Perimeter structures for joining abutting enclosure components

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;
• a C-shaped abutting end cap secured to the planar laminate and configured to be secured to an abutting planar enclosure component, the abutting end cap comprising:
• an elongate web surface abutting the generally linear edge of the planar laminate;
• a first inclined fastener shelf extending from a first edge of the elongate web surface oriented to direct a leading portion of a screw or nail fastener through the web surface and away from the planar laminate into the abutting planar enclosure component;
• a second inclined fastener shelf extending from a second edge of the elongate web surface and oriented to direct a leading portion of a screw or nail fastener through the web surface and away from the planar laminate into the abutting planar enclosure component;
• and
• a first elongate flange surface and a second elongate flange surface, the first elongate flange surface and the second elongate flange surface being spaced-apart by a distance, regions of the first and second elongate flanges are canted inward towards each other proximate the first and second inclined fastener shelve such that the first elongate flange surface is canted inward to join the first inclined fastener shelf at a first point to provide access to the first inclined fastener shelf for receipt of the screw or nail fastener by the first inclined fastener shelf and the second elongate flange surface is canted inward to join the second inclined fastener shelf at a second point to provide access to the first inclined fastener shelf for receipt of the screw or nail fastener by the first inclined fastener.

A reinforced enclosure member for a building structure, comprising:

• (a) 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;
• (b) a reinforced end cap comprising:
• (1) a first elongate flange surface joined to an elongate web surface at a first junction, a second elongate flange surface joined to the elongate web surface at a second junction, 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;
• (2) 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 between the elongate cavity wall and the elongate web surface;
• and
• (3) a filler reinforcement within the reinforcement channel;
• and
• (c) the reinforced 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.
