A threshold with regard to construction refers to the strip of wood, stone or metal that sits at the bottom of a doorway making the cross over from one to another smooth and hazard free. A threshold can vary in size depending on the doorway, the room and the style of the building. Some thresholds are very wide, particularly if they are in older homes and it is the entrance between a formal dining room and a hallway. The threshold of a standard door is usually a size that appropriately fits the door size. Some prefabricated doors come with the threshold as a part of the package to ensure it is the correct size for the door.
When you are remodeling an area of your home and putting in new flooring, you might want to think carefully about the thresholds in the house. When flooring is replaced it often changes the level of the floor and this can alter the effectiveness of the thresholds of the doorways as well as create trip hazards. A professional in woodwork or flooring can recreate the thresholds in your home so that they fit the new flooring and make for a smoother pass from one room to the next. The threshold between the rooms should help you to get from one room to the other safely but it should also create a beautiful way to decorate your home. The different materials used for the threshold can provide a different look for the rooms it crosses.
