Abstract
A dimensionally adjustable thermally broken door panel having a door thickness, a first and second thermally conductive metal door skins and a plurality of non-thermally conductive trimable edges. Each trimable edge having an edge flange, a door edge and an edge flange thickness. An insert flange can be integrally mounted each of the edge flanges projecting in a direction opposite the door edge, wherein each edge flange can support both the first and second thermally conductive metal door skins in a flush engagement. The dimensionally adjustable thermally broken door panel can prevent thermal transfer between the first and second metal door skins, while enabling dimensional adjustment of the plurality of trimable edges on location to ensure a perfect fit into an existing door frame.
Claims12
A dimensionally adjustable thermally broken door panel having a door thickness, the dimensionally adjustable thermally broken door panel consisting of:
- a. a first thermally conductive metal door skin;
- b. a second thermally conductive metal door skin;
- c. a plurality of non-thermally conductive trimable edges, each non-thermally conductive trimable edge partially contained within the first thermally conductive metal door skin and the second thermally conductive metal door skin, each non-thermally conductive trimable edge comprising:
- i. an edge flange comprising:
- 1. a door edge;
- and
- 2. an edge flange thickness identical to the door thickness;
- and
- ii. an insert flange integrally mounted to the edge flange, the insert flange projecting in a direction opposite the door edge, the insert flange having a thickness at least 5 percent to 60 percent less than the door thickness;
- and wherein the edge flange supports both the first thermally conductive metal door skin and the second thermally conductive metal door skin in a flush engagement;
- and
- d. an internal structural door component comprising a door core and a flange channel for receiving the insert flange from at least one of the plurality of non-thermally conductive trimable edges, the internal structural door component being contained between the first thermally conductive metal door skin and the second thermally conductive metal door skin forming a frame support structure;
- and
- wherein the dimensionally adjustable thermally broken door panel prevents thermal transfer which is a flow of thermal energy between the first thermally conductive metal door skin and the second thermally conductive metal door skin, while simultaneously enabling dimensional adjustment of the plurality of non-thermally conductive trimable edges on location to ensure a perfect fit into an existing door frame.
