Ha Guys, I'm headed out to get some 1x material and plywood for my attic layout. I 'll have 4 sections that are 1'x8' and two corners 1'x4'x3'. Sinse the sections are so narrow, I was thinking of using 3/8" plywood. I also cosidered using the thick foam instead, however it's not readily availible here in the South, all they sell is 1/2". What do you guys think?
