A construction panel is provided comprising a core of expanded or foamed polymeric material embodied between two major face members of resin reinforced with glass fibers. The side walls of the panel comprise pultrusion angle members which are encapsulated in the panel within the major face members. Elongated U-shaped pultrusion reinforcing members may be disposed within the panel to provide reinforcement and a channel for the receipt of wires, pipes, or to act as heating, air conditioning or vacuum cleaning ducts. The glass fibers used to reinforce the major face members are in multidirectional orientation and have portions extending into the interior of the panel to provide a mechanical and chemical bond between the core and the major face members. The pultrusion members may be made from resin reinforced with continuous strands of glass fibers in unidirectional orientation, and are preferably prestressed.
