depends on which side is placed towards the ground,as its main use is as a replacement for roofing felt on houses .
the outer side repels moisture but the inner face lets it through to prevent condensation similar to goretex.
thats great thanks huskyman.........is it true that the writing needs to be face down for it to be waterproof ?
I don't know, the sheet of Tyvek I have has no writing on it.
It seems the same on both sides, I got it from TarpTent, to fit my Scarp 1.
It's slightly thicker than greaseproof paper, sort of feels the same, but no matter how much I try I can't rip it.
