New Breakthrough in Acoustic Double-Glazing

    Acoustic Double-Glazing

    Acoustic glass windows are becoming more and more sophisticated, and in recent releases from window manufacturers there has been a breakthrough in standard. The future promises better sound insulation in our homes, thanks to acoustic, sound wave absorbing technology.

    The latest acoustic double-glazed glass windows are designed slightly differently; the acoustic interlayer used is made of a special polymer, which yields even higher rates of sound waves absorption. When tested, windows with this new acoustic polymer interlayer were able to reduce noise by a much greater average of 40 decibels.

    Noise pollution is a common problem in urban areas, so these latest developments give us more effective strategies for noise dampening and reduction. Prolonged exposure to noise pollution can lead to significant disturbance and stress. An example would be the low-level commotion caused by outside traffic, which is around 70 decibels, but can still have negative effects in the long term after continuous exposure.

    As such, acoustic windows and panels is an area that is developing at an alarming rate. There has been a lot of research conducted by manufacturers in the best ways to optimise acoustic absorption, and these latest products have some of the most effective noise reduction features to date. Traditional laminated acoustic glass windows have been tested to reduce noise by around 33 to 35 decibels.

    Usually, these laminated acoustic windows are constructed of two or more sheets of glass, and acoustic interlayers between them which hold the glass together. The interlayers weaken any sound waves passing through, and function to dampen the incoming noise. The sheets of glass will vary in thickness most of the time to increase its insulating properties.

    Some might assume that a 7 decibel difference isn’t significant, but Martin Troughton, Marketing Director for Everest Home Improvements, explains: “Noise reduction can be expressed in terms of distance when it comes to our perception, to give it some context. Each 3dB reduction in noise effectively doubles the distance, or halves our perception of the sound.”

    Everest is one acoustic window manufacturer utilising some of the latest groundbreaking acoustic insulation technology, pioneering the polymer acoustic interlayer design. Their new range is on sale as of May 2018. When explaining the effectiveness of the newest range of acoustic laminate windows, Troughton gives the following example: “If you have a noisy road 20 metres from your house, fitting Everest acoustic double glazed windows will give the impression of pushing that road 80 metres away. This makes a huge difference not only to the noise pollution levels within our home, but also to our general health and wellbeing.”

    In addition to Everest’s release, Print Acoustics are introducing a new range of 14 different acoustic, sound wave absorbing panels. Their latest collection was announced on the 30th April 2018, and shows that acoustic windows are not the only invention utilising this technology to combat and reduce noise. Division manager for Print Acoustics, Kristoff Ver Eecke, describes the function of these panels: “Our collection of acoustic absorbing panels is developed to absorb and reduce all kinds of disturbing noises in an area, leading to an increased acoustic comfort, even in rooms with large audiences and a lot of ambient noise, such as auditoriums, meeting rooms and offices, but also in hospitals and retirement homes, schools, sports facilities, bars, restaurants, hotels.”

    Domestic comfort and protection from outside noise is looking to be prevalent in the future, and the latest strides in the acoustic sound absorption and acoustic window industries show the best results in sound reduction to date. Before long, specifically-engineered acoustic products will likely appear in most residencies, offices and other buildings.
