Lots of condensation in conservatory

    I have a 'conservatory', lean-to connected to the rear wall of my house on the N facing wall.. It has a corrugated acrylic roof. This autumn I'm seeing a ton of condensation, more than previous years I'd say. It's practically raining in there. The space isn't heated, though the oil burner is in a sort of concrete structure connected to the conservatory. The only changes from previous years are: replaced the corrugated acrylic last summer, and also insulated the North facing rear wall of my house on the inside.

    I'm going to try leaving the conservatory windows and door wide open to see if that gets rid of the condensation. Is there anything else I can do? I have a dehumidifier but this 'conservatory' is a long way from being air tight, so it's not really a space where I'd ordinarily use one.

    I have a medium term plan to replace this conservatory with a proper double glazed window constructed one. I'm sure the double glazing would reduce the condensation but I'm concerned now that I'll still get some, and it will a problem still. What do you think?

    It has been very wet this Winter in comparison to last year, much of the damp in the air can be attributed to that. It's typically the warm air from the house - carrying lots of damp air from the living spaces - hitting the cold surfaces of the conservatory which create the moisture. That's as long as you don't have damp coming up from the floor and walls/foundations.

    If you can remove much of this moisture at source - kitchen, bathroom, drying clothes, etc, - then that will cut down the overall humidity. Leave bathroom fans on for extra time is a good one as it drys out the environment as well as drawing in fresh cooler but dryer air from various air leaks around the property.

    Also try remove the moisture from the surfaces of the conservatory, that helps to break the cycle somewhat.
