Abstract

A sound insulating space board apparatus (10) comprising an evacuated cellular array (14) sealingly engaged to an upper (18) and lower (19) planar member, wherein each of the planar members are provided with a layer of air impervious material (100), and each of the individual evacuated cells (15) in the cellular array (14) define a nine sided polyhedron configuration.

Claims

1. A sound insulating space board apparatus comprising:

an upper planar member provided with a layer of air impervious material on its lower surface;

a lower planar member provided with a layer of air impervious material on its upper surface; and

,

a cellular array sandwiched between the air impervious material on said upper and lower planar members;

wherein the upper and lower surfaces of said cellular array are covered with layers of air impervious material and the cellular array comprises a plurality of reciprocal integral cells comprising like cells and unlike cells wherein each cell has a nine sided polyhedron configuration.

2. A space board apparatus as in claim 1 wherein the like cells are disposed diagonally with respect to adjacent like cells, and are disposed side to side with respect to adjacent unlike cells.

3. A space board apparatus as in claim 1 wherein both sides of said cellular area are covered with a layer of air impervious material.

4. A space board apparatus as in claim 1 wherein the cellular array is sealingly engaged with the upper and power planar members and the individual cells of the cellular array are evacuated.

5. A sound insulating space board apparatus comprising:

an upper planar member comprising at least one layer of air impervious material;

a lower planar member comprising at least one layer of air impervious material; and

,

a cellular array sandwiched between said upper and lower planar members and comprising at least one layer of air impervious material;

wherein, the cellular array comprises;

a plurality of individual cells wherein each cell has a nine sided polyhedron configuration.

6. A space board apparatus as in claim 5 wherein adjacent cells are arranged in a reciprocal fashion with respect to one another.

7. A space board apparatus as in claim 6 wherein the individual cells are evacuated and sealingly engaged relative to said upper and lower planar members.
