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 method comprising:
- 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 thermally fuse a mixture of paper fragments and plastic fragments in the core layer to form a panel such that the bottom facer shrinks 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.
