Abstract: A metal roof truss assembly is provided comprising a plurality of elongated structural members, including a top chord, a bottom chord, and a web member. Each structural member comprises a planar base and planar legs extending from the longitudinal edges of the base. The base and the legs define an open longitudinal channel. A flange integral with the longitudinal edges of each leg has a planar first portion extending outwardly from the legs and a planar second portion extending from the longitudinal edges of the first portion of the flanges. The end of a first structural member is inserted into the channel defined by the legs and the base of a second structural member. The inserted end of the first structural member has no flanges for a length equal to at least the depth to which the first structural member is received in the channel of the second structural member so that the outer surface of the legs of the first structural member are adjacent the inner surface of the legs of the second structural member.

Abstract: A metal truss comprises elongated top chord members connected to each other at their ends. A first elongated bottom chord member is connected at its ends to the top chord members adjacent the free ends of the top chord members. A second elongated bottom chord member is connected at its ends to the top chord members, or directly to the first bottom chord member via spacers, such that the second bottom chord member is spaced below the first bottom chord member. At least one web member is positioned between and interconnecting at least one top chord member and the first bottom chord member. One end of the web member is connected to the at least one top chord member and the other end of the web member is connected to the first bottom chord member.

Abstract: A thermal wall system for slowing heat transfer through walls. The system includes horizontal top and bottom tracks, horizontal top and bottom plates, and vertical studs mounted to and extending between the top and bottom plates. The top tracks and plates have flanges that extend downward. The bottom tracks and plates have flanges that extend upward. The width of the plates fits within the width of the tracks. Top and bottom tracks and plates are respectively nested along their webs and one flange to form a longitudinal opening between their respective opposing flanges. Rigid insulation may be disposed in the longitudinal opening. Thermal framing components may also be provided, extending between the top and bottom plates, to support vertical edges of insulation sheets. Thermal end caps may be used to treat the terminal edges of insulation.

Abstract: 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.
