Noise Reduction Windows

Make Your Home a Quieter Place to Be

  • Enhanced noise reducing windows
  • Made-to-measure, with a range of options
  • Market-leading energy-efficiency & security
  • Built to last with long-lasting guarantees

An increasing number of us want to reduce noise, so we can feel relaxed in the privacy of our own home. The good news is that we have solutions that can help to reduce the noise pollution in your home to make your home a more relaxing space.

Noise is both complex and personal and windows are certainly one factor that could help make your home a quieter, stress-free place to be and Everest have a range of options that could help.

We don't claim to eliminate all excessive external noise, but in many circumstances, our windows can help. How much difference you notice by installing Everest Noise Reducing Windows will be dependent on:

  • The state of your current windows
  • Where the noise is coming from
  • How the noise is leaking into your house
  • How sensitive you are to noise

What Are Noise Reduction Windows?

Noise reduction windows use specialist acoustic glass that reduces the amount of noise that is transmitted through the glass and window. Acoustic glass is a glazing unit that has a laminated pane of glass and the effect of the laminate is to disrupt the soundwaves and to help dampen sound.

Everest's noise-reduction windows feature our noise-reducing double glazing unit made of a 6mm Low Iron outer pane and 6.8mm acoustic laminated inner pane. These Everest windows have been approved by the international Quiet Mark award programme.

Everest noise reduction windows work by:

  • The thickness of the glass
  • Asymmetric thicknesses of glass to disrupt the soundwaves
  • Argon gas between the panes
  • Depth of gap between the panes
  • Sound-dampening laminate between panes

Everest Window Options to Reduce Noise

  • A difference - Everest Triple Glazing or Double Glazing with other types of glass
    As an entry-level solution, a well-fitted new window will reduce noise if it replaces a single or poor quality double glazed window. Other options to reduce noise include limiting the number of openers in the frame, high-quality seals and good installation. These will all make a difference to noise reduction. A standard Everest double or triple glazed window in comparison to an old and badly fitted window will help to noticeably reduce noise levels.

  • Noticeable difference - Everest Double Glazed Windows with Noise Reducing Glass
    The solution we most often recommend for reducing noise is our noise reducing double glazed window. The specialist glass works by having two different thicknesses of glass pane in the double glazed unit. 

  • Very good difference - Secondary Glazing for sound reduction
    Secondary glazing can also offer excellent results. This is because it can create a larger gap between the external pane and the internal pane creating a noise-reducing chamber. The more distance from the window pane to where your secondary glazing unit is installed the better. This can be a great alternative for older properties that have planning restrictions or rooms with access restrictions such as flats. However, secondary glazing is not suitable for all windows and the aesthetic can be off-putting for some.

Double and Triple Glazing Noise Reduction Compared

Everest Standard GlassEverest Noise Reducing Glass
Double Glazing⭐⭐⭐
A reasonable option if upgrading from single-glazed windows and you will notice a difference in noise reduction.
The best option we recommend if you have a well-insulated house that doesn't have sound leakage points.
Triple Glazing⭐⭐
This will make a difference if you have poor windows currently but is not recommended just for noise reduction.

How Effective Are Noise Reduction Windows?

How much you can reduce noise coming into your house depends on what you have now. If your home has old single glazed windows, you will notice a difference simply by adding new double glazing windows.

As described above, noise reduction also depends on how your home is constructed and the main entry point of the noise.

Sound is measured by the strength (amplitude) of the waves in decibels (dB)

*Everest Independent Testing

The table above is based on laboratory testing, where the glass is tested in isolation. In real life, there are other factors that might be leaking sound into your home, so we can only offer this as a guide and not a guarantee.

It's important to note that noise reduction windows will not make a room silent. They can make a considerable difference to the quality of life in your home, but we don't claim to make a home soundproof. And you may have to address other issues that are leaking sound into a room.

How Do Windows Let Noise into a Home?

The glass in your window is not the only element that can make a difference in how much the noise can be reduced.

The frame and the installation are just as important.

  • The seals that support the glass can cause sound leakage if they are faulty or degraded. If you have old double glazing, increased sound levels are an indication you need to change the seals or have a blown unit.
  • The number of opening sashes will make a difference.  Having one single pane of glass with no openers will deliver the highest reduction in noise, but this is frequently not practical for ventilation reasons.
  • Trickle vents built into the frame will allow noise to seep into the room even when the window is shut tight. These may be required by building regulations in certain situations.
  • The frame must be measured and fitted correctly to avoid any micro-gaps that can allow noise to leak into the room.

Is Your Home Suitable for Noise Reduction Windows?

Before choosing noise reduction glass and assessing if new windows can dial down the noise in your home, consider the following:

How is your home constructed?

If you have thin walls with minimal insulation, there is a chance sound is entering through the walls. Thicker construction, such as stone-built walls are less likely to be transmitting noise.

How many sound entry points do you have?

How many air bricks, trickle vents and fireplaces are there?

How many external doors do you have to the room?

Often overlooked, doorways are a considerable sound transmission point. Installing sound-reducing glass next to a front door is probably not going to make a noticeable difference.

What quality are your current windows?

Are your current windows single glazed, are there gaps or have the seals perished? Do you have a lot of opening sashes that are limiting the effectiveness of the window? The more problems with your current window, the more difference you will notice from new frames.

Commonly Asked Questions

  • +
    Can you soundproof windows?

    You can't fully soundproof a window. Soundproofing and noise-cancelling windows are misleading terms. There is no magic solution to 'soundproof' windows that can turn a residential house next to a noisy road, train line or airport into a silent space.

    There are ways to reduce noise, including installing Everest noise reduction glass that can make a significant difference in the amount of noise coming through a window. But, the glass in a residential window can never block out all noise pollution.

    It's not just the windows where sound can enter a room. Other entry points include chimneys, ventilation bricks and in old houses the general fabric of the building.

  • +
    What windows are best for soundproofing?

    You can achieve the best soundproofing through a combination of installing noise reducing glazing, planting hedges outside the window and installing wooden shutters or sound dampening curtains.

  • +
    Are triple glazed windows better than double glazing for soundproofing?

    It's widely considered that triple glazing is better for soundproofing than double glazing. But, this is a misconception. The most efficient way to reduce noise is to disrupt the soundwaves by using two different thicknesses of glass close together. Therefore, acoustic noise reducing glass is more effective at reducing noise than standard triple glazing.
