Abstract
The invention relates to the manufacturing of solid wood doors and consists in increasing the insulating value of a door by inserting an insulating material between the internal and external panels and in the center of the structural parts of the door. In this way, a door with a minimum of non-insulated surfaces is achieved. By using this system, the insulating value of the assembled door is significantly increased and reach the requirements of high energy efficiency programs such as ENERGY STAR™. In addition to this, the rigidity and the durability of the solid wood door are not significantly compromised. A door with a traditional style and high thermal resistance levels is achieved.
Claims18
A door comprising:
- a first and second vertical stile defining vertical edges of the door with the first stile comprising attaching elements for hingedly connecting the door to a door frame;
- a top and bottom horizontal rail connecting the two vertical stiles and defining a top and bottom edge of the door;
- the stiles and rails delimiting at least one panel of the door having an external and an interior surface;
- and
- at least one insulator member embedded between at least two separate parts affixed together to form each of the stiles and the at least one panel.
A method for making a door, the door comprising at least two vertical stiles defining vertical edges of the door with a first stile comprising attaching elements for hingedly connecting the door to a door frame and a second stile, opposite to the first stile;
- a top and bottom horizontal rail connecting the two vertical stiles and defining a top and a bottom edge of the door;
- the stiles and the rails delimiting at least one panel of the door having an external and an interior surface;
- the method comprising the steps of:
- a) embedding at least one first insulator member between at least two separate parts affixed together to form each of the stiles;
- b) embedding at least one second insulator member between at least two separate parts affixed together to form the at least one panel;
- and
- c) assembling the stiles, the rails and the at least one panel to form the door.
