There are many double glazing companies around with overly enthusiastic sales people who will sell you a dream of quietude and peace, yet this isn’t an altogether realistic dream. Most statistics used such as ‘reduce noise by 50%’ are based on laboratory tests that cannot replicate the reality of the modern world. Depending on your needs and expectations, the gap between what you think are getting, and what you actually get can be worlds apart. The many variables such as location, material of your property, proximity to potential sources of noise and even the roof structure can impact so widely that its often impossible to make such claims without seeing the destination property first.
How much noise can you actually reduce?
There are many solutions to reducing noise within your property, the main one being the windows as this is where the structure of most properties is at its thinnest. It is worth taking some time at this point to work out your expectations about what life will be like after installation of acoustic glass. If your main motivating factor was to cut out the drone of heavy traffic outside, then acoustic glass will work well and cut out a significant proportion of the sound and life will be quieter. If you are expecting to never hear a single peep from the traffic ever again, then sadly this won’t be the case.
Another factor to consider is whether you need the acoustic glass for professional purposes. If you work from home, have a home office, take calls or need silence in order to concentrate, then acoustic glass as part of creating a quiet space can work really well. The structure of acoustic glass is a careful layering of two panes of high-quality float glass (the same used in our standard Double Glazed Units), which are then sandwiched together with a membrane to form a composite pane.
This effectively creates a barrier between the inside and the outside, due to the construction and thickness of the glass. Due to sound having different wave lengths, different thicknesses of glass are more effective at reducing certain frequencies of sound. The composite used in our acoustic glass disrupts the sound waves and reduces incoming sound to a much more bearable level, so in either a work or home environment you should notice a difference.
Acoustic glass or double glazing?
The big question however concerns the choice between double glazing and acoustic glass – is there really a difference overall? The short answer is yes, due to the above-mentioned layering technique. The main function of acoustic glass is to disrupt sound waves, whereas double glazing – although an excellent sound barrier in itself – isn’t as robust at disrupting sound as the panes are usually both the same thickness. The real question is how much quiet you really need!
