Abstract

An insulation system includes roof sheathing panels, spaced apart structural members, a first insulation material, and a second insulation material. The first insulation material is disposed between pairs of the spaced apart structural members. The second insulation material is disposed across the spaced apart structural members and the first insulation material, such that both the spaced apart structural members and the first insulation material are covered by the second insulation material.

Claims

1. An insulation system comprising:

roof sheathing panels that extend upward at an angle away from an eave toward a ridge;

spaced apart structural members that extend upward at an angle away from the eave toward the ridge, wherein the spaced apart structural members support the roof sheathing panels, wherein the spaced apart structural members each include a top face that faces toward the roof sheathing panel and a bottom face that faces away from the roof sheathing panels;

a first insulation material disposed between pairs of the spaced apart structural members, wherein the first insulation material has a bottom face that is substantially flush with the bottom faces of the spaced apart structural members;

a second insulation material disposed across the spaced apart structural members and the flush first insulation material, such that both the spaced apart structural members and the first insulation material are covered by the second insulation material.

2. The insulation system of claim 1 wherein the spaced apart structural members are spaced apart truss chords.

3. The insulation system of claim 1 wherein the first insulation material substantially fills a space between the top and bottom faces of the spaced apart structural members.

4. The insulation system of claim 1 wherein there is a vent space between the first insulation material and the roof sheathing panels.

5. The insulation system of claim 1 wherein the second insulation material has a substantially planar lower surface.

6. The insulation system of claim 5 wherein the planar lower surface of the second insulation material is maintained by reinforcing ties.

7. The insulation system of claim 1 wherein the second insulation material is held against the first insulation material by fasteners that extend into the spaced apart structural members.

8. The insulation system of claim 1 wherein the second insulation material has a substantially uniform thickness.

9. The insulation system of claim 1 wherein the second insulation material comprises loose fill insulation in a container.

10. The insulation system of claim 1 wherein the second insulation material comprises an insulation batt.

11. The insulation system of claim 1 wherein the second insulation material extends across three or more of said spaced apart structural members.

12. The insulation system of claim 10 wherein the insulation batt extends across three or more of said spaced apart structural members.

13. The insulation system of claim 1 wherein the second insulation material is held against the first insulation material by fasteners that extend through the second insulation material and into the spaced apart structural members.

14. The insulation system of claim 1 wherein the first insulation material comprises an insulation batt.

15. The insulation system of claim 1 wherein the first insulation material comprises an insulation batt and the second insulation material comprises an insulation batt.

16. The insulation system of claim 15 wherein the first insulation batt is connected to the second insulation batt.

17. An insulation system comprising:

roof sheathing panels that extend upward at an angle away from an eave toward a ridge;

spaced apart structural members that extend upward at an angle away from the eave toward the ridge, wherein the spaced apart structural members support the roof sheathing panels, wherein the spaced apart structural members each include a top face that faces toward the roof sheathing panel and a bottom face that faces away from the roof sheathing panels;

first insulation batts disposed between pairs of the spaced apart structural members, wherein the first insulation batts have a bottom face that is substantially flush with the bottom faces of the spaced apart structural members;

second insulation batts disposed across the spaced apart structural members and the flush first insulation batts, such that both the spaced apart structural members and the first insulation batts are covered by the second insulation batts.

18. The insulation system of claim 17 wherein the first insulation batts are compressed between pairs of the spaced apart structural members.

19. The insulation system of claim 17 wherein the spaced apart structural members are spaced apart truss chords.

20. The insulation system of claim 17 wherein the first insulation bats substantially fill a space between the top and bottom faces of the spaced apart structural members.

21. The insulation system of claim 17 wherein the second insulation batts have a substantially planar lower surface.

22. An insulation system comprising:

roof sheathing panels that extend upward at an angle away from an eave toward a ridge;

spaced apart truss chords that extend upward at an angle away from the eave toward the ridge, wherein the spaced apart truss chords support the roof sheathing panels, wherein the spaced apart truss chords each include a top face that faces toward the roof sheathing panel and a bottom face that faces away from the roof sheathing panels;

a first insulation material disposed between pairs of the spaced apart truss chords;

a second insulation material disposed across the spaced apart structural members and the first insulation material, such that both the spaced apart structural members and the first insulation material are covered by the second insulation material.

23. The insulation system of claim 22 wherein the first insulation material substantially fills a space between the top and bottom faces of the spaced apart truss chords.

24. The insulation system of claim 22 wherein there is a vent space between the first insulation material and the roof sheathing panels.

25. The insulation system of claim 22 wherein the second insulation material has a substantially planar lower surface.

26. The insulation system of claim 22 wherein the planar lower surface of the second insulation material is maintained by reinforcing ties.

27. The insulation system of claim 22 wherein the second insulation material is held against the first insulation material by fasteners that extend into the spaced apart truss chords.

28. The insulation system of claim 22 wherein the second insulation material has a substantially uniform thickness.

29. The insulation system of claim 22 wherein the second insulation material comprises loose fill insulation in a container.

30. The insulation system of claim 22 wherein the second insulation material comprises an insulation batt.

31. The insulation system of claim 22 wherein the second insulation material extends across three or more of said spaced apart structural members.

32. The insulation system of claim 31 wherein the insulation batt extends across three or more of said spaced apart structural members.

33. The insulation system of claim 22 wherein the second insulation material is held against the first insulation material by fasteners that extend through the second insulation material and into the spaced apart structural members.

34. The insulation system of claim 22 wherein the first insulation material comprises an insulation batt.

35. The insulation system of claim 22 wherein the first insulation material comprises an insulation batt and the second insulation material comprises an insulation batt.

36. The insulation system of claim 35 wherein the first insulation batt is connected to the second insulation batt.
