The polyiso itself is, well, basically polystyrene for most purposes. The devil's dandruff, however, is *fibreglass.*
Many of the polyiso brands are loaded with the stuff, and I (personally) hate it. It's wicked nasty when cutting with hand tools, and actively quite dangerous when cut with power tools (eyes, lungs etc. - it doesn't seem to cause cancers like asbestos, which is quite surprising, but it's really not good for you.) I cut a chamfered edge H12 and one (or more?) 6' Stretch hexayurts with a craft knife (ceramic keychain sharpener <http://www.google.co.uk/imgres?imgurl=http%3A%2F%2Fecx.images-amazon.com%2Fimages%2FI%2F41y1JMRY18L._SX342_.jpg&imgrefurl=http%3A%2F%2Fwww.artyprofiles.com%2Foutdoor-living%2Fpocket-knife-sharpener%2F&h=420&w=342&tbnid=aRL1TNlasZ71mM%3A&zoom=1&docid=-KPYQiw5WPlVIM&ei=W1HZU5etJ8Sy7Abp64GgAQ&tbm=isch&ved=0CGIQMyg4MDg&iact=rc&uact=3&dur=661&page=4&start=44&ndsp=20> in hand, resharpen with two strokes every foot!), wearing goggles and an N95 mask and gloves, and to this day it was one of the nastiest jobs I've done. I itched for days. Power tools will allow you to convert your entire living room into that kind of mess. Permanently. Thoughts? Don't cut chamfers (aesthetically nice, functionally irrelevant as far as I can tell), cut the boards with a craft or kitchen knife over a tarp, and use a shop vac. I can't stand power saws (grandfather had an accident with one) so there are probably far better ways of doing this, but that's what I've got.
