Abstract

A door assembly of the type having a frame mounted to a wall. The frame comprises a head portion, opposed vertical jamb portions and a sill portion. Doors are provided in the frame. A door in the frame is displaceable between an open position and a closed position. The doors comprise a sash portion supporting a see-through panel. Each of the head portion, the jamb portion, the sill portion, and the sash portion of the door has one external cladding and one internal cladding. The external cladding and the internal cladding are detachably connected to one another, such that only the external cladding is exposed to an exterior of the door assembly and only the internal cladding is exposed to an interior of the door assembly when the door is in the closed position. A method for interconnecting two hollow elongated extruded sections of the door sash is also provided.

Claims

1. A door assembly of the type having a frame mounted to a wall, the frame having a head portion, opposed vertical jamb portions and a sill portion, at least one door in the frame displaceable between an open position and a closed position, the door having a sash portion supporting a see-through panel, the door assembly comprising:

one external cladding and one internal cladding being detachably connected to one another, for each of;

the head portion of the frame;

the jamb portion of the frame;

the sill portion of the frame; and

the sash portion of the door;

such that only the external cladding is exposed to an exterior of the door assembly and only the internal cladding is exposed to an interior of the door assembly when the door is in the closed position.

2. The door assembly according to claim 1, wherein at least one of the external cladding and the internal cladding of at least one of the jamb portions and the sash portion are formed of elongated members having a common cross section.

3. The door assembly according to claim 2, wherein the external cladding consists of extruded sections.

4. The door assembly according to claim 2, wherein the internal cladding is formed of at least one of extruded polyvinyl chloride, extruded polyurethane, wood components and insulated aluminum.

5. The door assembly according to claim 2, wherein the elongated extruded members having a common cross section are extruded with a same die.

6. The door assembly according to claim 1, comprising two doors, a first one of the doors being fixed to the frame and a second one of the doors being displaceable in translation in the frame between an open position and a closed position.

7. The door assembly according to claim 1, wherein the external cladding and the internal cladding are interconnected without the use of fasteners visible from at least one of the exterior and the interior of the door assembly.

8. The door assembly according to claim 3, wherein the extruded sections of the sash portion have beveled ends for perpendicular connection between the extruded sections.

9. The door assembly according to claim 8, wherein the aluminum extruded sections are interconnected by a connector received in cavities of the extruded sections and crimped thereto.

10. The door assembly according to claim 9, wherein gaps are provided in the connector adjacent contact surfaces between an outer periphery of the connector and a wall of the cavities of the extruded sections, for receiving a crimped portion of the extruded sections.

11. The door assembly according to claim 10, wherein crimping portions of the extruded sections are positioned on an outer periphery of sash portion not to be visible.

12. The door assembly according to claim 1, wherein the internal cladding and the external cladding define closed cavities, the internal cladding and the external cladding being provided with unidirectional flow valves between closed cavities such that fluid having infiltrated the closed cavities is drained to an exterior of the door assembly.

13. The door assembly according to claim 1, further comprising an intermediate core between the internal cladding and the external cladding, the intermediate core connecting the internal cladding to the external cladding without fasteners visible from at least one of the exterior and the interior of the door assembly.

14. The door assembly according to claim 13, wherein the external cladding consists of extruded aluminum sections, the intermediate core is selected from a group consisting of at least one of extruded polyvinyl chloride, extruded polyurethane, and insulated aluminum, and the internal cladding is selected from a group consisting of at least one of extruded aluminum sections, wood components and extruded polyvinyl chloride.

15. The door assembly according to claim 13, wherein the intermediate core has a lower thermal conductivity than the external cladding.

16. The door assembly according to claim 3, wherein the extruded sections of the external cladding consists of extruded aluminum sections.

17. The door assembly according to claim 1, wherein the external cladding has first connection fingers extending toward an interior, and the internal cladding has second connection fingers extending toward an exterior, for cooperating engagement between the first connection fingers and second connection fingers when the first cladding and the second cladding are detachably connected.

18. A door assembly of the type having a frame mounted to a wall, the frame comprising a head portion, opposed vertical jamb portions and a sill portion, at least one door in the frame displaceable between an open position and a closed position, the door comprising a sash portion supporting a see-through panel, wherein each of the head portion, the jamb portion, and the sill portion of the frame, and the sash portion of the door has one external cladding and one internal cladding, the external cladding and the internal cladding being detachably connected to one another, such that only the external cladding is exposed to an exterior of the door assembly and only the internal cladding is exposed to an interior of the door assembly when the door is in the closed position, wherein the internal cladding and the external cladding define closed cavities, the internal cladding and the external cladding being provided with unidirectional flow valves between closed cavities such that fluid having infiltrated the closed cavities is drained to an exterior of the door assembly.
