What type of plywood

[Chickylove12]

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?

Treated plywood is not needed if you paint the coop as most people do. I use a type of fiberboard called Knotty Barnside that stuff works great and it is only $22USD a sheet.

T-111 and Plytanium and Hardiplank is all roughly $25 a sheet at the local Home Depot and is rated for exterior use.

I'm a big proponent of Advantech. I used the sub floor for my entire coop. The zip system is good if your going to cover the outside with siding. I plan on painting mine.
I live in the snow belt of Ohio. I didn't get the coop painted before winter and you can barely tell it spent 6 months in moisture.
Nov. 3, 2018. I took this when I finally got a door on the front. By the date you can see why I didn't paint...

It's not swollen and waterlogged or falling apart. The color changed a bit from all the weather but it's not damaged at all.

eta: I'm dealing with flooding. Water is leaking in under the base plate on one side of the coop, and the Advantech is still not saturated.

I looked it over. Thanku..but it seems to promote open poultry houses..I have too many predators.

I ended up getting 3/4 inch treated CDX plywood that was noted for extreme weather conditions. $37 A sheet at Lowe's in odensberg. That will be our flooring anyway to start with up on cinder blocks.

The "open" part is covered with hardware cloth, but if you have bears all bets are off.
