Triple Glazing or Double Glazing

Hi All,

Looking to get windows replaced and thought I was certain triple glazing was the way to go to eliminate some road noise however recently had another fitter come round and he said he didn't see the point in triple glazing as yes it'll be better for the insulation and heat retention but the noise will still break through because of the trickle vent.

Has anyone here switched to triple glazing with a trickle vent and still noticed a decent reduction in noise from the outside out of interest, or is the window fitter correct and it's not worth me going for triple glazing if the overall decider is road noise?

Thanks in advance.

To combat road noise we mistakingly went from double glazing to triple glazing (glass only on existing frames) which had the opposite effect of what was trying to be achieved which I informed is down to echo chamber effect
The triple glazing had better heat retention but certainly outside road noise was increased
You can get various specialist accoustic windows and maybe worth enquiring about those with reputable glazing companies

My parents had closeable vents and it made a very noticable difference. When you walked into the room you could tell if the vents where open or not just by the sound - it was like leaving the window open!
They installed a pressure air system which means the windows don't need to open or vented.
As for heat loss & fuel bills, it's not something that was considered. i am sure there are stats out there that will show you the cost difference pays for itself over x years, but traffic noise is definately a big factor.

Were they just the basic plastic vents do you happen to know? Not sure if you can get better trickle vents if that makes sense?

Triple glazing would be better for noise reduction, don't worry about the vent, I'm sure they all come closeable. But noise does still get through, because it's weak spot. But apart fro that area the rest would reduce noise. We've had double glazing installed just over a year or so ago and our old windows were much better. Noticed more noise and feels cold around the window area. I can feel air but Idk where it's coming, this is on all windows and their site showed a class windows with more noise reduction and less heat loss, yeah right! They don't make them how they use to. Probably need quad glazing to get same quality as the older ones. (edited)

We had our windows done about 6yr ago now. At the time we found a local company doing triple glazing at the same price as double glazing from others.
Really happy with it, made a huge difference to noise and heat retention. We don't have cavity wall insulation, as around here it has caused havoc with similar houses, and most folks have had to have it taken back out

If price difference isn't much id go for triple, even with the vent as you can just block them after the installers leave so long as you have some other ventilation in the room.

I reckon the installers probably don't want the hassle of the added weight of triple glazing, it didn't look light when they were putting them in (edited)

Would you mind sharing the company name

Depending on how much money you are willing to spend, you can also get what's called "acoustic window vent". It's slightly different to a normal vent, which in it helps to also reduce noise, but when closed, it seals better, so less airflow also (this isn't always a good thing.

The problem is that these vents can get pretty expensive and some look very ugly, but just something to keep in mind.

Triple glazed will help with noise reduction over double glazed, but all depends on the installation itself and if you have a vent or not, meaning if you're going for standard vents then it'll probably be simlar overall in noise depending on the fit itself.

To help this, you can get acoustic foam, which is used when fitting, but again, this is much more expensive than the regular stuff that most fitters would use.

It'll definitely help with heat aswel over double glazed, but again, with the vent and airflow, coldness/heat can come in.

Hope this helps. (edited)

I've just had my 27 yr old DG replaced with again double glazing.. ...it's amazing the amount of the noise it's stopped

Does triple glazing reduce noise better than the SAME STANDARD double glazing?

Of course it does.

Do you have triple glazing?

In my opinion, the fitting is much more important than the quality of the window itself, the plastic trims hide a multitude of sins.

I can confirm if you have trickle vents the noise comes through. I have a bathroom window with a vent and with the window shut I can hear the noise whereas the adjacent bedroom with no window vent, the noise is very very faint.

I have double glazed glass and after lots of research settled on Planitherm Comfort.

Have a look at below two links.
