double or tripple glazing

kay0

Hi everybody,

First post :j

I’m in the process of getting quotes for double glazing, I live under a flight path and by quite a busy road so one of my main specifications is noise reduction. A company has quoted me on triple glazing with 4-8-4-8-4 windows, my question is, as I was lead to believe sound reduction was better achieved via the air gap, are these windows better at reducing noise to a standard 4-20-4 window? Or should I try to find another company that manufacture deeper frames?

Thanks for your help.

My understanding of double glazing was, for sound reduction, the panes needed to be of different thicknesses.

Also, a principle to reduce sound is to increase mass. Laminated glass is far heavier than normal glass, so this would be worth considering.

I suggest that, ultimately, the weak point for sound penetration will be the pvcu frames, the quality of the weather stripping/draught seals and any trickle vents.

The ideal would be wooden frames and no vents. Hence you need to trade off Building Regulation matters and future maintenance of the frames.

Also consider good dense curtains for the windows.
