Are there any alternative uses for PIR rigid foam?
I got way more than this photo shows and don't really want to land fill it.
Other than jamming it in little gaps as a secondary insulation I'm at a lost what to do with it.
Is it fire-proof?
Is it heat proof?
Can I carve it and cover in clay ?
Can I use it for moulds?
Does hot glue stick to it or melt it?
Does it give off fumes when hot/burning?
Is it petrol resistance?
Can I use it for polishing?
Can I grind it up and use it to fill small gaps?
Can I mix it into cement?
