Through-wall metal flashing having thermal breaks

摘要

A through-wall flashing device includes a metal exterior surrounding a polymeric core, wherein the metal exterior is substantially non-continuous or otherwise interrupted by thermal breaks disposed about the metal exterior. In assembly, the thermal breaks help to reduce or all together eliminate thermal bridging from an exterior of a building construction to the interior of a building or building wall. The through-wall flashing device is adapted for use with a variety of wall constructions and is specifically configured to provide insulation and moisture sheeting properties around doors, windows and other architectural apertures which may be found in a wall construction.

主权项

1. A through-wall flashing system comprising:
a polymeric core having a first end and a second end spaced apart from the first end: a body portion extending between the first end and the second end, the body portion including an upper surface and a lower surface opposite the upper surface, an outer edge and an inner edge; an interior panel extending between the first end and the second end, and upwardly from the upper surface of the body portion proximate the inner edge, the interior panel having an inner surface and an outer surface; an exterior panel extending between the first end and the second end, and downwardly from the lower surface of the body portion proximate the outer edge, the exterior panel having an inner surface and an outer surface; wherein the body portion is positioned and oriented one of oblique and perpendicular to each of the interior panel and the exterior panel; an exterior facing attached to the polymeric core, the exterior facing comprising a sheet metal member having: a first skin extending between the first end and the second end, and from the outer surface of the exterior panel over the outer edge and over a portion of the upper surface of the body portion; a second skin extending between the first end and the second end, and from the upper surface of the body portion over the inner edge and over a portion of the outer surface of the interior panel; a third skin extending between the inner surface of the exterior panel over the outer edge and over a portion of the lower surface of the body portion; a fourth skin extending between the lower surface of the body portion, over the inner edge and over a portion of the inner surface of the interior panel; wherein the first skin and the second skin are spaced apart from each other on the upper surface of the body portion so as to define at least one upper thermal break therebetween extending from the first end to the second end of the polymeric core, thereby exposing the upper surface thereof, and wherein the third skin and the fourth skin are spaced apart from each other on the lower surface of the body portion so as to define at least one lower thermal break therebetween extending from the first end to the second end of the polymeric core, thereby exposing the lower surface thereof.
