Condensation

[NISAR1]

Hi,

I have recently replaced a failed double glazed window for a triple glazed window. I have noticed more condensation in the morning. I would have thought it would be alot less condensation being triple glazed. Can anyone shed some light or have I purchased a not fit for triple glazed window 🤔?

Thanks

I think a triple glazed window would still be the coldest element in your wall. If it's cold outside and damp inside then condensatiom could still occur.

Double/triple glazing does not stop condensation.

Is the condensation on the window's inside (i.e. indoors) or on its outside? It is possible to have condensation on the outside of a double-glazed window, particularly early in the morning, after a cold night.

My friend lives on a narrow boat which had dreadful condensation on the windows so he invested in anti-condensation glazing and it works.  No more condensation.

Triple glazing is marketed as a solution to condensation problems so you are right to be miffed if it hasn't worked for you

Contact the supplier for advice and if you are not satisfied ask your local council who they can recommend to independently inspect the window to try and get to the bottom of it.

I've read that the cons outweigh the pros for triple glazing in the UK.

Our normal climate just doesn't merit the extra outlay.

Are you sure it is inside? I have a couple of triple glazed windows and they do get very damp outside some mornings but never inside.

Hi,

 

Yes the condensation is on the inside and I do use a window vac every morning. The room is small and has 2 children sleeping in it. 

Thanks

That is not good, my guess it is north facing.

My north facing windows are prone to condensation in the very cold weather and I use a dehumidifier in the bedroom.  That has cured the problem but really you should get on to the people that installed the window.

@bookbinder...yes, i often get it on the outside(not as much though) as well as inside of my double glazing.
I have a small Karcher window vacuum that sucks it all off in seconds, well worth the money, also use it on the car ....

In general, triple has a lower 'U' value than double. The lower the value, the smaller the amount of heat lost.

The number of panes though, is not the only factor. I don't know how old your double unit was, but it was probably the standard 28mm unit. That's 2 x 4mm glass with 20mm cavity.

It's the cavity that does the work. Replacing it with a triple  would result in 2 x 8mm cavities. So possibly little or no improvment.

When triple is fitted in new purpose-made windows, unit thickness can be  48mm or even more instead of the usual 28mm. There's the improvement right there.

And.............  there's 'K-glass'. Does your new unit have that? (Low-emissivity glass). Argon-filled cavities are another thing.

Just like me Nisar, it goes on and on 😆

Plus it's November on our dear soggy isle. Trickle ventilation and/or more background heat would deal with it.

Thankyou everyone for your input as always much appreciated.
