Lightweight structural panel

A structural panel configured for use in building installation comprising:

• a three-dimensional space frame assembly, wherein the space frame assembly comprises:
• at least two longitudinal sides;
• at least one lateral side;
• a plurality of sinusoidal support members arranged in a lateral direction;
• and
• a plurality of opposing reinforcing elements arranged in a longitudinal direction;
• a pair of truss members, wherein one truss member in the pair is attached to each longitudinal side of the space frame assembly;
• a pair of stud members, wherein one stud member is attached to each longitudinal side of the space frame assembly and a corresponding said truss member as a bracing system, each stud member comprises a plurality of apertures located along a longitudinal length thereof;
• a foam layer which is provided throughout the space frame assembly, truss members, and stud members;
• a plurality of first cavities, wherein each first cavity lines up with a corresponding said aperture and extends in the lateral direction from the one stud member to the other stud member;
• and
• a plurality of second cavities, wherein each second cavity extends in the longitudinal direction through a body of the panel;
• wherein the structural panel possesses load bearing capacity and the truss members, sinusoidal support members, stud members, and reinforcing elements provide structural integrity and load bearing capacity independent of the foam layer.
