Noise Reduction Windows for Busy Roads

July 11th, 2018

One of the most common complaints we get from our clients is that they’ve moved into a beautiful new property only to discover that there’s an indefatigable swathe of night buses that trundle their street keeping them up at night. If you’re one of those sufferers, we understand your pain. Losing out on shut-eye due to the N35 really isn’t something to be envied.

So what are your options?

Well, I am sure you have heard of all the classics – the coatings you can put on the glass, the noise cancelling blinds, the secondary glazing. All of which will offer a degree of difference and turn the chugging bus into a, well, slightly less loud chugging bus, but they won’t get rid of the problem completely. I find it best to put numbers to things, so here are numbers:

  • 70-80dB is the average noise level of a busy road at daytime
  • secondary glazing offers a reduction in noise pollution of 12dB
  • the ‘acceptable’ for a living room or bedroom is 30-35dB

Therefore, with secondary glazing, the best you can hope for is a noise level of 58dB in your living room – still way over what is deemed to be the tolerable level. The other options offer far less. This will certainly be a noticeable effect, but these solutions raise other questions, such as – do you want to lose all your sill space? Will you be satisfied with a slightly ‘less loud’ home?

If the answer is a resounding ‘no!’, then you have found the right guys. We specialise in manufacturing and installing windows that deal specifically with the root of the problem and don’t just offer stop-gap solutions. Whilst this might sound like we re-route the buses around your house, we can’t actually do that and would get in a lot of trouble if we tried.

Instead, what we do is manufacture window solutions that work best for particular noise complaints – we have a range that is specifically designed to deal with the low rumble of busy roads and a different range for the roar of planes. It’s all about understanding how the sound waves work and using specific thicknesses of glass and designs of the frame in order to best combat each kind of noise pollution.

In most cases, where we can employ our designs, this can offer a reduction of 40-45dB, turning the average daytime jungle run of the city’s streets into the ambient hum of the countryside. At night, the change is incredibly dramatic!
