Does good triple glazing eliminate condensation from windows .

Ryan davis

I'm considering getting triple glazing it might sound mad but I just can't stick the condensation on my double glazed windows during the winter , on the bedroom windows the condensation is nearly half half way up the window it drives me nuts .People say this is poor ventilation , I have 4 inch wall vents in the room and I was considering the air ventilation heat recovery systems but they say you need an air tight house for this to work efficiently. My double glazed are only 10 years old and in good condition I also found a sticker that says they are argon gas filled and have low e glass so that means they are good but considering they also say condensation is from the warm air meeting the cold glass I wonder are those double glazed as good as they say . I just don't know what to do so I'm wondering has anyone got triple glazed windows and have no more condensation on the windows as a result.

Triple glazing may help address the condensation - but only if the problem that you want to address is the window condensation.

I fitted low-e double and triple glazing in my house to address the heat loss and condensation associated with the low quality double glazing which fitted at the point of build and it lessened the condensation, but my relative humidity remained high.

I'll put it this way: the condensation is a leading indicator of high humidity in the house, whether that be caused by cooking/cleaning/human activities. If you measure & manage the humidity then the window condensation should lower, but you're always going to have periods where it jumps due to external effects.

I'd advise trying to identify the sources of condensation (there are many posts on this forum on that topic) and address them with a mixture of reduction, ventilation and dehumidification.

Good luck!

i would guess that there are other issues at play rather than the windows. are you getting cold bridges around the windows or draughts around or through them.

are the vents open

are you heating the house during the day or just the evening

why have you such high humidity in the rooms. are you drying clothes near by, do you open he windows to let out mointure

how about a dehumidifier plumbed in to pull the moisture out of the air.

you get condensation on the outside of triple glazed units !

Thanks , yes the worst is our bedroom presumably as there's 2 adults breathing all night in the room . I've seen people say leave the window open slightly and while this does help very slightly it's not ideal when it's freezing . Also another suggestion is a dehumidifier but this is also not feasible with the running costs and also the noise factor plus the warm air it blows out the back. I've noticed the small bedroom room is also pretty bad this year as my smallest lad gets older and he seems to get constant chest infections . I find the 4 inch wall vents don't help especially as these are always open. It's not a damp house but I suppose with houses becoming more air tight the moisture must go somewhere . I put a fan In the bathroom and also there is the extractor fan in kitchen. It's just very frustrating you'd get over the standard 2 inches of condensation at the bottom of windows but like I said mine and the child's bedroom it's over half way up in cold spells.

I'd take that

Get an air tightness test done and see how leaky it is.

You can also get heat recovery ventilation devices to fit inside those hole in the wall vents.

Check partel.ie and you'll find them.

Lunos is the name I think. Two of them could fix the problem

No draughts windows are well sealed

Maybe cold bridges on reveals

I never dry clothes in house

Walls vents always open

We generally only heat the house in evening as no one at home during the day except weekends.

I was doing some research on them and apparently they are ineffective with out windy climate

These things?

They're fans so I'd have thought they would work fine. Only tricky bit is getting a power supply to them

Be careful what you wish for .

I replaced french doors and two double glazed windows in my kitchen/ dining room (north facing) with a double glazed patio door and 2 triple glazed windows.

The majority of mornings between September and March there is a lot of condensation on the outside of the triple glazed windows that often does not clear til early afternoon.

Its a sign the triple glazing is working and the room is a little warmer but it looks bad and makes the room very dark .

I won't be replacing any of the other windows with triple glazing .

Ryan davis

Ya those , I read earlier they are ineffective in our windy climate but then again that just 1 company's opinion

Ryan davis

I understand but I'd much rather have it on the inside where you get mouldy windows, blinds and cills, did you have condensation on the inside of windows before you replaced them with triple glazed ?

Yep, we thought we had a problem at first as 2x glazing didn't seem to fog up but 3x regularly fogs on the outside.
