I am considering using metal roofing painted white and facing the 'wrong' way on my inside walls. Its a 40X40 pole barn
White to reflect light, metal to reduce the possibility of fire damage and putting it up with the flat side out so that shelves will fit flat to minimize the chance of stuff falling off the back of the shelves.
The kind of metal this company calls Great Rib
