Wall stud with a thermal break

摘要

Insulating material is sandwiched between one edge of a structural 2×4 and one edge of a structural 2×2 to form a 2×6 wall stud with a thermal break. While shapes, sizes and compositions of the structural members can vary, the insulated wall stud has the advantage of being the size of conventional lumber reducing installation cost.

主权项

1. An insulated wall stud, comprising:
at least a first elongated structural member, the at least first elongated structural member having a first depth of dimensional lumber; at least a second elongated structural member, the at least second elongated structural member having a second depth of dimensional lumber; each elongated structural member has a width, the width of the at least first elongated structural member is equal to the width of the at least second elongated structural member; insulating material sandwiched between the widths of the elongated structural members, the insulating material having a thickness less than the first depth of the first elongated structural member and less than the second depth of the second elongated structural member, wherein the at least first elongated structural member, the at least second elongated structural member and the insulating material are connected to prevent thermal bridging; wherein each elongated structural member is at least a 2×2 piece of dimensional lumber, the first depth of the at least first elongated structural member, the second depth of the at least second elongated structural member and the thickness of the insulating material combine to form the insulated wall stud that has a combined depth of dimensional lumber; and wherein said insulating material comprises at least one of (a) a fire resistant material and (b) voids and is non-continuous.
