Zoo Med Habba Hut

I bought a Zoo Med Habba Hut half log for a 28qt tub where I'm gonna keep a baby boa soon. I threw the sticker away already and I forgot to check what it is made of before I bought it. Does anyone know what it is made of?

This is from Zoo Med's site, but it doesn't say much.

Are Boas prone to disease by any kind of wood like BPs?

Thanks!
