yeah, because 'Safety is no accident'
Edit-
If anyone still cares, the results are in!
Well, under an open candle flame it smolders then lights up at an average(?) rate, kinda like waxed paper or heavy cardboard.
In the more realistic scenario we had put a 100 watt light to it and didn't even get pliable after 2 minutes...
So, perhaps i was a tad over-cautious, but mostly bcoz of the warning lable it had. Without a flash-point to go on it gives the impression the stuff was inflammable, i mean better safe then sorry and have no reptiles or home in the end, right? In conclusion i see nothing wrong with this particular plastic type now, I'll go with it, I just had to see for myself.
Thanks for the imput and for listening everyone, cheers!
