Insulatable, insulative framework apparatus and methods of making and using same
A building framework is disclosed herein comprising a first structural member, a second structural member, and a third structural member disposed between the first and second structural members, a first web member connecting the first and third structural members in a spaced apart relationship, and a second web member connecting the second and third structural members in a spaced apart relationship. The first web member is positioned relative to the second web member such that the shortest distance between the first web member and second web member is greater than or equal to 5 times the thickness of the third structural member. Additional products, systems, and methods also are disclosed.

a second web comprising a second plurality of web members each connecting the second structural member to the third structural member,
a set of metric paths, each metric path in the set being defined by a shortest path along which energy can flow through the framework between a first point on the first structural member and a second point on the third structural member, the energy flowing between the first structural member and the second structural member through at least one web member,
each metric path in the first set of metric paths being characterized by
a range, R
a path length, L
and a rangewise indirectness I R wherein (L/R)−1=I R ,
wherein an average rangewise indirectness for the set of metric paths is greater than 0.05.
2. The framework of claim 1 configured such that the average rangewise indirectness is greater than 0.10 for the set of metric paths.
3. The framework of claim 1 , wherein each of the first, second, and third structural members is straight, and is in an aligned, coplanar relationship with another of the first, second, and third structural members.
4. The framework of claim 1 , wherein any number of the structural members and web members protrude in any direction parallel to another of the structural members and web members.
5. The framework of claim 1 , wherein any number of the structural members and web members protrude in any direction perpendicular to another of the structural members and web members.
6. The framework of claim 1 , wherein any number of the structural members and web members protrude in any direction diagonal to another of the structural members and web members.
7. The framework of claim 1 , wherein the framework is included as a portion in at least one member selected from a group consisting of a window frame, a wall stud, a cripple stud, a jack stud, a queen stud, a king stud, a sill plate, a sole plate, a header, a roof truss, a floor joist, a door frame, and a drywall frame.
8. The framework of claim 1 , wherein each web member has a substantially similar thickness to at least one of the structural members connected to the web member.
9. The framework of claim 1 , wherein the framework is configured as at least one of a: plate, a picture window frame window sash housing, a window frame, an operable window, a wall stud, a cripple stud, a jack stud, a queen stud, a king stud, a sill plate, a sole plate, a header, a roof truss, a floor joist, a roof truss, a floor joist, a door frame, a drywall frame, a post, a hollow shell, a truss, a header, a rectangular frame, or a polygonal frame.
10. The framework of claim 1 wherein at least one web member connects the three structural members.
11. The framework of claim 1 wherein adhesive secures the elongated structural members to the web members.
12. A building apparatus comprising:
a framework that includes at least one set of three elongated structural members and at least two web members that maintain the three elongated structural members in a spaced apart, substantially parallel relationship, each of the at least two web members forming a connection between at least two of the three elongated structural members, each set of three elongated structural members and the web members forming a structural-member trio with the second structural member positioned between the first structural member and third structural member,
the structural-member trio having an average cumulative distance between adjacent elongated structural members, and an average normal depth,
wherein, for at least one structural-member trio:
the average cumulative distance between adjacent elongated structural members is less than 80% times the average normal depth, and
the average cumulative distance between adjacent elongated structural members is more than 10% times the average normal depth.
13. The building apparatus of claim 12 , further including insulation.
14. The building apparatus of claim 12 wherein the building apparatus has a thermal resistivity greater than or equal to 0.08° F.·ft 2 per BTUh per inch.
15. The building apparatus of claim 12 wherein there are cavities between the elongated structural members, at least a portion of which are filled with an insulating material.
16. The building apparatus of claim 12 wherein at least one web member connects the three elongated structural members.
17. The building apparatus of claim 12 wherein adhesive secures the elongated structural members to the web members.
18. The building apparatus of claim 12 , wherein the insulating material is rigid.
19. The building apparatus of claim 12 , wherein the insulating material is a foam.
20. The building apparatus of claim 12 , wherein the insulating material is a rigid foam.
