Double / triple glazing and noise reduction

moneyistooshorttomention

I'm wondering where people manage to find firms to do tripleglazing. Am I missing something?..as, any time I looked, I was only able to find firms doing doubleglazing.

Is it a case of pick whichever doubleglazing firm you choose and telling them to do tripleglazing and they will amend accordingly (ie even if they don't say they do tripleglazing)?

I actually googled it.
Found maybe 3 firms originally ( when the wood frames were done) couple years later many more firms were doing triple.
Seems more common now, however the company I chose for the UPVC did not advertise that triple was available, when they called me I simply asked. As in before you come out to measure, do you even do triple? Cos if not there's no point wasting our time.
The usual big guns came out to quote even though I had said triple only please.
They quoted for double and then said OK we will do triple for you.
I thought they were lying to be honest.

There is a company near me using, I think, the Swish profile. They use the standard window profile, but of course triple glazing is thicker and is not meant to fit in this profile. Consequently the glazing beads have a bulge out profile and protrude past the window. I believe this looks awful - remember that the beads are internal and this is what one sees every time one looks at the window.

You don't need triple glazing, you need a double glazed unit that incorporates an acoustic laminated product. You will only need this on the front of the house by the sounds of things.

Very few DG companies will know much about these products but their actual glass supplier will know all about it.

The exact requirement is based on the decibel level and the frequency of the noise you wish to keep out.

All the residential new build and refurb work in London has an element of acoustic glass these days, mainly on the first three floors.

Google Stadip Silence for a clearer understanding.

Plenty of misinformation on this thread.

I've also had triple glazing fitted - as said earlier the extra per window isn't much, my fitter said it was an increase of about 20% per unit - at the end of the day other costs such as disposal of the old units, delivery and labour are the same - hence the increase isn't much on a job. I didn't find the reduction in noise dramatic, but then I was replacing double glazed units that were about 16 years old. The warmth has been noticeable, especially as the sofa is under the window. In fact my house is unbalanced, the front where I had the windows replaced is toasty, whilst the back is now cold - I need to get on and get the rest replaced!

There is very little to gain from triple glazing over good double glazed units in the UK. As an example a 4-12-4 softcoat Low E unit filled with Krypton will have a U value of around 1.1 , if you go for triple glazing the U value would be down to around 0.7 at best so the saving really is peanuts. Its a few £p a year.

I would also mention that the U value of the overall window frame/incl units can be different depending on material used (Upvc,Aluminium or timber) .

Triple glazing does make a difference in Scandanavia where they have far lower temperatures for far longer than we do.

Re: Noise reduction, it can be improved by having 2 different thicknesses of glass making up the units so 4mm one side and 6mm the other or even having 6.4mm laminted on one side will be an improvment.

Thanks for the input people.


Triple glazing was fitted by a local company. The room went from 75dB of road noise, to averaging 38dB. The old aluminum windows were in really bad shape so it was good to get done.


What has now become apparent is a circular 127 diameter vent to the outside is now the main source of road noise entering the room, so just need to find something breathable to fill the vent space up with so that there is still ventilation, but less noise coming through. Will also put a cowl on the external portion too.
