Abstract

Abstract A thermal and moisture resistant door comprises a perimeter framework with a laminated skin glued to the interior and exterior sides of the framework, with an insulative core material therebetween. Laminated panels are secured to the skin on one or both sides of the door to provide the desired decorative appearance. Each skin and panel includes at least one cross-banding layer, a vapor barrier layer, and an outer veneer layer. Each panel is routed or molded such that an intermediate wood layer is visible, while the remaining layers of the panel are substantially concealed.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 415 words
A thermal and moisture resistant door, comprising: a framework defining the perimeter edges of said door and defining the interior and exterior sides of said door, said framework including opposite elongated side frame members, a top frame member extending between said side frame members at the upper ends thereof, and a bottom frame member extending between said side frame members at the lower ends thereof; a laminated skin secured to said framework on the interior and exterior sides of said door, said skin including an inner wood backer layer attached to said framework and having the wood grain running substantially parallel to the length of the door, a first wood cross-banding layer attached to said backer layer and having the wood grain running substantially perpendicular to the length of the door, a vapor barrier layer attached to said first cross-banding layer, a second wood cross-banding layer attached to said vapor barrier layer and having the wood grain running substantially perpendicular to the length of the door, and an outer wood veneer layer attached to said second cross-band layer and having the wood grain running substantially perpendicular to the length of the door; a laminated panel secured to said skin on at least one side of said door, said panel including an inner first wood cross-banding layer attached to said veneer layer of said skin, an intermediate wood layer attached to said first cross-banding layer, a second wood cross-banding layer attached to said intermediate wood layer, a vapor barrier layer attached to said second cross-banding layer, a third wood cross-banding layer attached to said vapor barrier layer and an outer wood veneer layer attached to said third cross-banding layer, the wood grain of said intermediate layer and the wood grain of said veneer layer running substantially parallel to one another and the wood grain of at least one of said cross-banding layers running substantially perpendicular to the wood grain of said veneer layer; wherein the layers of lamination of said skins provide strength to the door to prevent warping of the door due to temperature differentials across the door; wherein the layers of lamination of said panel provide strength to the door and panel to prevent warping of the door and panel due to temperature differentials across the door and panel; wherein said vapor barriers in said skins prevent warping of the door due to moisture absorption thereby; and wherein said vapor barrier in said panel prevents warping of the panel due to moisture absorption thereby.
Claim 2
Dependent Claim 415 words
A thermal and moisture resistant door, comprising: a framework defining the perimeter edges of said door and defining the interior and exterior sides of said door, said framework including opposite elongated side frame members, a top frame member extending between said side frame members at the upper ends thereof, and a bottom frame member extending between said side frame members at the lower ends thereof; a laminated skin secured to said framework on the interior and exterior sides of said door, said skin including an inner wood backer layer attached to said framework and having the wood grain running substantially parallel to the length of the door, a first wood cross-banding layer attached to said backer layer and having the wood grain running substantially perpendicular to the length of the door, a vapor barrier layer attached to said first cross-banding layer, a second wood cross-banding layer attached to said vapor barrier layer and having the wood grain running substantially perpendicular to the length of the door, and an outer wood veneer layer attached to said second cross-band layer and having the wood grain running substantially perpendicular to the length of the door; a laminated panel secured to said skin on at least one side of said door, said panel including an inner first wood cross-banding layer attached to said veneer layer of said skin, an intermediate wood layer attached to said first cross-banding layer, a second wood cross-banding layer attached to said intermediate wood layer, a vapor barrier layer attached to said second cross-banding layer, a third wood cross-banding layer attached to said vapor barrier layer and an outer wood veneer layer attached to said third cross-banding layer, the wood grain of said intermediate layer and the wood grain of said veneer layer running substantially parallel to one another and the wood grain of at least one of said cross-banding layers running substantially perpendicular to the wood grain of said veneer layer; wherein the layers of lamination of said skins provide strength to the door to prevent warping of the door due to temperature differentials across the door; wherein the layers of lamination of said panel provide strength to the door and panel to prevent warping of the door and panel due to temperature differentials across the door and panel; wherein said vapor barriers in said skins prevent warping of the door due to moisture absorption thereby; and wherein said vapor barrier in said panel prevents warping of the panel due to moisture absorption thereby.
Claim 3
Dependent Claim 157 words
The door of claim 1 wherein said intermediate layer of said panel is substantially thicker than the other layers of said panel and said panel is routered along at least one edge so as to provide an edge to said first cross-banding layer which is substantially perpendicular to the surface of the veneer layer of said skin and to provide an enlarged surface of said intermediate layer and to provide coplanar edges to said second and third cross banding layer, said vapor barrier layer and said veneer layer which are substantially perpendicular to the surface of said veneer layer of said skin, whereby said enlarged surface of said intermediate layer is visible adjacent said routered edge and said edges of said cross banding layers, said vapor barrier layer and said veneer layer of said panel are substantially concealed from view with a line of sight substantially perpendicular to the surface of the veneer layer of the skin.
Claim 4
Dependent Claim 16 words
The door of claim 1 further comprising insulative material between said skins and within said framework.
Claim 5
Dependent Claim 23 words
The door of claim 1 wherein said backer layer of said skins and said cross-banding layers of said skins are straight grained wood.
Claim 6
Dependent Claim 15 words
The door of claim 1 wherein said vapor barrier layers of said skins are aluminum.
Claim 7
Dependent Claim 14 words
The door of claim 1 wherein said veneer layer of said skins is hardwood.
Claim 8
Dependent Claim 56 words
The door of claim 1 wherein said backer layer of said skins and said cross-banding layers of said skins range in thickness from 0.015 inch to 0.060 inch, said vapor barrier layer ranges in thickness from 0.002 inch to 0.020 inch, and veneer layer of said skins ranges in thickness from 0.015 inch to 0.060 inch.
Claim 9
Dependent Claim 16 words
The door of claim 1 wherein said cross-banding layers of said panel are straight grained wood.
Claim 10
Dependent Claim 15 words
The door of claim 1 wherein said vapor barrier layer of said panel is aluminum.
Claim 11
Dependent Claim 15 words
The door of claim 1 wherein said veneer layer of said panel is hard wood.
Claim 12
Dependent Claim 69 words
The door of claim 1 wherein said cross-banding layers of said panel range in thickness from 0.015 inch to 0.060 inch, said intermediate wood layer of said panel ranges in thickness from 0.125 inch to 0.475 inch, said vapor barrier layer of said panel ranges in thickness from 0.002 inch to 0.020 inch and said veneer layer of said panel ranges in thickness from 0.015 inch to 0.060 inch.
