Benefits of technology

[0009]More specifically, there is provided a framing component with built-in-thermal break for a wall of a building, comprising: a structural member; and an insulation member secured to the structural member on an inside of the building; wherein the structural member is made in wood, the insulation member is made in a thermal break material; the structural member and the insulation member forming a one-piece insulated framing component, a bearing depth of the component being smaller than a bearing depth of the wall.

Problems solved by technology

Since heat flows through the path of least resistance, thermal bridges can contribute to poor energy performance.
This system requires that the builder makes multiple trips around the building, which greatly increases labor costs.
Moreover, it also increases the wall thickness, resulting in more expensive window and door jambs extension for example.

Embodiment Construction

[0020]There is provided a complete framing system including studs, plates, and headers, all designed to work together with a continuous structural load path, an insulation plane, and a nailer plane (see FIG. 2a).

[0021]As illustrated in FIGS. 2b, 2c and 2d, a stud 20, a header 40 and a plate 60 generally each comprises an insulation member 24 sandwiched between a structural member 22 and a support 26.

[0022]The structural member 22 is typically a wood member, which provides the strength needed to support load. It can be made in a range of lumber species or engineering lumbers, such as, for example, solid sawn lumber, spruce-pine-fir (spf), Douglas fir (df), Hem-fir (Hf), or finger jointed or engineered LVL (laminated veneer lumber), plywood, oriented strand board (OSB).

[0023]The insulation member 24 is a thermal break material, generally a poor conductor of heat. Typically, the insulation member 24 is a rigid foam material, providing thermal insulation. Spray urethane may be used as b...

Abstract

Framing component with built-in-thermal break, comprising a structural member and an insulation member secured to the structural member on an inside of a building, the structural member being made in wood, the insulation member being made in a thermal break material; the structural member and the insulation member forming a one-piece insulated framing component, a bearing depth of the component being smaller than a bearing depth of the wall.

Description

FIELD OF THE INVENTION[0001]The present invention relates to framing systems. More specifically, the present invention is concerned with a framing system and components with built-in thermal break.BACKGROUND OF THE INVENTION[0002]Standard construction today in residential and light commercial wood framing uses either 2×4 or 2×6 solid lumbers spaced 16″ on center. Energy conservation concerns and building codes have forced most builders to frame exterior wall with 2×6's. Framing requirements (roof loads, carry beams, headers) and details (window and door openings, inside and outside corners, wall intersections) greatly increase the amount of solid wood in an exterior wall. The United States national average is 25 percent of the wall as a solid wood framing.[0003]Thermal bridges are points in the building envelope that allow heat conduction to occur. Since heat flows through the path of least resistance, thermal bridges can contribute to poor energy performance. A thermal bridge is cr...
