Condensation Problem with Vinyl Roof Cover

[wheesht]

Hi folks,

this is my first post so thanks for reading it...

I live in a yurt imported from Mongolia to England. Where we live it rains a fair amount of the time.

The problem we have is condensation forming directly under the Vinyl cover. We don't have Reflectix-type

insulation

but felt and extra carpet underlay which contains felt and some man-made elements.

The yurt has a Vinyl roof cover which is quite rare round here, most people going for full felt and canvas covers.

The wall consists of felt and canvas (no vinyl).

We cook inside the yurt on butane gas so there are considerable water vapours formed there.

I have seen

Pacific Yurts

for example using Vinyl covers and reflectix-type

insulation

. I would like to do the same and wonder how to go about it.

Do I just put the reflectix insulation directly onto the outside of trellis/roof poles and then the vinyl cover onto that?

Can I keep/Will I still need the felt insulation for extra cosiness or will it still affect the dewpoint and still cause condendsation? It gets down to about 14 Farenheit in winter here, the yurt is heated with a woodburner.

Can I replace the canvas wall cover with Vinyl too? The canvas is rotting on the north side and although i've tried scrubbing and waterproofing, it keeps coming back.

Will Reflectix as a non-breathable insulation make condensation form inside the yurt?

Can I keep the thin white cotton cover as the very inside layer (but still outside the trellis and poles) as it looks better than foil?

I think that's all for now. I'd be very grateful if anyone's read this far to hear your thoughts and suggestions

Many thanks
