A frameless window construction for walls, doors (1, 31) and other such objects having an extensive surface area is disclosed. The door (1) has an aperture (2) and a thermoformable plastics sheet (5) is used to simultaneously coat the extensive surface and occlude the aperture. Preferably a second sheet (7) is used to coat the other side of the door. If desired a grille (13) can be located in the aperture (2) between the two sheets (5, 7). No frame positioned within the aperture (2) and defining the visible area of the window, is used in the construction. |
