How much do soundproof windows cost?

Soundproof windows can vary in cost depending on various factors. On average, the cost of soundproof windows can range from $300 to $2,000 per window, including both materials and installation.

However, it’s important to note that this is just an average figure and prices can be higher or lower depending on specific requirements and preferences.

Factors affecting the cost of a soundproof window

When it comes to soundproof windows, there are several factors that affect how much they cost. Let’s break it down:

1. Size of the window

I no need to tell you that the size of a soundproof window affects how much it costs. If the window is big, it needs more stuff like materials and work to make it. That’s why bigger windows can be more expensive.

And here’s the thing – larger windows might need special planning and design to keep the noise out really well. That special engineering can also add to the total cost of the window.

2. Type of soundproofing materials used

The choice of soundproofing materials significantly impacts the cost of the window.  Different materials offer varying levels of sound insulation, durability, and energy efficiency.

Some super cool windows have multiple layers of glass, or they use something called laminated glass or acoustic-grade glazing.

These things are excellent at keeping the noise outside. But guess what? They can be more expensive than standard single-pane windows.

3. Brand reputation

You know what? The brand and quality of soundproof windows play a crucial role in determining its cost. Some brands are really famous and trusted.

They spend time and money on research and invent new ways to keep the noise away.

Those high-quality windows are like superheroes – they’re super strong, last a long time, and do an amazing job at stopping noise. And because they’re so good, they will obviously be more expensive.

By the way, I do let you know that CitiQuiet is one of the reputable brand in the field of soundproof window and CitiQuiet windows costs anywhere between $400 to up to $2000+.

4. Acoustic Performance Rating:

Soundproof windows have special ratings like Sound Transmission Class (STC) or Outdoor-Indoor Transmission Class (OITC). These ratings tell us how good the window is at stopping noise from getting inside our homes.

The higher the rating, the better the window is at keeping things nice and quiet inside. Isn’t that awesome?

But to get those high ratings, these windows use really smart and advanced soundproofing technologies. Because of all that cool technology, these windows cost more than regular ones.

5. Additional features

Soundproof windows can come with cool features that make them even better. 

For example, some have blinds built right into them, so you can control how much light comes in.

And that’s not all! Some windows have special coatings that keep your home cozy and protect you from the sun’s rays (that’s UV protection!). It’s like having a shield against the sun!

But all these fantastic features can make the window cost a bit more. 

Different Types of Soundproof Windows and their price range

Soundproof Window TypeDescriptionPrice Range
Single-pane soundproofOne layer of glass, better at blocking noise than standard single-pane windows.$200 to $600 per window
Double-pane soundproofTwo layers of glass with air or insulating gas, providing improved noise reduction.$300 to $1,500 per window
Triple-pane soundproofThree layers of glass with insulating gas, offering superior sound insulation.$700 to $2,500 per window
Acoustic laminated glassSpecially designed with multiple glass layers bonded with sound-reducing material.$1,000 to $3,500 per window

1. Single-pane soundproof windows

Let’s first talk about single-pane soundproof windows. These windows have only one layer of glass, which helps reduce some noise, but not as much as the fancier ones.

Compared to regular single-pane windows, they’re better at blocking noise, which is pretty cool!

And these windows are usually on the cheaper side, so they won’t break the piggy bank. The price can be anywhere from $200 to $600 per window, depending on how big the window is.

2. Double-pane soundproof windows

Double-pane soundproof windows feature two layers of glass separated by a space filled with air or insulating gas, such as argon or krypton. 

The trapped air or gas acts as an additional sound barrier, improving the window’s noise reduction properties.

Well, these types of windows can be to soundproof almost all the windows, but in my perspective, they are best soundproofing old windows, noisy window, and for Velux window noise insulating.

The price range for double-pane soundproof windows is generally higher than single-pane windows, averaging between $300 to $1,500 per window, depending on size, brand, and additional features.

3. Triple-pane soundproof windows

Triple-pane soundproof windows take noise reduction a step further by incorporating three layers of glass separated by insulating gas. 

The additional glass layer provides superior sound insulation, making them highly effective in blocking external noise. 

However, the extra glass and gas increase manufacturing costs, resulting in a higher price range. The cost of triple-pane soundproof windows typically ranges from $700 to $2,500 per window.

4. Acoustic laminated glass windows

These windows are specially designed to block noise. They are made by bonding two or more glass layers together with a special material in between, usually made of polyvinyl butyral (PVB).

This special material helps to reduce sound, making the windows great at keeping unwanted noise out.

However, because of their advanced soundproofing technology, these windows tend to be more expensive compared to other options.

The price of these windows usually starts at $1,000 and can go up to $3,500 per window, depending on the size, and any extra features you might want.

Installation costs of a soundproof window

The installation of soundproof windows can be approached in two ways: Do-It-Yourself (DIY) or Professional Installation.

DIY Installation:

DIY installation means homeowners taking on the task of installing soundproof windows themselves. This option might save money initially, but let me tell you that it requires a certain level of skill and expertise. 

DIY installation may save on labor costs, but it carries the risk of potential mistakes and may not provide the same level of soundproofing effectiveness.

So, DIY installation is better for people who have experience with windows or who are really confident in their handyman skills. If you’re not that confident, it will be best to hand it over to a pro.

Professional Installation:

Professional installation, on the other hand, involves hiring experienced technicians or window contractors to handle the installation process. 

