What is this material and where can I find it?

[Cowboys East]

Hey all,
Thanks for all the suggestions. I checked out vinyl poultry fencing, but the diameter of the holes is a little big. I think I have found out what it is. It is called windbreaker mesh or rockshield mesh. I found it in the UK but not in the US. If you google those two you can see what they look like. I have found some tree guard or hardware mesh that is on the web but Lowes or Home Depot doesn't sell the good stuff. When I find it, and I will, I will let everyone know. I did find some stuff that could be used as a substitute for Epi-Web. Gutter Stuff-Pro, or Gutter-Fill. It is a foam that is put into gutters to keep leaves out. Looks like Epi-Web when you get close. Here again it is difficult to find. Gutter installers usually have it. I believe it is all made out of PET plastic, the same stuff Epi-Web is made of. Bascically recycled plastic bottles.
Thanks,
Neil
