Im looking at purchasing another vivarium as a project and turning it into a "live" habitat for my red eyed tree frogs. I have never done this before, so want some tips/advice if possible. I have looked around this fantastic application called the world wide web, aka the internet and seen some brilliant guides and they all refer to the 'foam' which helps hold the wood and plants pots in place for the background. Then you add the black silicone so that you can stick on the eco earth etc.

Whats the name of this foam? I believe from research its called 'great stuff', but want to be sure this is ok for vivarium use? Providing its left out to air for a couple of days.

Will the foam support small pieces of drift wood etc, I'm only planning on testing this with a 30cm (width) x 30cm (depth) x 45cm (height) and intend to cover the back wall and one side wall with a couple of small pieces of wood and 1/2 small plant pots for a couple of dwarf bromeliads / creeping fig / fern. I will be keeping the other wall free for my heat pad.

Will a well made great stuff background need replacing, or will give many years service. Im guessing it can withstand the humidty etc required.
