Cotton vs Polyester vs PVC

[Yurts_latvia]

Nice feedback guys!



So Bob sounds like your poly-cotton painters tarps for walls weren't treated at all - did rain ever come through? Or did they ever go moldy?


TS, thanks a lot for your insights on hemp. Great to understand a bit more about its virtues.


Do you think if was waterproofed it would also hold up well as an outer cover for several years?


My current thinking of my ideal would be to have a single breathable cover like that for the summer (I just love the simplicity, breathability and light penetration of single layer) whilst perhaps the reflective insulation and pvc would be a good bet for the colder months.



I think having a pvc cover backup is a nice touch also if there's ever a problem with a more delicate material - you can be sure that stuff is pretty bomb-proof!


+ I wonder about woven materials under snow? Sheeting off drops of rain is one thing but being impermeable to a slowly melting foot of snow - that seems like a tall order!



Thanks all of you
