Abstract
A molded construction product, having one or more walls and an inner core section, including a composition matrix having a resin system, a catalytic agent, and filler compounds for forming the walls; a foam core system for forming the inner core section, a curing agent and a drying agent. The resin system is for providing mechanical and physical characteristics of hardness and rigidity to the exterior walls of the molded product. The catalytic agent is for activating the reaction for the polymerization of the resin system. The filler compounds for reinforcing the walls. The foam core system is for producing the inner core section having three-dimensional cross-linking and a core density of 3.5 pounds per cubic foot. The curing agent is for cross-linking of polymers within the resin system for forming the exterior walls to be hard, rigid, and infusible. The drying agent is for drying and binding of excessive moisture within the composition. A structural reinforcement support system is provided for reinforcing the structural integrity of the composition. A locking system is provided for joining one or more of the molded products.
