Help with styrofoam inside enclosure

[beardy27]

So I am a bit worried since I have read that foam gives off fumes when heated. I just built my first rock wall and basking area from left over styrofoam found in packaging. I did about 3 layers of grout and 2 of mod podge. However the whole back and bottom are just bare foam in order to save on material and weight. Will this bare foam cause fumes to come out if left lime that? Or do I really need to cover it?

Anyome? I don't want to put it in my enclosure until I am sure it's safe.

I don't think the enclosure will reach temps needed to cause the foam to start burning and producing harmful fumes. A lot of people use foam as a backdrop in their enclosures.

Ok thank you for the reply, I know it should be fine on the parts that I covered with grout and mod podge but I was just wondering about the parts that I did not cover such as the back and bottom sides that are not visible or accesible to the dragon.

It shouldn't be a problem temp wise but insects are pretty good and getting up and into things and can chew up the foam.

I don't plan on letting crickets loose in his terrarium so I guess I should be fine. Thank you all!
