The frame defines the window characteristically on the outside, while the window ledge had the double role of ledge and cover and protects the window from atmospheric agents. The threshold, on the contrary, is placed under the door. We produce thresh holds of varying dimensions. Larger ones which complete and complement a slate doorway and other less imposing ones which define the division between rooms.
