Double glazing - do you still get condensation?

Trying to get a handle on whether 'modern' double glazing (as opposed to say 10-20year old double glazing, sash windows, crittall windows, single glazing etc) is a barrier to condensation - leaving aside clothes on radiators, ventilation, water from breathing, bathing, drinking and general existing.

How old is your double glazing and do you still have to wipe up condensation in this weather?

Anyone beaten condensation and would attribute it to new double glazing? Which brand or product did you go for?

Anyone find it didn't make a difference?

ilovecakes Wed 16-Jan-13 08:04:22

Our double glazing is a year old and we get really bad condensation :-(

PigletJohn Wed 16-Jan-13 08:56:13

If your home is full of water vapour, it will suffer condensation, damp and mould.

New windows will not reduce the amount of water vapour. If they are a better fit than the old ones and less draughty, the reduced ventilation will make it worse.

If you want. to reduce condensation and damp, open the windows and buy a washing line. If you have money to spend buy a tumble drier and a bathroom extractor.

KatyMac Wed 16-Jan-13 08:58:44

Based on physics - it will make an existing condensation problem worse & may cause condensation in house that didn't have it already

sammydavis Wed 16-Jan-13 09:36:59

I know the whole ventilation argument and how it relates to condensation. Like most people, I don't want to live in a draughty barn though, with windows half open all the time - so that's something we have to deal with. It's also daft to heat your house and then open the windows - on an ecological level and on an economical level.

Our climate means we will always have moisture inside our houses and cold outside our houses and all the ventilation and extractor fans in the world are not going to fix that unless we just give up on walls and roofs and live in the fields.

Condensation occurs when the warm moist air contacts a cooler surface and the 'air' is converted back into a liquid.

The idea of double and triple etc glazing is that by insulating the bigs holes in the walls we call windows, the glass surface will not be cooler than the rest of the environment, and so will not encourage condensation to form.

Obviously this does not affect the level of moisture present in the house - presumably if condensation is prevented from forming by the lack of a cool surface, the air will remain moist and we would probably all be more likely to get chest infections etc.

It's clearly beyong the wit of the construction industry to develop a solution to this issue - (perhaps every house should have a condensation box - a cool area with a suction fan which draws the moist air towards it, and drains the resulting condensation outside).

As I said though, leaving all of that aside - do people find new/modern double glazing an improvement on what they had before - specifically in relation to condensation forming and them having to wipe it up.

Or does everybody leave their windows open all day grin

PigletJohn Wed 16-Jan-13 10:10:39

It is certainly not beyond the wit of the construction or appliance industries to provide extractor fans, dehumidifiers and tumble driers, not to mention windows and trickle vents.

However there are some people who refuse to use these solutions, and if they also insist on draping vast quantities of water around their homes, they are doomed to be damp.

KatyMac Wed 16-Jan-13 10:12:05

I leave my windows open all day

& I will be installing a positive flow ventilation systems which helped massively in a previous house (when I have spare time & money)

If the windows are insulated to the point that they are not colder than walls the condensation will just settle somewhere else

I'm interested in how houses like Huf and over insulated/sealed houses cope with the condensation issue - I think it's by mechanical ventilation

specialsubject Wed 16-Jan-13 11:42:01

this house has 2 year old double glazing and as it is currently freezing cold at night, I am wiping up condensation in the morning. Didn't happen in the summer. Laws of physics.

The bits of the house with older DG get worse condensation.

the decent DG means the place holds the heat from the heating or the sun. Prefer it to the previous rental which had single glazed sashes and was always freezing.

five mins of housework a day. Not an issue.

Pendeen Wed 16-Jan-13 11:59:11

The very latest houses are intended to be virtually air-tight and ventilation is carefully designed / controlled by a combintion of passive and mechanical measures.

Have a look at the requirements here and part f

The calculations are complex and the standards required of the builders are very high including pressure testing the whole house upon completion.

