We have various houses etc made from painted WBP exterior plywood, and I have to say I'm not that impressed with how they're holding up.
This is our two year old goose house for instance:
OK, they've been pretty harsh with it, but even on the bits they haven't managed to gnaw at, some of the outer veneer is starting to bubble up and I doubt the rest will last much past this winter.
So I'm going to have to replace the sides of this and another shed before long, and I also need to put a lid on our new hay racks.
The recycled plastic ply substitutes were discussed recently and didn't get a great writeup, so I'm wondering what else is out there?
It needs to be a strong, waterproof sheet. For the hay racks, box profile cladding would be fine, but I think the animal houses would be too cold if done in metal. If it didn't have to be painted, that would be a bonus, as that's pretty costly and time consuming.
Any ideas folks?
