Building Panel

Abstract

A building panel has an outer skin spaced from an inner skin, sandwiching an insulation material. A first end of the outer skin includes a step portion, an indented fastener receiving portion and a first flange. The first flange extends outwardly toward a surface of the outer skin. A seal is mounted on the first flange. The inner skin includes a first end. The inner skin first end includes a shelf and a second flange extending from the shelf. A second seal is positioned on the second flange. A second end of the outer skin includes a portion to receive an outer skin first end of an adjoining panel. A second end of the inner skin includes a portion to receive an inner skin first end of the adjoining panel.

What is claimed is: 
     
         1 . A building panel comprising:
 an exterior skin;   an interior skin;   foam sandwiched between the exterior and interior skins forming the building panel;   the building panel has two ends, the first end is defined by the exterior skin having a first and second step portion adjacent one another, both step portions including a tread and riser, the second riser is positioned closer to the interior skin, a third step portion in a direction opposite to the first and second step portions, a third tread extends away from the second riser forming a receiving channel between the second and third treads, a third riser extends from the third tread, the third riser is substantially perpendicular to the second riser and includes a seal, the interior skin includes a fourth step portion with a fourth tread extending toward the exterior skin and a fourth riser, a seal is positioned on the fourth riser, the second end includes a pair of channels for receiving seals on adjacent panels, the interior skin seal is positioned closer to the first end.   
     
     
         2 . The building panel of  claim 1 , wherein the exterior skin first and second treads are sloped. 
     
     
         3 . The building panel of  claim 1 , wherein a gap is formed between the first flange and the foam. 
     
     
         4 . The building panel of  claim 1 , wherein the interior skin fourth riser has a U-shape with a gap between legs of the U to receive foam. 
     
     
         5 . The building panel of  claim 4 , wherein the foam between the exterior skin third riser and interior skin fourth riser has a tapered surface. 
     
     
         6 . A joint clip for securing a building panel to a frame structure comprising:
 a base having at least one aperture, a pair of walls extending from sides of the base, the walls and base defining a cavity, a resilient pad positioned in the cavity for sealing a fastener passing through the base aperture, and a fastener passing through the base aperture and pad for securing the clip to a frame structure and, in turn, securing a building panel on the frame structure.   
     
     
         7 . The joint clip of  claim 6 , wherein the fastener has a pair of spaced apart threads. 
     
     
         8 . The joint clip of  claim 6 , wherein the fastener has a self-tapping pilot tip.
