Living in the city, noise pollution is almost impossible to avoid. However, we cannot ignore it because it can cause serious health problems. When you constantly must endure noise of more than 50dB (decibels), you start to feel tired. It becomes difficult to concentrate, you can develop digestive disorders, vascular diseases, hearing impairment and other diseases. The recommended maximum LAeq (Equivalent Continuous Sound Pressure) level for noises in the home – in living rooms and bedrooms for example – is between 30dB and 34dB. Therefore, sound-absorbing windows are particularly important in buildings located in the city, near airports, railways, or busy streets. Soundproof windows will cost slightly more than standard double glazing, however, if you have noise entering your home then they are an excellent investment for your well-being and comfort.

As sound waves travel through the air and varied materials, the waves can be minimized. Where the problem of noise is especially relevant, the choice of glass can be very important in helping to reduce noise levels and meet noise requirements. The highest noise insulation is achieved using acoustic laminated glass, sometimes known as soundproof glass. Acoustic glass is made by laminating two pieces of glass together with a sound-blocking PVB (Polyvinyl Butyral) film. PVB provides excellent acoustic performance by dampening sound waves and stopping the vibrations from passing through the glass. Because acoustic glass is laminated glass, it also gives the advantage of safety. If for some reason the acoustic glass window does break, the glass pieces do not fall out due to the PVB layer in the laminated glass holding the whole structure together.

Noise-reducing performance of acoustic windows can be achieved through a variety of combinations:

  1. Glass pane thicknesses – the thicker the glass, the better its noise reduction properties.
  2. Interlayers – laminated glass which consists of a special PVB interlayer sandwiched between two glass panes. All these together block noise from entering homes through the window.
  3. Distances between panes – the larger the gap between the panes of glass the better acoustic performance of soundproof glazing.

Acoustic glass can also improve the thermal properties of your home. This is great for reducing energy bills as the thick glass keeps more heat and it is ideal for keeping the property warm during the winter. In case of fire, the plastic interlayer is not degraded, so laminated glass provides better protection from fire rather than standard glass.

Triple glazing has similar benefits as acoustic glass. If noise reduction is a main priority, then acoustic glass is best, but if thermal efficiency is more important – then triple glazing would be the choice.

If you are in conservation areas installing soundproof windows becomes a little trickier. These areas prevent you from making serious alterations to the property that might affect its historical value. Each local authority will determine its standards, and it is always better to speak to the Local Planning Authority. Most of the time conservation areas allow upgrades to soundproof windows if the new frames are the same style, design, and material as the old windows. However, if acoustic glass is not approved you could also consider changing the seals on your existing windows if they are in poor condition.

It is important to remember that sound-reducing windows will never be 100% soundproof due to building regulations and the need for good ventilation in the home. When windows and doors are replaced, ventilation must be considered. One more thing to have in mind is that not all exterior noise can be avoided. It is not just gaps around the windows and doors that can let in more sound – it is also walls and roof, ventilator duck, air brick, trickle vents and chimney where sound can enter. It also enters through the small gaps or can come through floors, solid walls, ceilings and window panes. However, there are several factors that can help you control the noise in your home through design and layout, as well as a combination of other factors:

  1. You can block some of the noise from the next door by rearranging your furniture against the neighbour’s wall.
  2. Rugs are a great option for blocking some noise. The right rug can tie a room together, and provide a soft, warm refuge for your feet.
  3. Curtains or shutters also can have sound-reducing effects.
  4. Hedges or fence in front of the window – a hedge/fence naturally slows down wind as it passes through its open structure, calming the feel of the wind on the other side.
