Abstract
A method of making tough, water-proof building panels depositing a first fiber-rich layer onto a support, the first fiber-rich layer having a width defined by first and second side edges, a length direction, and a top surface; placing foam blocks on the first layer, lengths of the foam blocks extending generally between the first and second side edges of the first fiber-rich layer; depositing a second fiber-rich layer onto the combination of the first fiber-rich layer and the foam blocks, thereby to develop an uncured precursor to the building panel; and curing the uncured precursor to the building panel thereby to make a generally rigid structural building panel.
