A fabric-surfaced fiber board having pressed and non-pressed portions. The board includes a low density fiber board composition having a re-activatable binder therein and having a fabric bonded thereto to form a laminate therewith. The laminate has peripheral portions wherein said fiber board composition has been compressed and reformed to have a reduced height, a higher density and a greater strength as compared to the non-pressed portion of the board.