Opting for professional installation ensures that the soundproof windows are properly installed, maximizing their noise reduction capabilities and ensuring long-term durability.

The average professional installation fees for soundproof windows can range from $100 to $300 per window.

This cost may be higher for larger or specialized windows that require additional labor or custom modifications.

Benefits of Soundproof Window

Well, first, let me tell you that soundproof windows offer several benefits than just noise reduction. 

Here are some benefits that soundproof windows provide.

  • They Reduce Noise: These special windows are made to stop outside noises from coming inside your home. They have multiple glass layers and something cool called an acoustic interlayer that absorbs and weakens sounds. 
  • They Save Energy: Soundproof windows often have superior insulating properties compared to standard windows. The multiple glass layers and acoustic interlayer contribute to better thermal insulation, reducing heat transfer between the indoor and outdoor environments. That means you can save energy and money on heating and cooling!
  • They Keep Things Private: With soundproof windows, what happens inside stays inside! They keep your conversations and sounds from going outside. This is particularly beneficial for buildings located in busy or densely populated areas.
  • They Protect Your Stuff: Many soundproof windows also come with a built-in UV filter that helps block harmful ultraviolet (UV) radiation from the sun. That keeps your furniture, carpets, and other stuff safe from fading or damage caused by the sun.
  • They’re Super Strong: These windows are built tough with many layers, making them strong and hard to break.

Which type of soundproof windows is the best?

Determining the best soundproof windows involves considering various factors, and there’s no one-size-fits-all solution.

Different types of soundproof windows offer varying levels of effectiveness based on their construction and materials.

Here are some options that are best in my perspective:

  • Double-Pane Soundproof Windows: These windows have two layers of glass with an air gap in between. The wider the air gap, the better the noise reduction. They are affordable and provide reasonable sound insulation for many settings.
  • Triple-Pane Soundproof Windows: With three layers of glass and two air gaps, triple-pane windows offer superior soundproofing. They are suitable for locations with high noise pollution or where excellent sound reduction is needed.
  • Laminated Glass Soundproof Windows: Laminated glass windows have multiple layers bonded together with an acoustic interlayer. They absorb and dampen sound effectively, offering exceptional noise reduction along with UV protection.
  • Acoustic Retrofit Soundproof Windows: These windows fit over existing ones, providing an extra soundproofing layer. They are ideal for soundproofing when complete window replacement is not possible or not budget-friendly. Their effectiveness may vary depending on the original window’s quality.

In the end, choosing the best soundproof windows depends on your specific needs, budget, and the level of noise reduction required.

How much noise a soundproof window can reduce?

The amount of noise reduction that a soundproof window can achieve is measured using a unit called Sound Transmission Class (STC). STC is a standard rating system used to quantify a material’s or window’s ability to reduce sound transmission.

Generally, soundproof windows with higher STC ratings offer greater noise reduction capabilities. A typical single-pane window may have an STC rating of around 25 to 30, while standard double-pane windows might have an STC rating of approximately 28 to 35.

However, high-quality soundproof windows with advanced construction and specialized soundproofing materials can achieve significantly higher STC ratings. These advanced windows may have STC ratings ranging from 40 to 55 or even higher.

For every increase of 10 points in the STC rating, the soundproof window can provide an approximate 50% reduction in sound transmission. So, a window with an STC rating of 40 can reduce noise by about 50% compared to a window with an STC rating of 30.

It’s important to note that the actual noise reduction achieved by a soundproof window can also depend on other factors such as the specific frequency of the noise, the overall acoustic design of the room, and any potential weak points in the soundproofing installation.

Alternative Ways To Soundproof a Window Cheaply

Soundproof Window Inserts$100 to $500 per windowCustom-made, long-term solution offering effective soundproofing.

1: Applying weatherstripping

Weatherstripping involves applying materials, such as foam or rubber strips, around the window frames to create an airtight seal.

This reduces sound transmission by preventing air leaks and vibrations that can carry sound. Weatherstripping is a cost-effective solution for enhancing the soundproofing of existing windows. 

2: Hang acoustic curtains or drapes

Acoustic curtains or thick, heavy drapes are designed with sound-absorbing materials that help dampen sound waves passing through the window.

The materials used in these curtains include dense fabrics, such as velvet or suede, along with layers of sound-absorbing fillers. 

In my view, acoustic curtains or drapes are best for sound blocking in bay windows and for noise reduction in a rental window and even they are best for soundproof a window in an apartment.

3: Attach soundproof window films

Soundproof window films are thin adhesive sheets applied to the glass surface. These films often incorporate sound-damping materials, such as polyethylene or vinyl, which help attenuate sound vibrations passing through the window.

Soundproof window films are relatively affordable compared to other soundproofing options and can be a DIY project. 

It is good option for noise reduction in a sliding window and for sash window soundproofing.

4: Sealing cracks and gaps around the window

Sealing cracks and gaps in window frames is a simple yet effective method for reducing sound leakage.

The cost of this approach is minimal, as it primarily involves purchasing caulk or sealant.

Properly sealing cracks and gaps can have a noticeable impact on sound insulation and also helps in improving energy efficiency by preventing drafts.

5: Install soundproof window inserts

In my opinion, it is one of the best alternatives to soundproof windows. Soundproof window inserts are custom-made panels designed to fit inside the window frame.

These inserts create an additional sound barrier, enhancing sound insulation by blocking sound transmission through the window.

They are perfect for noise reduction in a jalousie window and for acoustic treatment for a single-pane windows.
