Any tips to stop condensation on windows?

martinmck

I tried trickle vents, dehumidifiers etc and nothing stopped the condensation on the inside of the windows in my flat. I replaced the glass with high energy rating glass and this has solved the problem! I don't think many of the big companies use this type of glass so you may need to hunt about.

Our bedroom window is the only one in the house that gets condensation. It is also the only room with a mould problem. It is always the coldest room in the house, even when the heating is on. It is also the only room with a vent in the wall, where I can feel a draft come through. It seems likely this is all related.

We have the trickle vents open all the time and don't dry clothes in there (we dry clothes in the spare room and that window is fine). We shower with the door closed and the shower is at the other end of the house anyway. I can't think of anything we're doing that's causing it. Is it likely to be problem with that specific window since no other windows in the house have this problem?

Have you tried blocking up the vent in the wall to see if it helps?

I always thought blocking vents was a big no-no. I'll give it a try, thanks!

Blocking the vent didn't work unfortunately. It's actually got worse, but that could be because the weather is colder. Our home report said that we have cavity wall insulation, but I've heard of botch jobs on this before ie it's only there around the hole they drilled and doesn't do right to the edges/corners, so I'm wondering if this happened here as the mould growth is mostly in the corners. The walls in that bedroom are colder than any other external walls too. Could this indicate a bad insulation job?

Any other suggestions are welcome

Edit: I've also read somewhere that putting up a polystyrene veneer on the walls keeps the walls warm and prevents condensation on the walls. Has anyone does this? Is it worth doing?

We have no cavity wall insulation, well we have no cavity. All of our rooms suffered badly with condensation on walls (especially behind furniture) and windows so a couple of years ago before decorating a bedroom we fixed battens to the wall, placed polystyrene sheet insulation between the battens and then plasterboarded over it before decorating. This made a heck of a difference in that room, we still get condensation on the window in the morning but the walls are as dry as a bone with no mould etc. We have repeated for two further rooms and as and when financies allow we will continue to do the remaining rooms.

We live in a newly (less than 2 years) flat with Swedish triple glazed windows & patio doors and suffer horrendously with condensation.

We rarely dry clothes inside, use the extractor in the kitchen when cooking and have an automatic fan in the bathroom to extract the moisture. Every morning in winter we have to go and wipe all of the windows/sills/walls in the window frames, whether we have the windows ajar or not. All windows have trickle vents which are open. We rarely put the heating on as the property is so warm - so far we've had the heating on for 3 hours since the start of November. I love our property, but this moisture is driving me potty. :wall:

Any clues as to what I might be able to do to alleviate this issue?

Buy a dehumidifier or open the windows more often

Your problem is the house is too well insulated

lack of ventilation .
