Abstract
A method may include placing a bottom facer on a conveyor, placing a core layer on the bottom facer placing a top facer on the core layer, and pressing the bottom facer, the core layer, and the top facer in a hot press to form a panel, wherein the hot press causes the bottom facer to shrink relative to the top facer, introducing a warp into the panel such that, when installed, the warp compensates for an installation warp and the panel is flat upon installation.

A coverboard comprising:
- a top facer;
- a core layer;
- a bottom facer, wherein the coverboard is formed in a hot press which causes the bottom facer to shrink relative to the top facer, introducing a warp into the coverboard such that when installed, the warp compensates for an installation warp such that the coverboard is flat upon installation.
A coverboard comprising:
- a top facer;
- a core layer;
- and
