Thermal framing component
A thermal framing component for use in wall framing. The thermal framing component includes an elongated web with tabs in alternating positions and with at least some bent at right angles to the web. The bent tabs form slots on both sides of the web into which rigid insulation is reciprocally received. The tabs also provide mounting surfaces for exterior sheathing or finish materials. The component may be used in metal framing, wood framing, or a combination thereof. The component may improve thermal performance of a wall by limiting the heat transfer through the wall, for example, by avoiding direct paths for conduction of heat through the wall. Methods of making and installing the component and assemblies are provided.
1. A thermal framing assembly for use in wall framing, comprising:
a top plate;
a bottom plate substantially parallel to and spaced from the top plate;
two spaced vertical studs, each including a stud upper end and a stud lower end, the stud upper end mounted to the top plate and stud lower end mounted to the bottom plate;
a thermal framing component interposed between the vertical studs and including a component upper end and a component lower end, the component upper end mounted to the top plate and component lower end mounted to the bottom plate, including:
an elongated planar web including a longitudinal axis, a first edge parallel to the longitudinal axis, a second edge parallel to the longitudinal axis, a first side, and a second side;
a first planar tab extending from the first edge at approximately a 90 degree angle from the first side;
a second planar tab extending from the first edge at approximately a 90 degree angle from the second side in a direction opposite that of the first tab;
a third planar tab extending from the second edge at approximately a 90 degree angle from the second side in the direction opposite that of the first tab; and
a fourth planar tab extending from the second edge at approximately a 90 degree angle from the first side in the direction opposite the third tab,
wherein the third tab is in longitudinal registration with the first tab, wherein the fourth tab is in longitudinal registration with the second tab, and wherein the second tab is longitudinally adjacent to the first tab, and
rigid insulation having an edge in close and complementary registration with a side of the web,
wherein the first and second tabs are entirely within the same plane and the third and fourth tabs are entirely within the same plane.
2. The thermal framing assembly of claim 1 , further comprising mid-span blocking, wherein the thermal framing component is mounted to the mid-span blocking.
3. An assembly for use in wall framing, comprising:
a top plate;
a bottom plate substantially parallel to and spaced from the top plate;
two spaced vertical studs, each including a stud upper end and a stud lower end, the stud upper end mounted to the top plate and stud lower end mounted to the bottom plate; and
a strip interposed between the vertical studs and including a strip upper end and a component lower end, the strip upper end mounted to the top plate and strip lower end mounted to the bottom plate, including:
an elongated planar web including a longitudinal axis, a first edge parallel to the longitudinal axis, a second edge parallel to the longitudinal axis, a first side, and a second side;
a first planar tab extending from the first edge at approximately a 90 degree angle from the first side;
a second planar tab extending from the first edge at approximately a 90 degree angle from the second side in a direction opposite that of the first tab;
a third planar tab extending from the second edge at approximately a 90 degree angle from the second side in the direction opposite that of the first tab; and
a fourth planar tab extending from the second edge at approximately a 90 degree angle from the first side in the direction opposite the third tab,
wherein the third tab is in longitudinal registration with the first tab, wherein the fourth tab is in longitudinal registration with the second tab, and wherein the second tab is longitudinally adjacent to the first tab.
4. The assembly of claim 3 , further comprising rigid insulation having an edge in close and complementary registration with a side of the web.
5. The assembly of claim 3 , further comprising mid-span blocking, wherein the component is mounted to the mid-span blocking.
6. The assembly of claim 3 , wherein the first and second tabs are entirely within the same plane and the third and fourth tabs are entirely within the same plane.
7. The assembly of claim 3 , wherein the first and second tabs are free of apertures.
