Double Glazing: A Guide to Acoustic Performance

   Double Glazing: A Guide to Acoustic Performance

At Ecostar, we believe that double glazing is a superior choice compared to single glazing. It has many benefits attached to your home, including letting in floods of natural light and keeping your home warmer. But as well as being a strong insulator of heat, it is also a good insulator of sound. In this guide, we will talk about how double glazing will help improve your home.

It will significantly affect your thermal and acoustic performance because when the noise vibration hits a single glazed window, the pane vibrates and travels straight to your ears. In comparison, when you install double glazing in your windows, thicker panels are put into place, making noise easier.

Another advantage that double glazing can provide to your home’s acoustics is that when it is fitted, there aren’t any gaps around the windows to let the noise through. The panes on your double glazing don’t make any contact, dampening the sound waves. Double glazing can reduce the noise in your home by around 31 decibels. 

Double glazing can boost acoustic performance because the larger the gap is on one side, the easier it will be to absorb the sound. You can bolster the sound using 6.4mm laminate glass outside the window. This is more secure because it houses 6.4m Perspex sheets used in car windows.   

Another way to treat the outside noise coming into your home is by using acoustic glass in your home. Acoustic glass is very important because it is best for motorway, airport, or train line properties. It is useful in tough weather conditions because the sound of the rain is also greatly reduced.  

When acoustic glass is installed, the outside noise can be reduced. This is made from two acoustic interlayers with a special resin installed, which isn’t noticeable when looking at the glass. The layers are crafted from PVB (polyvinyl butyral), creating a strong bond within the glazed unit. This significantly improves your home because it will be quieter and more peaceful. 

 Whatever style you go for, acoustic glass is suitable for both modern and contemporary homes, so we have plenty of designs that are right for you. There are different grades of resin which will treat unwanted sound. Low maintenance means you don’t have to compromise your home’s kerb appeal.  

When installing acoustic glass on your property, it is important to consider a few things. One of the most important aspects is the window’s performance, for instance, in tough conditions. 

You can also consider laminated glass to insulate your home better. Similar to acoustic glass, laminated glass has separate layers, which reduces noise by tweaking the thickness of the glass and creating more space between the glass panes. This will help absorb the sound that travels through, which is ideal if you want to reduce the impact of the noise outside.  

Acoustic glass can be enhanced by installing specialist noise reduction glass and installing the PVB laminate. This structure is effective in dampening sound and significantly reducing sound pollution. 

Triple glazing will also help reduce the sound significantly. Triple glazing is similar to double glazing. However, it adds an extra layer of glazing that will boost your home’s acoustic performance while also supporting laminate glass for extra insulation. This will help reduce quiet sounds to a whisper.  

When it comes to measuring sound, plenty of other factors other than glass come into play. A noise reduction spectrum ranges from 36 – 52 dB for double glazing and even goes up to 54dB for triple glazing. The calculations mean that when 10dB is observed, this reduces the noise by 50%, while 40dB will result in a 94% drop, demonstrating how effective double glazing and triple glazing are in your home. 

We hope that this article has helped you understand how double and triple glazing enhances your home’s acoustic performance. With the addition of laminated or acoustic glass, you will enjoy a home that is peaceful and tranquil.
