The location of the yurt is on the Atlantic coast of Portugal. The part of the coastline is known for its hot and dry summers and pretty wet winters. We also get some severe storms once in a while. The yurt itself is positioned directly with influx of these weathers with no natural protection from wind and rain. 

In the pre-order process I was asked regarding rain and I said yes – heavy rain in winter from November until February.

Thus we agreed on a PVC cover (as I thought). If you research yurts you can see many of them with a rigid PVC cover.

Some typical properties of PVC are durability, good stiffness, good impact resistance and excellent chemical resistance. In addition they are extremely waterproof. 

But what I received was a simple plastic cover comparable to a transparent plastic bag in shape of the yurt. 

In the construction process I decided to not install the plastic layer in order to prevent mold 

After 2 month of collecting quality data I made this small clip regarding water proofing. The essence is that the yurt is some kind of water resistance but it is not water proof. That means after heavy rain the yurt got wet in the area of the drip board and above. The inside walls feel super cold and humid and after drying off leaving an ugly stain.
