Keeping unwanted noise where it belongs – outside

With over 95% of us valuing a good night’s sleep, we understand how detrimental outside noise can be to us achieving it. In fact, our independent research in April 2018, revealed that we are kept awake one night a week by noise or disturbances outside our homes. Whether it’s the constant hum of traffic keeping you awake at night or the neighbour’s extra loud band practice spoiling the enjoyment of your favourite TV show, Everest Acoustic double and triple glazing will be music to your ears.

A cosy bedroom which benefits from the soundproofing of acoustic glass

Everest acoustic windows have been approved by the international Quiet Mark award programme

An accreditation that's definitely worth shouting about

Everest is the only home improvement window company whose windows have been approved by the international Quiet Mark award programme. Our excellent quality speaks volumes, but the unique Quiet Mark accreditation on our Acoustic windows, which is only given to companies who are dedicated to noise reduction, is definitely worth shouting about.

Taking soundproofing to a new level

Everest's new laminated Acoustic glass has a special polymer layer sandwiched between the panes of glass, specifically engineered to disrupt and absorb sound waves and reduce noise pollution.

In general, using a combination of laminated glass and different thicknesses of glass reduces vibrations and noise, so less sound travels through the window. In tests, our Acoustic double glazed windows reduce sound by up to 40dB, which would take the loud 80dB noise from road traffic down to a quiet 40dB noise. The equivalent to the sound of someone speaking in a library.

Put another way, noise reduction can also be expressed in terms of distance. Every 3dB reduction in noise doubles the distance. The Everest Double Glazed window reduces sound by 33dB, but the Acoustic option reduces noise by 40dB. This further 7dB means that if a road was 20 metres from your house, with Acoustic glazing it will make the sound appear as if the road is 80 metres away – that’s a whole four times further.

Of course, we have also created our new Acoustic double and triple glazing to be pleasing on the eye, as well as the ear, making the Low E coating super thin. In fact, on 4mm glass it is only 40 microns thick.

FAQs

Choosing new windows can be a daunting task, so to help you here are some popular FAQs which you might find useful.

+
What is acoustic glass?
Acoustic glass is made up of 2 panes of 3mm glass with a 3 ply (PVB) interlayer sandwiched inbetween them. This interlayer has a special noise dampening core which helps to reduce vibration so less sound travels through the window.
+
How does acoustic double glazing work?
Acoustic double glazing works by using a combination of laminated glass and different thickness of glass to help reduce vibrations and noise, so less sound travels through the window. In tests, Everest Acoustic double glazed windows reduced sound by up to 40dB, which would take a loud 80dB noise from a busy road to a quiet 40dB.
+
Can you make windows soundproof?
If you live in a built up area, prone to noise pollution, then replacing your windows with double glazing may be the answer to your soundproofing needs. The extra panes of glass from a double glazed window unit can assist in reducing outside noise, especially if you are upgrading from ill-fitting single glazed windows. When choosing your windows think about having thicker glass, the gap between the panes of glass and, if noise is a significant issue, perhaps consider laminated glass. At Everest, we offer Acoustic glass on our double glazing, containing a special polymer layer engineered to absorb sound waves and noise pollution.

What are Glass Options for Windows?
With so many glass options for windows, it is important to understand which would be best suited for your requirements. Low E glass is a great all round option for energy efficiency. Low Iron glass offers high clarity and energy efficiency, and as such using this kind of glass will allow more of the sun’s energy and heat into your home. Toughened glass, five times stronger than regular glass, is often used for preparing balcony doors and windows. Laminated glass, contains a plastic interlayer offering better insulation and resistance against damage, and as such is often us on ground floor windows and doors. Laminated glass also cuts out UV rays reducing the bleaching effects of the sun on furniture and fabrics.
+
Which glass is best for double glazing?
Typically, glass used in double glazing is selected due to its thermal efficiencies. The best glass for double glazing would be Low-E (or low emissivity). Made with a microscopically thin, transparent layer, it reflects long wave infrared energy for heat. Strategically placed on the inner pane of glass with the purpose to maintain a comfortable temperature and help keep heat indoors.
+
What is between the glass in double glazing?
The most effective double glazing is comprised of two panes of glass, separated by a spacer bar and seals to create an air tight environment. Argon, a dense, non-toxic gas, fills the gap within double glazing to keep your home warm, acting as a barrier when heat is attempting to pass through the layers of glass.
