Abstract

This is a new method for the construction of waterproof insulated products, by creating individual insulation-filled compartments without stitching through the outer shell of the product. This invention further provides methods for constructing waterproof insulation products without requiring the attachment of the individual compartments to the inner lining.

Claims (15)

1. An insulation product comprising:

an outer shell; an inner liner shell; one end of a netting attached to one of the shells to form compartments; insulating material added to the resulting compartments formed in the space between the shells; the other end of the netting bonded to only the netting of an adjacent compartment to enclose the insulating material and create an air blanket between the compartments and one of the shells.

2. An insulating product according to claim 1 , wherein the netting is comprised of polytricot and cotton to withstand a temperature up to 160° C. and which is attached directly to a shell typically using seam tape.

3. An insulating product according to claim 2 , wherein the insulated product is used to create insulation for piping, buildings, housing and structures.

4. An insulating product according to claim 2 , wherein the netting is attached to the outer shell with the air blanket formed between the compartments and the inner shell.

5. An insulating product according to claim 4 , wherein the insulating material is down.

6. An insulating product according to claim 4 , wherein the insulated product is a sleeping bag.

7. An insulating product according to claim 4 , wherein the insulated product is a garment and other clothing.

8. An insulating product according to claim 3 , wherein the insulated products is a blanket.

9. An insulating product according to claim 4 , wherein the outer shell is waterproof.

10. An insulating product according to claim 1 wherein the netting is attached to pieces of fabric which are bonded to the inside of either the outer or inner shell.

11. An insulating product according to claim 10 wherein the netting is attached to the outer shell with the air blanket formed between the compartments and the inner shell.

12. An insulating product according to claim 11 wherein the insulating material is down.

13. An insulating product according to claim 11 wherein the insulating product is a sleeping bag.

14. An insulating product according to claim 11 wherein the insulating product is a garment.
