Advantages of acoustic DG over standard to reduce rail noise

HotShot2011

Hi,

A few months ago we moved into a house close to a busy rail line. This isn’t an issue in itself as we’ve lived very close to rail lines before and are not unduly bothered by the noise. However, given the chance to reduce it in the rear bedrooms, we might be tempted.

Therefore, as the existing double-glazing appears to be standard (I think 4 12 4) and is now well over ten years old, I was wondering if anyone has replaced standard DG with acoustic sound-reducing DG, and if so, what sort of difference there was? If the difference is appreciable, we may be willing to consider it, and it might be a good selling point when we move on in a few years.

There are quite a few threads on people going from single glazing to acoustic, but I can’t find much on more recent DG to acoustic. We would look to replace just the units rather than the whole window (frames are UPVC in good condition).

Any advice gratefully received

A single pane of secondary glazing 100mm in from the existing windows will work better than upgrading the units.

If you don’t want secondary then yes, change the units and go for a 6.4lam, 4mm float, 6mm tough. If you’ve got trickle vents then forget it as all the noise travels through them.

about 30 yrs ago I had a house with Everest secondary glazing, it was very good a reducing the noise of the kids playing in the street, much better than double glazing
problem was the dust that would get trapped between the outside (single glazing) and the secondary glazing units
if I lived in a noisey area I would look at having some form of secondary glazing
