12. The structural insulated panel of claim 1 , wherein the front surfaces and back surfaces further comprise a plurality of holes, respectively, through which the cohesive, insulating filler material extends to engage and adhere to the front skin panel and back skin panel, respectively.

13. A method for constructing a structural insulated panel comprising

forming a fiber-based, flexible, sheet material into a structural member having a corrugated configuration defining

a plurality of front surfaces spaced laterally apart from each adjacent front surface;

a plurality of back surfaces spaced laterally apart from each adjacent back surface and spaced apart in depth from the plurality of front surfaces;

a plurality of chord panels each of which spans between corresponding edges of respective pairs of one of the front surfaces and one of the back surfaces; and

a plurality of chase channels composed of adjacent pairs of the chord panels and a respective one of the front surfaces and a respective one of the back surfaces;

forming a plurality of apertures within each of the plurality of chord panels;

placing a front skin panel made of the fiber-based, flexible, sheet material directly upon the plurality of front surfaces;

placing a back skin panel made of the fiber-based, flexible, sheet material directly upon the plurality of rear surfaces; and

filling the plurality of chase channels with a cohering, insulating filler material such that the cohering, insulating filler material

extends through the apertures in each of the chord panels to substantially equalize a filling pressure within and between the chase channels,

structurally connects the cohering, insulating filler material in adjacent chase channels, and

adheres to the front surfaces, back surfaces, front skin panel, back skin panel, and chord panels to thereby form a monolithic structural bond between the chase channels, the front surfaces and the front skin panel, and the rear surfaces and the rear skin panel;

wherein the structural insulated panel thus formed is load bearing and exhibits structural rigidity.

14. The method of claim 13 further comprising

defining a plurality of recesses within the front surfaces and the adjacent chord panels; and

fitting a cross member defining a channel within the plurality of recesses to extend between lateral sides of the structural insulated panel.

15. The method of claim 14 further comprising

defining a plurality of notches within the cross member configured to interface with the chord panels; and

sliding the cross member into the plurality of recesses such that each notch interfaces with a corresponding chord panel.

16. The method of claim 13 further comprising
