    Afternoon all -

    Apologies if this topic has been done to death already - I can't find it, if it has.

    My Conservatory is glazed in hollow-section Polycarbonate / PVC type stuff, as I'm sure many are. It's blooming freezing. I'm a competent joiner, and can't see any real issues with insulating and boarding it out (ie - from the inside - some studwork against the existing ceiling, a layer of insulating material, and over-boarded with pine cladding or suchlike). HOWEVER - I can see a potential issue with condensation. As I write this, it's dripping a bit on the inside because I just put the heating on. It's not leaking - it's pooling condensation on the ceiling members, which drips down. SO of course - wouldn't want to be sealing that all up with insulation and timber.

    My question is - have any of you guys got any experience of doing this, please, and did condensation turn out to be an issue (and if so, what did you do to solve it? )

    Thanks to all in advance !

    Chris.

    If there is no void then moisture can’t enter to condense.

    That's a good point I suppose - cheers. But surely moisture just exists in the air anyway ? If you're a water molecule, then a cubic centimeter (of "void") counts as quite a large place to condense, surely ?

    Thanks for your comments mate but - can you please share your definition of "void" ? As per my previous - it will be impossible to leave no empty space whatsoever, when packing out and boarding the ceiling - and an airborne water molecule will see a cubic inch as an enormous "void", wouldn't you agree ?

    You either know what you're talking about, but you're too rude / arrogant to bother explaining it properly - or you don't know what you're talking about, and you just like trying to seem "clever". Either way - thanks for your contribution - I'll take it from here.
