A door for a heating stove comprises a main door body 3 comprising hollow reinforcing sections 4, a thin decorated metal plate 1 having left and right edges that are folded back over and attached to left and right edges of the main door body, a convolute spacer 2 of thin metal sheet folded at a series of obtuse angles along vertical and parallel lines to form a zigzag sandwiched between the main door body and the thin decorated metal plate such that the space between the thin decorated plate and the main door body is open to the atmosphere at its top and bottom so that the convolute spacer forms a series of vertical channels. |
