Wood vs metal auto coop door - For winter

[Jen18945]

I did a search but couldn't really find anything that addressed insulation of coop doors.
Live in NH- our winters can get below freezing and ice storms are common. Summers have started to get extremely hot as well, sometimes reaching 100 degrees.
I was looking at 3 coop doors- Adore; Eglet and the Coop Tender.
The Coop tender is rated for freezing and it's made out of wood. I'm worried about the wood rotting in the snow, rain etc. Yet, what would insulate better against the temperatures?
I have to get something sturdy, because we do have bears that come through my yard and I live in a wooded area with predators.
I looked at DIY- but my electronic knowledge is not great ( eventhough my Grandfather tried to teach me )
Thanks!!

I don't think the amount of insulation is going to make much difference, since this is only the pop door and not a big area.

I would just ignore that detail, and choose the one that makes sense in other ways (predators are probably the biggest issue, with rotting or rusting beng a lesser issue but still maybe worth considering.)

I use Brinsea extreme and made my own door from plywood- about 3 lbs. I rarely have uses with it freezing shut.
Winter is rough here- lots of snow, temps as low as -30.

All coop door, especially auto doors, should be protected from rain/snow/ice.

Only thing to keep bears at bay is HOT wire.
