Waterproofing Canvas

[Yurts_latvia]

Hi all at the forum!


First post from us. We're making yurts in Latvia and investigating different options for a good waterproof roof.


We don't get too much rain here in Latvia - in winter it's mostly snow and in summer it's just the occasional (but heavy!) thundery downpour.



We want to keep the roof pitch as slight as possible to improve

heating

capacity during winter. Our first yurt frame is set at 25 degrees.


We want to use natural materials where possible, so cotton canvas is the obvious choice. If it is untreated, will a waterproofing treatment such as Nitwax Cottonproof be enough?

Would others be so kind as to share their experiences with roof materials, treatment and roof pitch to stay dry?




With many thanks!
