Boxed netting insulation system for roof deck
Insulation systems that provide insulation cavities below trusses of residential roofs. The insulation systems are configured to provide insulation material directly below bottommost surfaces of the roof trusses. The insulation systems may include insulation support material that provides insulation pockets below bottommost surfaces of roof trusses. Insulation support material may include side panel segments and span segments. The insulation support material may be attached to the roof trusses or sheathing panels from below the roof trusses and sheathing panels.

a single span segment connected to the single side panel segment and having a width that substantially matches the predetermined spacing of the structural members;
a tab at a transition from the single side panel segment to the single span segment;
wherein the tab of a first of the interconnecting portions is connectable to the single span segment of a second of the interconnecting portions to provide an insulation cavity;
wherein the side panel segments and the span segments define insulation cavities with pockets located directly under the bottommost surfaces of the wooden structural member, and insulation disposed in the pockets directly under the bottommost surfaces of the wooden structural members.
2. The insulation support material of claim 1 wherein the single side panel segment and the single span segment of each interconnecting portion are made from a flexible material that comprises a mesh or a plastic film.
3. The insulation system of claim 1 wherein at least one of the single side panel segments is made from a rigid material and at least one of the single span segments is made from a flexible material that comprises a mesh or a plastic film.

5. The insulation system of claim 1 wherein the single span segment of each interconnecting portion is made from an air barrier material.
6. The insulation system of claim 1 wherein the single side panel segment of each interconnecting portion is made from an air pervious material, a breathable material, an open netting, or a mesh.
7. The insulation system of claim 1 wherein the single span segment of each interconnecting portion is made from a vapor retarder material and wherein the single side panel segment of each interconnecting portion is made from an air pervious material, a breathable material, an open netting, or a mesh.
8. The insulation system of claim 1 wherein the single span segment of each interconnecting portion is made from an air barrier material and wherein the single side panel segment of each interconnecting portion is made from an air pervious material, a breathable material, an open netting, or a mesh.
9. An insulation system comprising:
wooden structural members that are spaced apart;
sheathing panels disposed on top of top surfaces of the wooden structural members;
insulation support material comprising:
side panel segments attached to and extending past bottommost surfaces of the wooden structural members;
span segments supported below bottommost surfaces of the wooden structural members by the side panel segments; and
wherein each span segment is connected to only one side panel segment;
wherein the side panel segments and the span segments define insulation cavities with pockets located directly under the bottommost surfaces of the wooden structural members; and
insulation disposed in the pockets directly under the bottommost surfaces of the wooden structural members.
10. The insulation system of claim 9 wherein the side panel segments and the span segments are made from a flexible material that comprises a mesh or a plastic film.
11. The insulation system of claim 9 wherein the span segments each have a width that substantially matches the predetermined spacing of the trusses wooden structural members.
12. The insulation system of claim 9 wherein the side panel segments are made from a rigid material and the span segments are made from a flexible material that comprises a mesh or a plastic film.
13. The insulation system of claim 9 wherein the span segments are made from a vapor retarder material.
14. The insulation system of claim 9 wherein the span segments are made from an air barrier material.
15. The insulation system of claim 9 wherein the side panel segments are made from an air pervious material, a breathable material, an open netting, or a mesh.
16. The insulation system of claim 9 wherein the span segments are made from a vapor retarder material and wherein the side panel segments are made from an air pervious material, a breathable material, an open netting, or a mesh.
17. The insulation system of claim 9 wherein the span segments are made from an air barrier material and wherein the side panel segments are made from an air pervious material, a breathable material, an open netting, or a mesh.
18. The insulation system of claim 1 wherein the wooden structural members are angled.
19. The insulation system of claim 1 wherein the wooden structural members are truss chords.
20. The insulation system of claim 1 wherein each interconnecting portion further comprises a second tab at a free end of the single span segment.
21. The insulation system of claim 1 wherein a distance between the roof sheathing and the material of the single span segment of each interconnecting portion is substantially uniform.
22. The insulation system of claim 20 wherein the tab at the transition from the single side panel segment to the single span segment of the first interconnecting portion is connectable to the second interconnecting portion to provide an insulation cavity.
23. The insulation system of claim 9 wherein the wooden structural members are angled.
24. The insulation system of claim 9 wherein the wooden structural members are truss chords.
25. The insulation system of claim 1 wherein the single span segment of each interconnecting portion is made from an air pervious material, a breathable material, an open netting, or a mesh.
26. The insulation system of claim 9 wherein the span segments are made from an air pervious material, a breathable material, an open netting, or a mesh.