As PJ says, not much is beyond the 'wit' of the construction industry but the challenges are 'interesting' to say the least!

sammydavis Wed 16-Jan-13 13:30:57

Thanks all. I have old double glazing where condensation is annoying.

I also have open windows (not all day though - don't have bottomless pockets and don't believe in wasting fossil fuels as I don't want to sit in the cold and would have to use heating), extractor fans and a tumble dryer (and a dehumidifier which was pants).

So if that's the sum of the solutions available - it doesn't work.

I have however, observed houses with newer double glazing than mine and without obvious condensation and I wondered whether new double glazing - in isolation - was better than old double glazing.

From the relevant replies, it seems that nobody is flying the flag for glazing.

Clearly my neighbours have other, better, secret construction industry machinery operating in the background which keeps their windows water free. Or they get up earlier than me and wipe them down.

I too, am familiar with the platitudes about wet clothes on radiators which is always the stock reponse when condensation is mentioned, but I specifically didn't ask about that and was trying to limit the question to solely the impact of better quality double glazing.

MaudLebowski Wed 16-Jan-13 13:45:31

Seeing houses with newer double glazing that doesn't appear to have condensation on it doesn't necessarily mean that their glazing is better in some way.
It might be that there's less water vapour in their house, either because they're on holiday or out at work all day or they have a MVHR system which pumps damp air out of the house from all rooms. They would also get less condensation if their house was colder than yours.
Top of the range glazing, normally triple and from Finland, will get a lot less condensation than standard stuff given the same circumstances, but it is still possible to fog it up if you try.
So I would say the answer is that better quality glazing will do a slightly better job of getting rid of condensation, but its not a cure all, and you'd have to spend a lot of money on triple glazed krypton filled windows to notice a dramatic difference.

PigletJohn Wed 16-Jan-13 13:55:09

if you are already ventilating, and controlling the usual sources of condensation (you didn't mention that at first) then it might be that you have an additional, less common source of moisture in your home.

this often a plumbing or rainwater leak, it might be from a pipe under the floor such as a radiator pipe of a leaky main, or from an appliance or under the bath or shower.

How old is your house, and have you got a water meter? meters show up leaks as they never stop turning.

sammydavis Wed 16-Jan-13 14:23:59

Thanks MaudLebowski - you've put your finger on it - that a significant improvement in the quality of the fitted unit will make a difference to condensation - by preventing the window from cooling to the level where condensation forms.

Sure, my neighbours may or may not have different circumstances to me but all other things being equal - the quality of the fitted unit makes a difference.

PigeltJohn - I did say in the OP leaving aside clothes on radiators, ventilation, water from breathing, bathing, drinking and general existing. and again, in my next post too.

Specifically, I'm interested in whether new, improved doubleglazing will be less likely to produce condensation.
I can't be 100% sure there isn't another source of water in the house. I certainly hope not!
Again, I'm not saying I suffer 'unusually' with condensation - it's just at a level that I would prefer not to have - that might be more or less than others.

I wanted to garner a few opinions on whether recent replacement windows had many any difference to other people's experience of condensation but instead have gone down the 'usual suspects' route of damp clothing, breathing, baths etc..

PaperFlowers Wed 16-Jan-13 15:22:39

We have just moved into a house with brand new double glazing and a tiny amount of condensation at the bottom of our bedroom window in the morning when it's really cold and the bathroom window steaming up until the extractor fan has done it's thing are the sum total of our codensation. I do keep the trickle vents open most of the time though.

Our neighbours do not have DG and they all seem to get condensation - some worse than others. All of the houses were built in 1998 and are identical. We donl't have a tumble direr but only do one load of washing oer week (two max).

I love our double glazing - we have the heating on so much less than we would have needed in our old place.

Pendeen Wed 16-Jan-13 15:50:00

Just a thought OP, are you talking about the 'old' windows being double glazing or secondary glazing and is the condensatin on the inside surface or between the panes (or both)? You mention different types of frames in your introduction.

To answer your general question yes there is a huge difference in performance between (for example) steel frames with secondary glazing and brand new A rated PVCu windows with low emissivity glass and inert gas filling.

