Abstract
A door component, a door, and a method for manufacturing the same. The door may be an external domestic door. The door component includes a thermally insulating material sandwiched by a first layer and a second layer. The component has at least one strengthening bar sandwiched by the first and second layers. The first and second layers are cross-laminated plywood. The strengthening bar(s) are advantageously cross-laminated. Related doors and methods of manufacture are disclosed.

A door component, comprising:
- at least one thermally insulating block sandwiched between a first layer and a second layer;
- wherein the first layer and the second layer comprise cross-laminated plywood;
- a plurality of strengthening bars sandwiched between the first and second layers, including a first strengthening bar and a second strengthening bar;
- wherein the strengthening bars are formed of Laminated Veneer Lumber (LVL);
- wherein the thermally insulating block is:
- bounded on a first side by the first strengthening bar;
- bounded on a second side, opposite the first side, by the second strengthening bar;
- bounded on a third side, disposed between the first and second sides, by the first layer;
- bounded on a fourth side, disposed between the first and second sides and opposite the third side, by the second layer;
- wherein a laminate stacking direction of the first strengthening bar is perpendicular to a laminate stacking direction of the first and second layers.
