Question by vipergtx500: plywood over insulation in attic?
There is an unknown R value of insulation in my attic and i want to lay plywood up there so I can store things. What is the best/most economical way of doing this. I will be doing all the work myself.

if the joists are all about14″ or so apart and you will be mostly crawling around you can use 1/2″ plywood the grain ….if access is tight you may have to cut the boards into strips….. i would start in the center closest to the access and work myself out from there…..you can leave gaps near the roof line….. probably just use nails dont even need to many just enough so the boards dont move around…watch for wires…the strips of ply wood need to lay across the joists
