I have over 40 sheets of 4x4 ft tapered foam.
It is used to change a flat roof to a pitched roof. hard to come by.
I paid $10 a sheet. It is half inch on one side and 1 inch on the other side. You put flat foam underneath it in half inch increments to make a tilted surface. Could be used for other things too
I also have some other extra sheet foam.
