A sectional door panel comprising:
- a front panel;
- a rear panel located behind said front panel;
- an upper edge extending from said front panel;
- a raised tongue formed across the length of said upper edge;
- a lower edge extending from said front panel;
- a concave groove formed across the length of said lower edge, wherein said raised tongue of a first sectional door panel is engagable with said concave groove of a second sectional door panel;
- and
- a means for locating said rear panel such that the plane defined by said rear panel intersects said raised tongue and said concave groove.
A sectional door panel comprising:
- a front panel;
- a rear panel located behind said front panel;
- an insulating material located between said front panel and said rear panel;
- an upper edge integral to said front panel, extending behind said rear panel;
