I wont go into to much details as my bloods boiling really lol.
short version:

The house i live in has 9" brick work so a lot thicker than a new build.
I have a Double glazed window already.
But the constant screaming and rowing in what used to be a quiet road
is taking it's tole after the last 4 or so years.
what i want to know is how much "more" would tripple glazing block out
unwanted noise?
Would i end up hearing more noise through the bricks than the window there for wasting my cash?
and yes eventualy we will move but that cant happen for an estimated 5 to 10 years.

help me out guys im going bonkers here, cheers.
 
Triple glazing won't block any more noise if the glass specification isn't right, I have 36db sound reduction triple glazed composite windows and can't hear a car go past (30 mph cul de sac) and have just installed 45db sound reduction to a site on a London red route and you just get a low drum.

However

Standard pvcu double glazed £100 - 150 sq m
Standard triple glazed composite windows £200 - 250 sq m
Additional sound reduction 36db - 45db triple glazed composite window £300 - 350 sq m

But it all goes out the window (excuse the pun) if you like fresh air and keep windows open or have non acoustic trickle vents.
 
Have you considered developing a serious meth addiction? Nothing says "I don't care about your noise, can you give me some money to buy more drugs, I'll cut you, you tart" more than a severe and crippling drug dependency.
 
Triple glazing, for when double is just too mainstream.

Triple glazing with proper thermal breaks is the easiest and cheapest way to get your CFSH points if you are Code 3 with Building Regs + 20% or Code 4 if you have 140mm Kingspan Kooltherm K3 insulation in the walls. So much heat is lost through windows, more efficient windows significantly reduce energy consumption.

So triple is becoming more mainstream.
 
Interesting topic for me, as I am in exactly the same situation. Not so much noisy neighbours but early morning noise. My house is 120 years old and also has thick as anything walls (though it is not a cavity wall) and the double glazing, apart from being double glazing, is crap.
 
All I'd say is, having just moved into a new flat meaning I've seen a bunch of places recently. The sound reduction from a secondary glazing can be outstanding.

A really crap flat, like absurdly awful, ground floor of grade 2 listed building without double glazing maybe 4 metres from a loud main road. We stepped inside and couldn't hear the road. All it had was fairly cheap and poorly maintained(by the look of it, seriously it was a dump inside, a bathroom in the middle of the floor which the shower had clearly leaked with mouldy nasty carpet in the hall... joke of a place). I would assume that as good as expensive triple glazing is, its all connected to the same window. Actually having something secondary and not part of the same unit in theory seems like it should kill sound a lot more and from what I experienced certainly did. Three of us were pretty much shocked at how much sound was blocked from it. This was single pane exterior and old windows as well not in the best of condition.

So, maybe something that won't look great, could be removed in the future, secondary glazing? This was just an idea because I couldn't believe it when I saw it. Having just looked it up quite a lot of sites say secondary glazing with a large gap between panes is a much better way to reduce noise than double/triple glazing(and combining both is the best option for utter sound removal).

Depends on the house as well I guess, is it just a few windows at the front that leak all the noise, or is it next door neighbours and it comes in at every window. It depends how desparate you are and how bad it is. IT likely wouldn't make a lot of difference, but try simply taping a plastic sheet across an entire window and somewhat sealing it off, it might not do much at all but would cost almost nothing to try. More permanent proper secondary glazing has only ever looked like crap whenever I've seen it but is stupidly effective in my experience. I would assume cheaper(because single pane is enough, its not external, it should take a fraction of the time to install and on materials.

If it is mainly for sound insulation, then I'd look into secondary glazing.

Many years ago my parents used to live on a very busy dual carriageway. The main room and my bedroom fronted onto this road and the noise was pretty bad. Having double glazing fitted helped somewhat but when they eventually had secondary glazing fitted the difference was like night and day.

This was with around a 6" air gap from the double glazed units to the secondary, with the gap having acoustic tiles around the perimeter.

Secondary glazing does cut out more noise than double or triple glazing. Sarah Beeny proved this on her 'double the value of your house' programme this week.

A couple were looking at spending £19k on new windows for their cottage and Sarah demonstrated (non-scientific tests) that having a secondary glass unit installed behind the exterior windows reduces noise more than triple glazed units.

Oh good, just about to post this.
Yep, "triple glazing" will have a nominal effect.
But secondary glazing with a 6" gap is acoustically very different, this is definately the thing you need to be looking at.
 
Isn't it annoying having to open two windows with secondary glazing? I think I'd prefer to have triple with the biggest possible air gap within the unit. Secondary glazing I've seen also looks awful, like an afterthought and very untidy.

However if I was dumb enough to move next to a 70mph dual carriageway then I guess I'd have to take my medicine regards windows :p.

It does take a few extra seconds yes, and is not as tidy as a triple glazing but it's a much more effective solution to the problem so it's a case of function over form and deciding where you want to make your compromise.