As an aside - replacement windows come under the Building Regulations so a FENSA registered contractor needs to be used unless you fancy dealing with Building Control.

sammydavis Wed 16-Jan-13 15:58:06

Thanks PaperFlowers - that's really useful - especially given all of the houses are so new but yours is the one with the newest double glazing - the perfect scientific experiment wink.

Would you mind saying what kind of glazing you bought: brand, double or triple - what the gas filling is - would be really helpful.

Cheers Pendeen - I have old standard UPVC double glazing. At various times I've lived with Crittall, secondary, wooden sash, - any combination or specification of rubbish windows you can think of and every house has been plagued with condensation.

Increasingly though, I've noticed it's less common to see water streaming down windows and I'm keen to buy whatever windows achieve that!

PaperFlowers Wed 16-Jan-13 16:13:09

Yes I am very scientific (and a bit smug about our lack of condensation as our previous place was an absolute nightmare).

I'm afaid I have no idea about most of that as they were done just before we bought the house. They are definitely new PVCu units (ie they took the original wooden frames out and replaced the lot) and they are double not triple I'm sure.

We have double glazing (new) and I leave a window open all day and night, don't hang washing in the house, have fans in the bathroom and kitchen, air bricks, vents in two of the bedrooms and we still have terrible condensation. Argh.

0blio Wed 16-Jan-13 21:17:04

Am watching this thread with interest as I am about to replace some of my wooden framed double glazed windows with good quality upvc ones.

I really hope it helps my condensation problem as my windows stream with water on cold mornings and despite drying it every day, the window frames are rotting in some rooms because of this. Not only that, but I frequently also have to clean mould off the inside of external walls.

I have a condenser drier, three extractor fans (including one with a humidistat which is hopeless - I have switched it to manual operation as it rarely came on) and a dehumidifier going 24/7 (again pretty useless, except for drying washing - and I'm dreading my winter elec bill!)

I have lived in quite a few properties and have never known condensation like this. We have no leaks anywhere that I'm aware of, but I wonder if the super thick loft insulation installed by our energy company perhaps contributes to the problem.

PolterGoose Thu 17-Jan-13 12:18:49

However fantastic your windows are they will not reduce condensation confused all that will happen is the condensation will find the next coldest surface, and, IME, wiping windows every morning is a lot easier than dealing with condensation related mould behind furniture and in cupboards. I'm struggling to understand your problem as you won't discuss all the usual causes of condensation hmm

sammydavis Thu 17-Jan-13 12:39:33

Poltergoose - I don't have a problem and I don't see what's hard to understand.

There are many causes of condensation.

There are people who love repeating ad infinitum platitudes about the causes of condensation - I know the causes - that's why I said I'm not asking about the causes

Rather than put up with more of the usual about wet towels and extractors etc etc - I specifically did not ask about the 'causes' of condensation - people want to go on about wet clothes, extractors, tumble dryers even whens asked not to.

I specifically said leaving aside wet towels etc....

I straightforwardly asked whether new double glazing affects your 'experience' of condensation.

Have you got new double glazing and did it affect your experience of condensation?

Sausagedog27 Thu 17-Jan-13 13:19:11

Gosh op- you do come across a bit prickly shall we say- people are only trying to help.

Surely you need to address the cause of excess moisture and condensation in a house.

You can throw money at new double/triple glazing, but as has been said, the excess moisture will just find the next coldest spot in the house.....

digerd Thu 17-Jan-13 13:21:06

When I moved in here 14 years ago, I had 30 year-old double glazed Metal alluminium frames, which were dripping with condensation , especially in my bedroom which is a flatroof extension.
10 years later I changed them to UPVC frames, and the condensation stopped immediately. But was horrified to find that there was condensation on the OUTSIDE on a very cold night.
This is <apparently> due to the superior E outside coating which helps stop heat loss through the windows.
But I now have no net curtains at windows as have georgian barred glass. My old curtains would get soaked by the condensation too.

