Bee box insulation

Hello Permies! I live in NW montana.
My friend is a dealer for foam insulation for your bee boxes. They are pre made to whatever that correct size is and he showed me one today - really tough stuff. Anyways I in no way benefit from this but this guy has been doing concrete all his life (my greenhouse subcontractor) and he could use a break or two! If anyone would like to contact him, message me and I'll reply with his phone number 406 or email. I just thought it was really serendipitous with him showing me the block insulator and Paul's new bee video. Hope all is well with this community, i have an account but I usually just lurk. God bless!

What sort of foam ? Many off gas stuff bees would not like . I know I wouldn't . Extra thick wood or cork may be better .

Or hay/straw bales.

It's a white foam that is super strong, it does not off gas. I bought blue dow board early in one of our projects and he made me return it for the offgasing issues you describe. Almost 100 percent sure that this foam would not do that. I'll ask him for the name next time i see him. Interesting side-note Canada has figured out the chemical byproducts in things like blue board and banned them in their country...

White Foam is ? Polystyrene ?
Blue foam is ?.....

It may depend on the manufacturer. According to this:
BLUE RIDGE FIBERBOARD products consist of pre-consumer content (wood chips). The binding agent used in the making of BLUE RIDGE FIBERBOARD fiberboard is also an all-natural product, consisting of vegetable starch containing no added formaldehydes.

Sorry the blue foam I was describing Dow blue board, a nice evil conglomerate. I talked to my concrete fellow, the foam is EPS so it is not going to off-gas or bleed, it's safe, but I know people of like mind in this forum might not love foam idea... I would use it to protect things in the winter
