If you live in a city, noise pollution is impossible to avoid. Not only can it be annoying, but even dangerous to your health (more on this below), and this is when irritating noise becomes noise pollution.

Best Soundproof Windows

But by installing soundproof windows, or even just installing products that help to soundproof the windows you already have can make a big difference.

How do soundproof windows work? Basically, they reduce noise pollution by causing the sound wave to lose power and this is thanks to the materials they are made of that are designed to absorb and reflect sound.

These materials include acoustic glass and sealants that combat noise. 

But if you’re on a budget and can’t afford to install new soundproof windows don’t worry – there are other solutions. While these may not be as effective as replacing your windows they can reduce the effect noise pollution has on your life.

These methods include plugging up any air gaps in your window with acoustic caulk or weatherstripping, installing noise reduction curtains, blinds, or acoustic window inserts, or adding glazing/acrylic panels to your windows. 

Below we’ll take a look at different types of soundproof windows, as well as some products that can help you soundproof your existing windows.

Types of Noise Pollution

Noise pollution can take many forms depending on where you live, but there are some common noise pollution sources. We’ll take a look at three of the most common.

Aircraft noise pollution: Noise pollution caused by planes can range from a minor annoyance to a severe disturbance, depending on how close you are to a flightpath. If you live 1 mile below a flightpath the noise from planes can reach up to 97dB. 

Road traffic noise pollution: If you live in a city, this is the noise pollution you’re most likely to experience. The cacophony of cars, buses, and motorcycles can feel relentless day and night.

In most cases, noise pollution from the road will reach between 45-75dB. If you live in a suburban area, then you may experience the noise of traffic as a minor annoyance.

Rail or subway noise pollution: While living near a train or subway station can do wonders for your commute, the distinct rumble of the subway or the chug of freight trains can quickly take its toll.

At 100 feet away a diesel train will reach a maximum decibel level of about 80dB, which is the same noise a freight train makes from 15 feet away. Needless to say, prolonged exposure to this can have a negative affect on your hearing. 

Laminated Glass Windows

What makes laminated glass different from standard glass? Whereas standard glass simply consists of a single sheet laminated glass is two sheets of glass with an interlayer of plastic in between. This is usually poly vinyl butyral (PVB)

Laminated glass was invented by French chemist Edouard Benedictus in 1903. He came up with the idea when he dropped a glass flask that was wrapped in plastic cellulose nitrate and noticed that while the glass shattered, it didn’t break.

Glass engineers have been trying to perfect this ‘sandwiched glass’ ever since, giving us the laminated glass we know today.

This interlayer doesn’t just make the glass stronger, but it also acts as a place to embed other glass technologies to make further improvements to the glass, like making it fire resistant, or sound dampening! 

A sheet of laminated glass is far more effective at stopping sound waves than standard glass of the same size because the sound waves have a harder time travelling through the glass sheets and the PVB interlayer.

Just one pane of laminated glass within an insulated glass unit enhances the sound dampening qualities by several decibels. 

Dual And Triple-Pane Windows

When it comes to reducing the amount of noise in your home, you have several glass options. The most popular option is to upgrade your windows from a single-pane to a dual or triple-pane design.

A similar option is to choose a mixed millimeter glass design. When glass windows with different levels of thickness are paired up they help to dampen different sounds at different frequencies. 

The more glass panes are added to a window’s design, the less noise is able to travel through. Therefore, single-pane windows have the least amount of materials to slow down sound waves and they let more noise into your home.

Dual-pane windows (or double-pane windows) help to reduce some noise, but triple-pane windows are the best way to reduce the most noise.

Acoustic Glass Windows

Acoustic glass windows are an upgrade to laminated glass windows, and instead of having a layer of plastic in between sheets of glass, special acoustic glass windows are made with two sheets of glass with an acoustic resin layer sandwiched between them.

Acoustic glass also comes in a couple of different grades.

Some brands of acoustic glass windows have grades including CIP (this uses acoustic resin as the interlayer), PVB (this is acoustic grade PVB interlayer used in between PVB laminated glass), and EVA (laminated glass that uses ethylene vinyl acetate, or EVA as the interlayer).

EVA offers fantastic soundproofing properties and can also filter UV light. 

But while there are a few grades of acoustic glass, the difference between them – and even between laminated glass and acoustic glass – may not even be noticeable.

In fact, studies have shown that a difference of 3 decibels is barely perceptible by the human ear.

So unless there is a huge difference between one grade of acoustic glass and the next, you may not actually notice – or hear – the difference!

Frequently Asked Questions

What Is The Difference Between Secondary Glazing And Double Glazing?

Windows with double glazing are constructed using 2 sheets of glass with a gap between them. This is an isolated window that is installed on the outside of your property.

Meanwhile, secondary glazing is a glazing unit (that can be single or double glazed) that is installed within your existing frame and usually on the internal side of the sill.

Since there can be such a large gap between the external window and the secondary glazing, you’ll probably notice a dramatic difference in how much outside noise travels into your home.

But unless the noise pollution in your area is severe and unbearable, most people avoid installing secondary windows. This is because they don’t tend to look very nice, and it greatly reduces the amount of sill space you have.

How Do I Make A Room Soundproof? 

There are a lot of ways you can soundproof a room. What solution you choose to soundproof a room will depend on why you want to soundproof your room, and the layout of the room.

However, no matter why you need to soundproof your room, there are four key aspects to keep in mind. These are:

  • Adding mass
  • Dampening
  • Decoupling
  • Plugging gaps.

To stop sound escaping your room, mount all sound units on vibration insulation pads. Musicians swear by acoustic wedge panels to achieve this.

These are made out of polyurethane foam, and come with adhesive backs which make installing them by yourself a piece of cake.

No need to draft in a professional! However, if you’re renting your property you may want to check with your landlord if it’s okay to do this.

Sealing up vents will also stop sound seeping out of these cracks. But if this is done incorrectly it can cause a build up of damp.

How Should I Prepare For Installation Of Soundproof Windows?

If you’re having soundproof windows installed, the right preparation can prevent any accidents happening to your belongings or to your property itself, and cut down on installation time.

Before your installation, make sure to do the following:

  • Put items such as cameras, laptops, phones and jewellery in a safe place. 
  • Hide anything that can be removed, such as furniture and ornaments from the vicinity of the replacement area.
  • Remove picture frames, paintings and any other decorations from the walls.
  • Remove all blinds and curtains. 
  • If you have any alarm systems connected to your windows, temporarily disconnect them.

While most installation companies will remove and dispose of your old windows, double check they will do this before the installation.

Final Thoughts

As you can see, there are many ways to soundproof a room.

Soundproof windows are a great way to reduce noise pollution, while installing soundproof curtains and blankets on the walls and windows will also reduce the noise level by a few decibels.

However, if your walls are thick or insulated this can have a negative effect.

You can also construct independent soundproof stud walls using 75mm stud if possible. These would ideally be installed 25mm from your existing walls.

A suspended soundproof ceiling installed below your current ceiling can be mounted on hangers and can absorb noise coming from above.

Acoustic mineral wool is also an option, and can be installed between the joists in the floor with a heavy acoustic membrane (or soundproof mat) laid on the top.

A single 2mm layer can reduce noise by 24dB, and you can use as many layers as you like. 

You can also inspect the room for air gaps which let noise in and these can be filled in with materials like acoustical caulk. If you notice gaps around your windows you can also fill these in with foam gaskets.

When it comes to soundproofing, the options are endless!