PigletJohn Thu 17-Jan-13 13:22:52

The reason people keep saying "wet washing and lack of ventilation causes condensation, damp and mould" is because it's true.

I have grasped that it's not something you want to hear.

PolterGoose Thu 17-Jan-13 13:27:11

You said Specifically, I'm interested in whether new, improved doubleglazing will be less likely to produce condensation.

And this is why it feels like you are missing the point because windows cannot produce condensation

PaperFlowers Thu 17-Jan-13 14:18:11

Ok, I have a question of my own now if I may.

So, we get virtually no condensation accept for around the front door which I noticed last night (I think the seal around it needs seeing to) and when the bathroom steams up after a bath. We keep the trickle vents open the whole time and use extractor fans when bathing/cooking. We dry one or two loads of washing in the house per week at the moment and hang towels on the bannisters.

Is my house going to go mouldy somewhere else instead and where should I be checking? We have just moved out of a flat that was truly horrific for mould and damp - to the extent that it made my DP ill. I don't want that to happen again and thought I was sorted with my lovely double glazing, newish house and good ventilation.

The house is 15 years old and appears to be free from leaks, although we do need to get a leaking gutter sorted soon or that will change.

PigletJohn Thu 17-Jan-13 14:30:35

look inside and behind large furniture which is against an outside wall. .

behind kitchen cabinets and the pipes

at the top edges and corners of upstairs wall and ceilings

Especially look at the wall under your leaking gutter

also look in the loft and see if water is condensing on the felt under the tiles, or on any cold tanks or pipes

If you have any holes in the ceilings for downlighters, water vapour will rise up through them.

KatyMac Thu 17-Jan-13 15:18:18

TBH upvc windows are one of the safest places for condensation to alight. So much better than wooden furniture or the backs of picture frames or floorboards under the bath

sammydavis Thu 17-Jan-13 15:45:04

Poltergoose - you don't want to answer the question I asked - that's fine.

You want to tell me what causes condensation - I know what causes condensation.

Please don't sift and edit the hundreds of words I spent explaining this to you and then re-frame my question to try and highlight to anyone interested that sammydavis is not as clever as clever Poltergoose.

Thank you PigletJohn -I have said many times now I don't want to know any more about the causes of condensation.

I have checked through all of the causes and in many homes there will still continue to be a residual persistent problem amount of condensation despite there being no water leak, no wet clothes on raditors * no breathing * no batsh and despite the presence of, * extractor fans, * good ventilation.

This is the nature of the housing stock in this climate in this country

I want to know whether new double glazing has made a difference to the amount of condensation you experience.

From my very first OP - right at the top of this page - I made this clear - please read it again if you are still in doubt

Despite my clarity, many posters insisted on giving me the causes of condensation again and again and again and were clearly not happy that I was not grateful for the answers to a different question than the one asked.

I appreciate the intentions were good but the question was deliberately worded to focus the answer on the effect of new double glazing on condensation.

Some people saw this easily and gave appropriate answers directly related to the question.

I am not saying I don't want to know the causes of condensation in order to deliberately snub my nose and spite people.
I am not saying it because I am an ignorant fool who wants to spend £5k on new windows only to realise I should have removed my wet towels from the radiator and saved myself a packet.
I am not saying it because I have taken a personal dislike to anyone or because I have any axes to grind or vendettas to pursue

I am saying I do not want to know the causes of condensation because what I in fact want to know is whether new double glazing made any difference to condensation in other peoples houses.

That's the question.

Does anybody know if regularly taking aspirin has a long term effect on heart disease?

I do not want to know the causes of heart disease.


PolterGoose Thu 17-Jan-13 16:15:42

Did you mean to be so rude?

sammydavis Thu 17-Jan-13 16:29:10

Yes or no - which answer will get you off my case?

digerd Thu 17-Jan-13 16:41:54

My new 5year-old double-glazing which replaced 40 year-old, ridding me of the terrible condensation I had in my bedroom < but creating condensation on the outside of the window> were from Anglian.

