Depends on your wrapper. If I was sending an installer I would build it as one complete panel, then tile it in my rip into 4 even panels with a 1.5 inch overlap. It'll make for an easier install. Then again I'm not the installer, I'm sending someone to install and want to give him all the chance for success. Just my 2.
