A burning question.

Following up previous comments, I took a blowlamp to a piece of Celotex. A soft surface flame develops immediateky, but self extinguishes within a couple of seconds. Trying to reignite a charred section only results in a red glow of the material. It doesn't even melt.
I would say it's as safe as you could expect from this type of material.
Just pissing about. I like that.