PolterGoose Thu 17-Jan-13 17:15:15

Lovely hmm

You asked if newer double glazing would reduce condensation, lots of us responded saying it will probably reduce condensation on your windows. However, we have also added a caveat that you may then experience other effects of condensation, which doesn't just form on windows, in out of the way places in your home which can lead to mould growth. I can't understand why you are having such a problem with people supplying helpful responses which warn you of the potential pitfalls.

Not one of us has been rude or aggressive to you, but your responses are coming across as very odd.

PigletJohn Thu 17-Jan-13 17:55:19

Hi Polter (I'm not speaking to Sammy any more)

I have a UK house, and in cold weather, I get condensation on the smaller bedroom windows if windows and door are both shut. In cold weather I get temporary mist on the bathroom window while running a bath, but it is soon gone thanks to the extractor. I don't get condensation in any other room. Two of us breathe, heavily from time to time, but no wet washing is ever draped around the house.

In my other (now sold) empty house, with nobody breathing, I have never seen any condensation or damp anywhere, except following a water leak or replastering, regardless of weather and heating patterns.

The homes where I have seen severe condensation have always been those where people drape wet washing around their homes and over radiators.

KatyMac Thu 17-Jan-13 18:45:57

PigletJohn - I run a business from home so I use inordinate amounts of hot water for washing up, loads of cooking with pans, lots of washing machine loads and lots of people breathing.

We have some condensation on the windows upstairs in the morning & after a bath

So I know my problem is lack of extraction in the bathroom - but we can't access the roof or bathroom window from the outside & we are attempting some some of mechanical extraction - but it's tricky.....venting to the loft probably won't help

Our only other place of condensation is the front door early morning again - it's wooden, badly fitted and has cracks where the panels fit together & I know what the solution to that is; but I'm not prepared to replace until we sort the MV in the bathroom

VivaLeBeaver Thu 17-Jan-13 18:52:50

Aspirin therapy is good for people who have had a TIA or an MI or with coranary heart disease. It can reduce heart damage, reduce the chance of another MI and reduce the chance of a TIA. You have to weigh up the dangers of stomach ulcers.


lljkk Thu 17-Jan-13 19:04:19

Our DG is 5 years old & we get condensation, mostly in one type of room.

It's not where we dry the clothes on radiators, or where the cat water bowls are, or near the toilets, or near the standing water left in the washing up bowl.

It's in the bedrooms: because people breathe out all night! The nerve of them.

Sausagedog27 Thu 17-Jan-13 19:05:58

In answer to your question- double glazing may mean that water vapour in your home does not condense on the windows. However, if you do not address the source of the water vapour, in all likelihood this will just condense elsewhere.

By the way, in my experience, it is not the nature of the housing stock in Britain.

I don't understand why you are being so rude when people have only tried to help you. It's not as simple as yes or no.

PigletJohn Thu 17-Jan-13 19:08:00


time you bought a dishweasher, to cut down on water and energy, and a cooker extraction hood.

can you, or someone on a ladder, reach the outside wall of the bathroom? Is it a house or a flat? It is possible to fit a duct and grille from the inside, but I don't know how good the grilles are. Not suitable if bits of brick might fall on someone's head.

You can duct through the loft and exhaust the duct through the eaves, or cut a hole in a gable wall. It is possible to vent through the roof, but you need a roofer or it will leak.

If you get a Core Drill from a tool hire shop you can cut the holes for lots of ducts on the same day. You will enjoy it, but don't work off a ladder, they are very heavy and powerful. You can drill from inside.

KatyMac Thu 17-Jan-13 19:13:30

Thanks PigletJohn - the dishwasher died in the flood last November & is on 'saving up for' & the bathroom wall/window is above a large conservatory....which can't be climbed on sad & I don't want to drop a brick through it either wink

It's the loft/eaves thing I need to get my head around - in my last house a positive flow ventilation system worked wonders but the ceilings were higher & I didn't notice and cold air coming in....I think I might in this house

PolterGoose Thu 17-Jan-13 19:33:26

KatyMac, if you positioned an extractor so that the external duct came out within reach of the window you could reach out to glue on the vent as well as seal it with exterior silicone. Our 2 new extractors just have a piece of drain pipe through the hole and the vent fits very nearly on the end.

