I have and do use scaffold debris netting. It has very fine mesh, stops the cabbage whites ;D if done up properly, they can get through the smallest of gaps, it allows watering to be done in situ, and lasts for ages.
I get mine off ebay, about £35 for 50x2mtrs inc. delivery.
Also available in different colours. You can have black, green, blue, red or yellow. Brightens up some plots. 8)
I would use it for fruit cages, currently covering my strawberry baths, or any framework that needed protection from birds etc...
p.s I call them strawberry baths because thats what they are, baths.
