A glass fiber board product exhibits substantially improved compressive strength and is formed from a laminar mat of glass fiber containing a bonding substance. The mat is processed to rearrange the laminations of the mat so that at least a major portion extends across the thickness of the mat and the mat is then heat-cured and cut perpendicular to the major surfaces of the mat to form strips having opposite longitudinal cut faces. The strips are adhered together in side-by-side relationship to form boards with the cut faces forming opposite major surfaces of the boards. A backing sheet may be adhered to one or both sides of the board. Alternatively, boards cut from the cured mat are adhered together in stacks, which are then cut perpendicular to the boards.