KatyMac Thu 17-Jan-13 20:10:22

Hmm, that would have to be above the window I guess - I'd worry about drilling the home I think

PigletJohn Thu 17-Jan-13 20:15:26

there would be a lintel above the window, don't drill there.

I suppose you could put it to one side (not directly above a bath or shower)

or I think use a ducted one in the loft and let the duct exit where it's not above the conservatory

Or, you could drill through the wall above the conservatory, and put a ladder through the hole made by the falling brick grin

KatyMac Thu 17-Jan-13 20:16:59


I think either a vent into the loft or a positive flow ventilation system

We'll see

GentlyGentlyOhDear Thu 17-Jan-13 21:14:42

We're really struggling with condensation in upstairs rooms. I have a tumble drier so don't have any wet washing in the house, I have a dehumidifier on and have my bedroom window ajar, yet on cold mornings I have a huge bay window streaming with condensation. We've started to get mould on the celiling of the bay window too.
Where can all of the moisture be coming from? Is it jst because we have huge windows? They practically go the width of the external wall. Could the felt on top of the bay window need replacing? Would that have any effect? I just can't understand where all the moisture is coming from confused

DialsMavis Thu 17-Jan-13 21:27:53

Until recently I have always lived in homes with double glazing, never new houses though. My past 3 houses have been 90-150 years old. I now live in a 30's semi with original windows at the front and old aluminium (I think!) double glazing at the back. The old double glazing gets a tiny bit of condensation on cold mornings, the original wooden windows are streaming every morning, if we don't keep the heating on overnight the water is dripping off the window sills onto the carpet below, it is horrendous! We moved here to save £ and I think the £200pcm saving will be completely over ridden by the gas bill as the boiler is so old and the windows so draughty, my old house was gorgeous and this one is an 80's monstrosity.....wahhhh

PigletJohn Thu 17-Jan-13 22:29:16


if you are already ventilating, and controlling the usual sources of condensation then it might be that you have an additional, less common source of moisture in your home.

this often a plumbing or rainwater leak, it might be from a pipe under the floor such as a radiator pipe of a leaky main, or from an appliance or under the bath or shower.

It could well be felt on top of the bay window. felt does not last long. See if you can get lead or EDPM (rubber). If it has been leaking you will need to replace the board, preferably in WBP ply.

If you tape a piece of clear plastic tightly to a wall or ceiling, you will see if it is condensation (wet on the room side) or penetrating (water on the wall side).

How old is your house, and have you got a water meter? meters show up leaks as they never stop turning.

GentlyGentlyOhDear Thu 17-Jan-13 23:11:28

Thanks for reply.
It's a 1950s semi. We do have a meter so will check it out. The house was empty for 18months before we moved in - would that make a difference? And the seal on a couple of the panes has gone - would that make a difference?
I'll get the bath panel out to check under it as the window in there is always condensed (when nothing has been on).

Since you're on the thread - I'll hijack and ask a quick boiler question - ours is about 10 years old and every few months we get a funny smell coming from the boiler cupboard that lasts a few hours and then goes. It's like a garlic/cooking vegetable smell. We had a boiler engineer out who cleaned and seviced it all and found nothing (he suggested maybe a dead mouse!!) and we had National Grid out to check for leaks and were given the all clear. Any ideas? The house was rewired when we moved in so don't think it is an electrical issue.

PigletJohn Thu 17-Jan-13 23:23:18

might poss be a leak

bleed a radiator onto a bit of kitchen towel and sniff it, see if it's the same.

hot electrical accessories smell fishy. could it be that?

GentlyGentlyOhDear Thu 17-Jan-13 23:27:24

It's not fishy, more like a roast dinner type smell. Will bleed a radiator and see. If it does smell the same then does that mean there is a leak somewhere in the system? Would that then require a plumber to locate and sort?

