A door is provided that includes a door panel having a periphery and opposite first and second panel surfaces, stiles and rails collectively surrounding the panel, and sealant. The stiles have channeled stile surfaces extending across a thickness of the stiles and facing one another. The rails have channeled rail surfaces extending across a thickness of the rails and facing one another. The channeled stile surfaces and the channeled rail surfaces include channels with open ends that receive the periphery of the panel, first grooves positioned at first interfaces of the first panel surface and first edges of the open ends of the channels, and second grooves positioned at second interfaces of the second panel surface and second edges of the open ends of the channels. The sealant is received in the first and second grooves, preferably forming a water-proof seal.

An exemplary door includes a door body and a light assembly. The door body includes a first door panel defining a first panel opening, a second door panel defining a second panel opening, and an internal cavity. The area of the first panel is greater than the area of the second panel opening. The light assembly includes a first trim, a second trim, and an impact-resistant pane positioned in the door cavity. The first trim includes an outer frame coupled to the first door panel and an inner frame positioned in the internal cavity. The pane has an area greater than the area of the second panel opening area, and includes an first outer layer adhered to the inner frame of the first trim, a second outer layer adhered to the door body, and at least one intermediate layer.

A heat-insulating window panel includes: a light-transmissive member having light transmissivity; and a panel member including an outdoor substrate that supports the light-transmissive member from an outdoor side via a first elastic body, an indoor substrate that supports the light-transmissive member from an indoor side via a second elastic body without being in contact with the outdoor substrate, and a heat-insulating material disposed between the outdoor substrate and the indoor substrate, and even when a force is applied to one of the outdoor substrate and the indoor substrate in a direction away from the other to move the one in a separating direction, the outdoor substrate and the indoor substrate have a hooking margin for hooking the one on the other.

Hollow core door apparatus for preventing the build up of pressure in a room having a register through which air flows into the room and the door includes an inside door skin and an outside door skin, and the door skins includes openings through which air flows and a center panel between the skins and spaced part from the skins. The center panel has an outer perimeter greater than the inner perimeter of the openings. The center panel is spaced apart from the skins, and also from the adjacent stiles and rails. A chamber is formed about the panel and between the adjacent stiles and rails and the openings in the skins. Air flow from the room is through the opening in the inside skin into the chamber, around the outer periphery of the panel, and outwardly through the opening in the outside skin in a non-linear manner.

A retention system may comprise a bracket, a bar system, a seal and a bonded washer. The bracket may have a first portion and a second portion. The first portion and the second portion may be operatively coupled together at an angle θ. The bracket may also have a texture. The bracket may define a mounting surface. The bar system may comprise a bar installable in the bracket. The seal may be installable in the bracket and disposed beneath the mounting surface. The bonded washer may be installable on and compressible against the mounting surface.

The problem of using cames for assembling stained glass pieces into a decorative window is solved by mounting the stained glass pieces in retaining channels and by using spacers in the retaining channel for maintaining gaps between adjacent stained glass pieces. The resulting stained glass assembly includes at least two stained glass pieces mounted within a frame and being secured in at least one retaining channel that is mounted to the frame so as to extend at least partially along the inner periphery thereof; and spacers in the retaining channel between each pair of the at least two stained glass pieces that are adjacent so as to create an opened gap therebetween. Such a stained glass assembly can be used as a decorative window in a door or as a dividing wall for example.

An overhead door includes a plurality of articulating panels. At least one of the plurality of articulating panels includes a frame defining an opening, the frame having a ledge and a lip extending from the ledge into the opening and a transparent panel having a first side and an opposing second side. The transparent panel is positioned adjacent to both the lip and the ledge with the first side of the transparent panel positionable adjacent the lip. The plurality of articulating panels further includes a retainer member positionable adjacent the second side of the transparent panel and operable to be fastened to the frame.

A molded door skin with integral divided light bars. The divided light bars are either true divided light (TDL) bars simulated divided light (SDL) bars or decorative grilles. The door skin includes a body portion and a divided light bar portion. The body portion and divided light bar portion are of one-piece construction which is preferably compression molded from fiberglass or other synthetic materials. Once assembled into a door with door glass installed, the divided light bars form a number of small windows for either simulating the appearance of traditional divided light windows in SDL applications, holding individual panes of insulating glass units in TDL applications, or for decorative purpose only.

A thermally-broken ornamental door includes a thermally-broken door and a thermally-broken jamb through which thermal transfer is greatly minimized. The thermally-broken door includes an outer panel and an inner panel that are minimally connected through a plurality of door bridging strips. The thermally-broken jamb includes an outer jamb frame and an inner jamb frame that are minimally connected through a plurality of jamb bridging strips. An insulating foam panel is present between the outer panel and the inner panel while an insulating foam core is present between the outer jamb frame and the inner jamb frame. A window assembly is hingedly mounted into the thermally-broken door and includes a retaining spacer frame that minimizes thermal transfer from an exterior environment to an inner window frame through a glass panel of the window assembly. The retaining spacer frame additionally provides structural support to the glass panel.

Hollow core door apparatus for preventing the build up of pressure in a room having a register through which air flows into the room and the door includes an inside door skin and an outer door skin, and the door skins includes openings through which air flows and panels disposed in the openings to define the amount of air flowing through the openings in the skins. The door also includes at least a single fixed panel and a movable panel, both of which panels include openings through which air flows when the openings in the panels are aligned and which air flow is restricted when the openings are misaligned. The inside and outside panels have peripheral openings defined between the openings in the skins and the panels disposed in the openings and which peripheral openings define areas at least as great as the area of the openings in the fixed and movable panels, and the openings in the fixed and movable panels are offset from the peripheral openings to provide for a non-linear flow of air through the door to prevent the build up of pressure in the room and to restrict the non-linear air flow through the door when the openings in the fixed and movable panels are misaligned. An embodiment combining a noxious gas absorbent material with the pressure build up prevention capability is also illustrated.
