INSL is great. It can maintain temperature and pressure and can hold things like LOXY and LN2 without vaporizing them. There's just one problem though. It's flammable.
I guess some of you can tell from my other posts that I'm a rocket freak. I'd like to be able to contain LOXY as an oxidizer without its container combusting.
you could try HWSC and TTAN layers. like this

Where "T" is TTAN and "H" is HWSC obviusly.
