How To Soundproof Windows And Doors

If you find yourself in a position where you can’t tolerate the sound of road traffic, rail noise, noisy neighbours, or other sounds associated with a busy and lively street, and moving is not an option at the moment, then soundproofing your doors and windows may be the only way to find some peace and quiet.

 Soundproof Windows And Doors

Most window and door manufacturers today offer custom products with enhanced sound insulation for new and replacement applications. All windows and framed doors offer a certain degree of soundproofing, but whether the level of sound control is adequate or not depends on various factors including:

  • Glazing,

  • Volume of gas between glass panes,

  • Rubber seals,

  • Frame construction,

  • Proper installation.

Unfortunately, any failure in one of these design factors automatically results in the failure of the soundproof barrier to deliver sound control to the desired specification.

  1. Glazing

    Glazing used in windows is quite thin and ineffective as a soundproof barrier. But for improved thermal efficiency, insulation, and sound reduction, manufacturers offer glazing with two or more sheets of glass.

    For custom-made windows, the thickness and amount of glazing used depends on the extent of noise reduction desired, as well as the origin of the sound. In addition, each glass pane in a soundproof window or door features a polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) coating that forms a strong hydrocarbon bond with the glazing unit.

    The lamination helps to improve noise reduction by decreasing the elasticity of the glass and providing another layer of noise dampening. It also dramatically increases the strength of the glazing for extra security.

  2. Volume of Gas Between the Panes

    Double and triple glazed windows usually contain gas sealed in between them for improved thermal efficiency and noise reduction. If a glass pane vibrates due to sound, it causes the gas within the volume to compress and transmit the vibration to the other pane. The smaller the volume of gas, the greater the compression applied to the gas and the vibration transmitted to the second glass pane.

    Increasing the gap means more gas volume, less compression, and less transmission of sound between the panes. Ideally, air leakage through a soundproof window or framed door should be zero for optimal thermal efficiency and sound attenuation. However, most designs specify 0.1% to 0.3% air leakage, which though negligible, is necessary for minimal air exchange, to allay health concerns.

  3. Final Note

    The amount of window glazing and volume of gas between the panes are two of the most important factors for noise reduction in window and door installations. But it is just as important to use the right seals to reduce gas leakage, choose the right frame material, and ensure proper installation, for optimal performance.

Do Soundproof Windows Work?

With cities growing every day, the same is also true of noise pollution. In fact, our towns and cities are expected to get much louder due to the growth of our population as well as due to urbanization. From construction to lawnmowers, this noise is not only a nuisance but it can also negatively impact our health. Recent studies have been showing a link between noise and increased levels of stress, anxiety, poor sleep and cardiovascular disease.

Do Soundproof Windows Work?

Soundproof windows offer protection against the intrusive noises of the outside world. They are touted as being particularly ideal for families with small children and are especially popular in busy cities where buses, ambulances and police typically drive by. They are also popular in homes that are near highways.With so many products on the market these days, do soundproof windows actually work or are they simply another fad?

Do Soundproof Windows Work?

It is more accurate to say that soundproof windows are actually sound reducing windows. However, they will block out 90 to 95 per cent of sound coming in. In this way, soundproof windows do work. Sound is reduced because the glass is thicker, more distance is added between the window panes and laminated glass is used.

It is also important to remember that soundproof windows are better at blocking out certain sounds than others. Sounds with low frequencies are more difficult to block out than sounds with high frequencies, such as chirping birds. However, soundproof windows are still very effective.

How to Find the Best Soundproof Windows

Keep in mind that some soundproof windows will be better than others. You will be able to choose a higher quality soundproof window by looking at the industry rating that measures how well it blocks out sound. You will find this information by looking at the sound transmission class (STC) scale. A higher number will yield a window that is better at reducing noise.

In summary, soundproof windows are the only way to permanently reduce the noise level in your home, despite the many quick fixes on the market.
