Turns out, it's only sold in more enlightened European countries, not the US.

That might be a good combo. If the fabric can't even set fire with a torch, it will take much longer for the foam to ignite. That's what fireproofing paints and sprays are all about. I'll be testing this very soon, feel free to beat me to it and *document* on YouTube. I've bonded plain polyester fabric to foam boards with epoxy to strengthen them. Works great. Very strong, you can't punch through it (this technique is from the boating world). Could easily take the more common Owens Corning pink foam boards and fabric cover them on both sides. (Forget the paper/aluminum coated polyiso. It's a dead end.) Then you have hard, reinforced foam boards. If you use a little more epoxy, you get a finish that's completely waterproof. Use RAKA UV resistant epoxy and then topcoat with anything. Marine spar varnish...heat treated 100% real Tung oil, real paint...anything for more UV protection. On the interior, use safe paints/dyes, or leave natural...then treat fabric with fire spray. Yes all this costs more money, but it makes the foam boards into real items for long term use. Personally, I'm not into short term party use. I'm looking to push this stuff forward. No tape, no polyiso that soaks up water. -- You received this message because you are subscribed to the Google Groups "hexayurt" group.
