My parents have a lean to conservatory on their kitchen. Approx six by twelve feet.

Brick to waist height topped with double glazed ? windows (some can be opened) on three sides. Modern white PVC/metal and glass door. Flat roof atop it all.

It has a sink, a washing machine- used every day of course and two fridges. So as the windows and doors are shut for security and there is plenty of moisture and heat, the ceiling gets mouldy.

I am going in a few weeks and sorting out some form of ventilation is in my huge list of jobs.

In an ideal world that would be some form of lock on a small opening window. Is there such a thing? If so I could ask East Yorkshire Glazing who I believed installed the windows.

Otherwise I am thinking of an expelair/ventaxia type thing.

I think it would be too big a job for me in the time and with limited tools.

Any suggestions e.g. in brick or in glass window? Powered by electricity or just wind? Knock a brick out and put in a vent?

I think you'll have a job keeping that moisture free. Lots of glass and steam from a sink plus heat from the fridges. Plus anything that's coming from the kitchen. Hmmmmm

My conservatory top windows can be locked fractionally open. Have you tried that?

[Taxi_Driver]

They must be quite old double glazed windows.....as its quite a number of years ago that H&S meddled and insisted windows had to have a ventilation setting. Originally PVC manu's just cut a slot in top of the frame and put in a flappy paddle that you could open for ventilation. Completely making double glazed windows useless imo, as in you've got a double glazed unit with a flap, as if that's likely to stop drafts and the cold when the flap is shut. Now the manu's have done away that useless idea (well, most I think) and gone for a lockable slightly open position of the window.
It was the first question I asked when I was considering double glazing. "Do your windows have a slot cut in them for ventilation or a lockable slightly open postion?" The windows I had fitted have the lockable slightly open position 

Maybe something suitable in these links for the windows

Some good ideas there, thanks.

It was only done last year so may have some ventilation included.
If they are user adjustable then I bet that the users will have them shut to keep the draughts out.! Those opening window locks look a good proposition.

Thanks

Locks are probably "espagnolette" and the keeps are usually individual with a vent facility to enable window/transom to be opened app. 10-15mm and locked in place. The cam element of the espag locks into the outermost "U" of the keep

Exactly like mine, though without the flowery language.

We stocked them as night vent keeps as nobody used the correct term!

Do you stock 'day vent keeps' as well?? As I tend to leave a couple of windows downstairs in the vent position during the day

I have a small dehumidifier running at the bottom of a large ,long hall . As we tend to live at the opposite end of our house that end of the hall gets cold and with the exit door being at that end damp air can enter as we enter/exit . Black mould spores were always a problem on the ceiling . I bought a couple of small dehumidifiers from Aldi several years ago and have one running constantly( 8-9 months of the year  )  down in that area . The problem is virtually eliminated and it's surprising how much moisture is withdrawn from the atmosphere . These small 12vdc via a transformer dehumidifiers are very good and cost nothing to run.

So this conservatory is fully open to the kitchen? 

[Varche]

No it was built years ago and tagged onto the outside of the house. The kitchen door (was rear entrance) goes into the conservatory which has its own back door.

So as they go in and out of the kitchen into the conservatory to get milk etc out of fridge , moisture and warmth escapes from the kitchen.
