Enclosure component perimeter structures

1. An enclosure member for a building structure, comprising:

a planar laminate having a generally linear edge comprising a first facing layer; a layer of foam having a first face and a second opposing face; and a second facing layer; the first facing layer fastened to the first face of the layer of foam, and the second facing layer fastened to the second opposing face of the layer of foam;

an abutting end cap comprising:

a first elongate flange surface, an elongate web surface and a second elongate flange surface, the first elongate flange surface and the second elongate flange surface being spaced-apart by a distance; the web surface, the first elongate flange surface and the second elongate flange surface generally forming a C-channel shape;

a first inclined fastener shelf joined at a first point to the first elongate flange surface and to a first edge of the elongate web surface, an inclined surface of the first inclined fastener shelf joins, at the first point, a portion of the first elongate flange surface that is canted inwardly to form a V-shaped recess, and a second inclined fastener shelf joined at a second point to the second elongate flange surface and to a second edge of the elongate web surface, each of the first and second inclined fasteners shelves oriented to direct a leading portion of a screw or nail fastener through the web surface and away from the planar laminate into an abutting planar enclosure component;

the abutting end cap secured to the generally linear edge of the planar laminate, with the distance spacing apart the first and second elongate flange surfaces adapted to receive between them at least the generally linear edge of the layer of foam.

2. The enclosure member as in claim 1 , wherein the first elongate flange surface is canted inwardly proximate to the first point, and the second elongate flange surface is canted inwardly proximate the second point.

3. The enclosure member of claim 2 , wherein the first and second elongate flanges are canted inward at an angle of approximately thirty degrees proximate to the first point.

4. The enclosure member of claim 2 , wherein the first inclined fastener shelf has an incline of approximately sixty degrees relative to a portion of the first elongate flange surface that is perpendicular to the elongate web surface.

5. The enclosure member as in claim 1 , further comprising an elongate cavity wall joined to each of the first and second elongate flange surfaces, the elongate cavity wall being spaced from and generally parallel to the elongate web surface, and spanning the distance spacing apart the first and second elongate flange surfaces, to define a reinforcement channel.

6. The enclosure member as in claim 1 , wherein the first facing layer and the second facing layer are each selected from the group consisting of (a) a structural layer comprising a plurality of structural panels of inorganic oxide, (b) a layer of metallic sheet, and (c) a combination of a protective layer comprising a plurality of structural panels of inorganic oxide and a layer of metallic sheet.

7. The enclosure member of claim 1 , wherein the abutting end cap further comprises:

a receiving slot formed in and opening outwardly from an exterior surface of the elongate web surface away from the C-channel shape, the receiving slot adapted to receive sealing heads.

8. The enclosure member of claim 1 , wherein the first inclined fastener shelf is accessible from a side of the C-channel shape formed by the first elongate flange surface.

9. The enclosure member of claim 1 , wherein the first inclined fastener shelf is adapted to receive fasteners at a non-zero angle relative to the elongate web surface.

10. The enclosure member of claim 1 , wherein a face of the first inclined fastener shelf is oriented outwardly from a first side of the C-channel shape that includes the first elongate flange surface.
