I live in Canada.. but the states is just a stones throw away from me. We have snowy cold winters and hot summers. I have heard that advantech plywood is good to use when building coop ..only available in states..and close to $40 A sheet. When I read the write up on it..it says that it's not been treated. So how can I use it for exterior walls..roof...floor? Then I read about this zip plywood? Is it more sensible to use regular exterior treated plywood?
