

The cheapest of these is argon, the most expensive is xenon, and krypton is in the middle.

Argon is the cheapest because it is easier to find and if you only need light sound reduction, argon is likely your best option.

4. Type Of Frame

Type Of Frame

The type of window frame will matter slightly, but not as much as the other factors, and it is only essential if you are considering a wood frame.

Wood frames are a lot pricier than other frame materials, so if you have your heart set on a good frame, you will want to take this into consideration.

Other types of frames consist of vinyl and aluminum, which are relatively inexpensive and won’t cost much more to install.

5. Window Location

Another thing you don’t want to overlook when determining how much it will cost to replace a soundproof window is the location of the window.

Windows on the ground will end up costing far less than windows on an upper level. If you have windows that are extremely high up, you could be looking at a large extra expense.

6. Soundproofing existing windows

If you don’t want to replace your windows but want to soundproof your existing windows, window inserts are a great option.

These inserts are installed in front of the glass on the inside of the window, creating a sound barrier. These reduce noise by about 75% and only cost between $250 and $500 per window.

7. DIY or Professional

If you are replacing your windows with soundproof windows, you may be wondering if you need to hire a professional or if this is a project you can do yourself to eliminate labor costs.

While you can do it yourself, this probably isn’t the best option. While labor costs can cost up to $800 a window, it is worth the price to ensure it is done correctly.

You also need to consider that professionals already have the tools they need, while you would probably have to invest in tools you may never use again. Tools can be costly, and you may even end up paying just as much, if not more, than you would for labor costs.

If you need to have your windows replaced but are worried about the costs, some window installers offer to finance so you can make payments on your soundproof windows gradually.

If you decide to take on this project, I recommend having help and learning as much as you can about it first.

Whenever taking on a home improvement project, pay close attention to safety protocols and always wear glasses, an appropriate mask, and gloves when working with chemicals.

Cheaper Options

Cheaper Options

Noise pollution can be annoying, but you may not have to spend an arm and a leg to get some peace and quiet. Here are a few ideas you may want to try before investing in soundproofing your windows.

1. Curtains

Sound-dampening curtains are worth considering for light noise reduction without breaking the bank. These curtains absorb sound, which creates an overall quieter area.

Depending on the thickness, they tend to cost between $20 to $400 per curtain.

2. Foam Plugs

Foam plugs are boards that fit into your window frame and block sound. They are an extremely cost-effective alternative, with an average cost of$25 of $75 per window.

They are also practical if you just need a quick fix if the noise is not long-term, such as construction going on next door or a festival near your house.

You can simply put them in your frame when you need to reduce noise and remove them afterward.

3. Shutters


Soundproof shutters are another great option to consider. They cost between $70 to $350 per window.

4. Caulk

Sometimes excess noise can be caused by our windows not being insulated properly. You can use caulk to seal your windows better, which will help with sound. They also make acoustic caulk which is specifically designed to reduce noise transmission.

5. Foam Tape

Foam tape works similarly to caulk but is less messy, and it’s not permanent. It is self-adhesive and can easily be applied around your windows between your window and the frame.

6. Mass Loaded Vinyl

If you don’t use your window for light or airflow and keep it covered anyway, then mass-loaded vinyl may be worth looking into. Mass-loaded vinyl is a combination of both vinyl and PVC and is effective in blocking sound from vibrations.

It isn’t very effective in reducing things like traffic noise, so if that is your issue, this probably isn’t the right fix. However, It is fairly inexpensive and can be paired with sound-dampening curtains, so it may be worth a try either way.


Airports, construction, and highways, among other things, can prove to be a nuisance for homeowners, and soundproofing your windows may be your best option.
