Can somebody point in the direction where I can buy Tyvex or ordinary

Hi,

Try looking for 'vapour permeable membrane' or 'breather membrane'

Ask your local BM (builders merchant) if they have it and for details,
it should have a BBA number which certifes it's use:

the manufacturer will also be able to advise on it's suitability.

BTW Jewson must do it, it features in one of their guides, p27:

also CW Berry do it:
