Types of Door Hinges
Many people might be surprised to learn how many different types of door hinges there are. A door hinge is a door hinge, you may think and not a particularly exciting piece of ironmongery! But there are actually a wide variety of door hinge types available and it is important that you select the correct one to suit your requirements. Here we will go through each one and explain exactly what it does and what kind of application it is best suited to.
Antique Door Hinges and Hinge Fronts
Antique Door Hinges and Hinge Fronts are used in traditional properties such as cottages, listed buildings, manor houses and country homes. They are usually fitted to ledged and braced doors and used in conjunction with a thumb latch. Antique door hinges are used to actually hold the door, while hinge fronts can be fitted on top of standard hinges to create an authentic antique look in your home.
Ball Bearing Hinges
Ball Bearing Hinges are the most popular type of hinge and are used on internal doors. The hinge pivots on a series of small ball race bearings, offering a much smoother action. These hinges are generally made of steel or stainless steel and come in a whole host of finishes and the most common sizes are 3” and 4”.
Butt Door Hinges
Butt Door Hinges are suitable for a range of applications in both domestic and commercial situations. They vary in size from 25mm up to 200mm inches. A butt door hinge is measured by its height, which usually refers to the length of the knuckle. 64mm butt door hinges are used on cabinet doors and thin standard doors. 75mm hinges are used on 35mm thick standard internal doors. 100mm hinges are usually found on external doors and internal fire doors that are 45mm thick. Please note that fire doors by regulation have to have three hinges per door.
Parliament and Projection Hinges
Parliament and Projection Hinges are hinges that fold back 180 degrees on themselves. In a modern home or apartment, these types of hinges are used on a pair of doors between the lounge and dining room or a pair of external doors into the garden. When folded out the hinges resemble a butterfly.
Single and Double Action Spring Hinges
Single and Double Action Spring Hinges are hinges that incorporate a spring action within the pivot knuckle. They are easy to spot due to the size of the knuckle, which is usually around double the size of a standard hinge to allow the spring to be built inside. Single action hinges operate in only one direction, like a standard hinge, and the double action hinges operate in two directions, meaning the door can open both ways.
Storm Proof and Cranked Hinges
Storm Proof and Cranked Hinges are most often associated with timber windows. The traditional design of a window where the sash closes over the frame is called storm proofing and requires a special hinge that is cranked at 90 degrees.
