Abstract
A vertical thermal C shaped metallic stud having a web with a pair of spaced apart generally parallel legs extending therefrom forming surfaces to receive exterior and interior wall structures. At least one of said legs including an upset struck outwardly from the leg to act as the bearing surface for wall material to be affixed thereto, so that a thermal space is created between the stud and wall material to prevent transfer or lessen the transfer of ambient exterior air temperature by thermal conductivity to the interior of a building using the thermal C shaped studs.
Claims13
An elongated thermal C shaped metallic building stud including a web portion extending between the exterior and interior of a building and a pair of generally parallel legs bent from said web forming an exterior leg and an interior leg and each leg including a strengthening flange struck inwardly toward each other from the ends of said legs opposite said web and generally parallel therewith, said legs each adapted to have secured along their length by fastening means either exterior or interior wall structures, and each leg having exterior and interior generally smooth planar surfaces, said stud further including:
- an upset formed on said smooth surface of the exterior wall of at least one of said legs extending outwardly and said upset is spaced away from the area where said web joins said leg, and there is no upset formed on said web portion, and said upset forming a contact area for said wall structure when said structure is secured to said leg and creating a thermal space between said structure and said generally smooth surface of said leg wherein ambient exterior air temperature, as it may pass by thermal conductivity through said exterior wall structure material, is impeded from conduction through said C shaped metallic building stud and said interior wall material to the interior of said building.
In an elongated thermal C shaped metallic building stud including a web portion extending between the exterior and interior of a building and a pair of generally parallel legs bent from said web forming an exterior leg and an interior leg and each leg including a strengthening flange struck inwardly toward each other from the ends of said legs opposite said web and generally parallel therewith, said legs each adapted to have secured along their length by fastening means either exterior or interior wall structures, and each leg having exterior and interior generally smooth planar surfaces, the improvement comprising:
- a plurality of protuberances in the form of circular bumps are struck from said interior surface of said leg outwardly through said exterior wall and extend beyond said generally smooth planar surface of said leg, said protuberances are all formed away from the area where said web joins said leg and no protuberances are formed in said web portion, the height of said circular bumps define the width of a thermal space between said structure and the planar surface of said leg wherein ambient exterior air temperature as it may pass through said exterior wall structure material is impeded from thermal conduction through said C shaped metallic building stud and said interior wall structure to the interior of said building.
In an elongated thermal C shaped metallic building stud as defined in claim 13 wherein:
- both legs of said stud include a plurality of protuberances formed along the length of said exterior planar surfaces thereof so that there are two thermal spaces created to impede conduction of exterior ambient air temperature into said building.
