It’s super heavy. I had to pay my contractor to build 3 vertical support beams and 2 long horizontal beams strong enough to support the weight of 2 curtains.  He installed hooks along the top to hang the curtains. 
When I folded it up the bottom hooks do not match the top holes and the sides do not meet each other either. 

Otherwise the quality looks heavy and thick and I’m hoping it will keep my outdoor patio warm from the wind and rain this winter.