Busy weekend of diy for me my DH!

lisianthus Fri 18-Jan-13 00:14:20

Hi Sammy, just wanted to say thank you for starting this thread. I've been wondering about this as well (as have all the other people with their own problems with condensation who have joined in). Sorry you've had people join in to patronise you then get snotty when you have been frustrated with that rather than being "appropriately grateful".

Thanks to PaperFlowers and her interesting info re Finnish windows!

digerd Fri 18-Jan-13 12:57:24

Also found that closing the curtains at night in the bedroom, caused more condensation than in the bedroom with curtains not drawn.

EricNorthmansFangBanger Fri 18-Jan-13 13:52:06

We used to have single glazed windows. Very old and rattling single glazed windows. The amount of condensation everywhere was ridiculous. There used to be puddles of water on the window-sill every single morning without fail. The house was freezing.

Then we got double glazed windows everywhere. House still gets nippy. Condensation on windows is minimal and some days we don't have any. Our problem now though is mould. I will admit that we have been lax in the airing out of the house, so trying to improve on that I just really dislike the cold We also have some water marks on the wall and have been told it's due to condensation and we need insulated board put up in the loft. So there has been a big positive to the condensation problem but it's left us with some mould problems. BIL used to own this house before we did and MIL goes on about BIL never having problems with mould before but that was due to the single glazed windows and the fact it was like living outside before we got the double glazed windows.

throckenholt Fri 18-Jan-13 16:02:29

We get condensation on the bottom of bedroom windows - not a big in itself, but it puddles on the windowsill and often gets forgotten and it not doing the windowsills any good sad

No way round it that I know since I can't stop people breathing all night !

digerd Fri 18-Jan-13 18:21:59

My bedroom was always the worst, but always shut the door to keep heat in. Only me in the bed on the other side from window. Assumed it was my breathing as bedroom is small, compared to other people's. But realise I should keep door open. The modern convector radiators are better at drying the humidity than the old flat panel rads.

0blio Fri 18-Jan-13 20:43:29

Glad to hear new windows helped your problem digerd.

I've been warned about the condensation on the outside of the glass by the window company. They say it's a good sign.

digerd Sat 19-Jan-13 15:46:45

I know, but I was horrified the first time I opened my curtains as thought it was on the inside of the 2 pains, and it was like looking at thick mist in the garden instead of my lovely view. It was in January 2008. Don't look anymore as leave the curtains closed until later in the morning.

Badvoc Sat 19-Jan-13 18:54:53

Well i have old dg at the back if my house and newer at the front - only 5 years old.
Both get condensation, the older windows worse.
When i was a child we didnt have dg and git condensation.
Its not really something you can avoid
Perhaps purchase a dehumidifier?

We dont get much condensation thanks to 4m high ceilings, my obsession with airing the house and religious airing of bathroom after showers even when freezing outside. But when we put in secondary glazing, the condenation disappeared from the rooms where we put it. Hth.

I leave my windows slightly open all the time, and still get really bad condensation in our bedroom every night (think absolutely dripping, can't see out of them all day). If I have to dry washing in the house I always put it in the small bedroom with the dehumidifier on - I never dry it in our bedroom.

Accidentally left the heating on all night last night and for the first time that I can remember during winter we have no condensation this morning!!

When I close the curtains in front of patio doors, in the morning there is some condensation lower down - metal framed 50 years old-, only in the winter. I drew the curtains back, so that the warmer air of the room could get to them, and low and behold - no condensation. The new UPVC patio doors are thicker and don't fit the opening, so rather than have the wall knocked down to make the opening bigger, I left them as they were.
I do not get condensation on the inside of my front windows as is a bungalow and the sofits overhang and protect. The back is a flat roof extension so no overhanging roof also open to fields and a canal and is always colder outside than the front.

Someone in our family's bought a new build house and the extractor fans in the kitchen, utility, 4 bathrooms all run 24/7. Luckily they are silent.

Is this now standard practice?
