If you live on a busy road or have noisy neighbours, it can be really difficult to get a good night’s sleep. According to the World Health Organisation, traffic noise alone is harmful to the mental and physical wellbeing of almost a third of people living in Europe.
One of the main ways sound seeps into a room is through its windows. Luckily there are ways to soundproof your windows and get some peace and quiet even if you live in a noisy area.
1. Acoustic Glass
Acoustic glass is thicker than regular glass as it includes a soft plastic ‘interlayer’ through the centre which absorbs sound waves and significantly reduces the amount of noise that can pass through it.
Acoustic glazing can reduce the level of noise in a room by up to 10 decibels (dB). This may not sound much, but a 10dB reduction in sound means the level of noise is reduced by a massive 50% (see table below).
2. Draught proofing
Draught proofing your windows using compression seals instead of brush seals is another effective method of noise insulation. Compression seals are soft seals around a window that seal the gap between the window and the frame.
Getting your draught proofing right, as with acoustic glass, can reduce noise by a further 10 decibels, or 50%. So if you combine acoustic glass with compression seals on your windows, you can reduce traffic noise and the sound of noisy neighbours in your home by 75%.
