Abstract
A method comprises a) attaching a first skin to a first surface of an open cell foam to form a precursor for a door, window or panel; and b) attaching a second skin to the precursor in a separate step from step a). A precursor for a door, window, or panel, comprises a skin attached to one face of an open cell foam, but not to an opposing face of the open cell foam.

A method comprising:
- a) attaching a first skin to a first surface of an open cell foam to form a precursor for a door, window or panel;
- and
- b) attaching a second skin to the precursor in a separate step from step a),
- wherein prior to attaching the second skin to the precursor, the precursor is modified,
- wherein the second skin is attached to the precursor at a different location from the location at which the first skin is attached to the precursor,
- wherein, prior to attaching the second skin to the precursor, the precursor is shaped, trimmed, routed, drilled, varnished, coloured, or waxed.

A method of forming a door, window or panel, which method comprises:
- a1) attaching a first skin to a first surface of an open cell foam to form a first precursor for a door, window or panel, which precursor has an exposed foam surface;
- a2) attaching a second skin to a first surface of an open cell foam to form a second precursor for a door, window or panel, which precursor has an exposed foam surface;
- and
