Foam insulation boards - safe to use in spider room?

[fcat]

I'm looking to insulate my spider room by affixing foam insulation boards to the two exterior walls in my spider room. One of them is on the west side and gets full sun.

Is this a terrible idea? I read that XPS extruded polystyrene is considered non toxic, but read the rest is going to give me cancer, only harder.

The shelves will be pushed against these boards like they were the walls, and paired with my affinity for air circulation, no one will be spared from these boards, not even the rest of the house.


What do you guys think?

Nothing is tested for our pets. Do what works for you. They aren’t coming in contact with it.

Have you looked into that foam blow-in insulation? Much less intrusive, though I can't speak to its relative toxicity...

This material is commonly used in constructing terrarium backgrounds for bioactive enclosures that contain dart frogs. If it's amphibian safe, then it's tarantula safe. In fact, I've used it in many applications for my own collection. In addition to using it to create backgrounds, I've also used it to create foam rocks for my Aphonopelma enclosures to both reduce the weight of the enclosure and provide them a rock to dig under as they naturally do in the wild.

Yes, for the attic though. I'm hoping I don't have to go too far into the attic to complete that project as I am sized right for the job. I'd be more worried about the existing insulation than what I'm blowing in (cellulose). And I bet that has to be done to reap any benefit from my wall project

To my understanding the damage is done in the manufacturing. The more I've read about this and all the other materials in building a house, we are all doomed
