TOPIC: Flooring

I have a friend that works for one of the airline...He bringes me dropping of flooring that goes in the large birds. It if fiberglass however it is like cardboard, He has bee bringing me new, however just this weekend said that they have throwing away used boarding out by the dumpster full
He said some sheets are as large as a 5 X 12 in near 3/8, and 1/2 inch thick with notches maybe cut in the side and a few holes for the seat tracks screws

I thinking....flooring for boats...and maybe anything that anyone can think of

He said that if i parked my trailer there in 2 days it may be full...it's a 16 ft flatbed

Any con on using it for flooring

Thanks
