Building material that dissolves in water and same time flame retardant? Answered
Hello everyone! I have a problem that I've been working on for a while.
I need to instal a mobile unit in the sprinklered mall. The Fire Marshall told us that the mobile unit has to be installed with sprinklers or with a ceiling that dissolves in the water AND flame retardant in the same time. Installing sprinklers is not an option. Also, the ceiling has to be about 8x20.
I need to know if it's possible and if yes, what materials would work?
I would really appreciate any help! And If it's possible even only in theory, please let me know.
