Abstract:
1. A laminated insulated timber residing in a three-dimensional coordinate system defined by an X direction, a Y direction, and a Z direction wherein said X direction defines a timber width of said laminated insulated timber, said Y direction defines a timber height of said laminated insulated timber and said Z direction defines a timber length of laminated insulated timber, said laminate insulated timber comprising: a first plank defined by a first plank width extending in said X direction, a first plank height extending in said Y direction, and a first plank length extending in said Z direction, said first plank length is greater than said first plank height, said first plank height is greater than said first plank width; a second plank defined by a second plank width extending in said X direction, a second plank height extending in said Y direction, and a second plank length extending in said Z direction, said second plank length is greater than said second plank height, said second plank height is greater than said second plank width; a third plank defined by a third plank width extending in said X direction, a third plank height extending in said Y direction, and a third plank length extending in said Z direction, said third plank length is greater than said third plank height, said third plank height is greater than said third plank width; a fourth plank defined by a fourth plank width extending in said X direction, a fourth plank height extending in said Y direction, and a fourth plank length extending in said Z direction, said fourth plank length is greater than said fourth plank height, said fourth plank height is greater than said fourth plank width; a fifth plank defined by a fifth plank width extending in said X direction, a fifth plank height extending in said Y direction, and a fifth plank length extending in said Z direction, said fifth plank length is greater than said fifth plank width, said fifth plank width is greater than said fifth plank height; a sixth plank defined by a sixth plank width extending in said X direction, a sixth plank height extending in said Y direction, and a sixth plank length extending in said Z direction, said sixth plank length is greater than said sixth plank width, said sixth plank width is greater than said sixth plank height; an insulation member that is composed of a material that has a greater thermal insulation coefficient than said planks, said insulation member essentially surrounded in said Y direction and said X direction by said second plank, said third plank, said fifth plank and said sixth plank; said fifth plank and said sixth plank are interposed between said second plank and said third plank; said fifth plank and said sixth plank abut against sides of said second plank and said third plank wherein said sides of said second plank and said third plank extend in said Y direction; said second plank and said third plank extend beyond said fifth plank in a positive direction in said Y direction and said fifth plank extends beyond said first plank and said fourth plank in said positive Y direction both forming tongues; said sixth plank extends beyond said second plank and said third plank in a negative direction in said Y direction and said first plank and said fourth plank extend beyond said sixth plank in said negative Y direction both forming grooves; means for fixedly attaching said first plank to said second plank and said second plank to said fifth and said sixth planks and said fifth and said sixth planks to said third plank and said third plank to said fourth plank wherein said widths of said first plank, said second plank, said third plank, and said fourth plank essentially define said tongues and said grooves of said insulated laminated timber.
