THE HOUSE I MOVED INTO HAS A LARGE MAINLY GLASS CONSERVATORY AND THIS WINTER AM HAVING MAJOR CONDSENSATION PROBLEMS, IN SO FAR AS WATER IS COLLECTING ON ALL THE WINDOWS AND ROOF AREA, THEN DRIPPING DOWN. I HAVE HAD TO MOVE MY FURNITURE OUT AS EVERYTHING IN BECOMES COVERED IN MOULD. AM NOW AT THE POINT OF THINKING OF KNOCKING THE WHOLE LOT DOWN. AM A SINGLE MUM WITH NO HELP!
You have the advantage of a weatherproof room so knocking it down seems a bit desperate. Get a good de-humidifier - £150+ - fit a continuous drain pipe from it to outside (a bit of plastic tube) and just leave it running.
Condensation is always the result of warm moist air meeting a cold surface.
I would guess that your conservatory has an open access from the home, no door to close, and the warm moist air is moving from the home into the conservatory and condensing?
Is this happening, is it making your home cold?
Or you have a heated conservatory and are turning down or off the heating?
Do you have blinds that are closed at night, causing a drop in temperature between them and the windows?
Possibly you have live plants in the conservatory, or in your home that are breathing out water vapour?
The best way to deal with condensation is to keep the temperature steady, then the air will hold its moisture.
And have warm air moving past the cold surface to keep the surface temperature up to a point where the air does not chill and the moisture falls out, as during the day.
