Types of Hinges for uPVC Doors

Hinges are made up of hinge leaves (or flat plates), knuckles and a hinge pin. They allow for lateral or compression adjustments.

Butt Hinges

When hinges are concerned, there are countless kinds and sizes available. Each hinge has its own distinct features to meet different installation needs. However, butt hinges are an extremely useful type of hardware that provides the strength and durability needed for doors. They come in a range of finishes and styles that can be customized to fit the design of the door. There are also hinges that are designed to meet the needs of specific customers, such as pivoting or fully concealed barrel hinges.

A butt hinge consists of two leafs with three or four knuckles and pins, which join to form a curved barrel known as the knuckle. The knuckle or barrel, is the hinge's main pivot point and is typically attached to the leafs by fasteners such as screws.

One of the main advantages of butt hinges is their capacity to accommodate heavier loads as compared to other hinges. This is because of their larger knuckle, which provides more support for the leafs. Additionally repairmywindowsanddoors.co.uk on butts are more able to handle expansion and contraction, making them more able to withstand extreme temperatures.

Furthermore they are designed to be placed in recessed surfaces. This means they're not visible when the door is either open or closed. This provides the door with a more smooth appearance and a refined look. They may need routing to achieve a flush finish.

Butt hinges come with their own set of drawbacks. For example the amount of friction they produce can wear down the hinge over time. It is recommended that hinges be regularly cleaned and lubricated to prevent this. This will prevent friction from causing wear on the knuckles and will ensure that they are working efficiently.

Some butt hinges use a ball bearing between the knuckles to reduce friction. They are perfect for doors that are heavy-duty and have frequent use. They are also available with a pin that is fixed which is ideal for doors that are secure and cannot be opened with the removal of the pin.

Other types of butts hinges include a plain bearing that is coated with grease that reduces friction and allows the hinge to be moved without much force. These are recommended for use on lighter items, such as cabinet doors. These pins are also available with spun-ends, which ensure the pin is securely held in the correct position.

Butt hinges are typically employed in residential settings, but they are also popular for commercial and industrial applications. For instance, they are used in research and medical facilities to shield patients from contamination by neutrons and radiation as well as vault doors and security systems. They are also used in the defense and military industry to secure armored vehicles as well as transporters. Stainless steel or brass is frequently used to increase the resistance to corrosion and durability.

Flag Hinges

A hinge is a type of mechanical part that connects two components and allows them to move around a fixed point. Hinges are typically made of metal, and are available in various styles, sizes and capacities of weight for various applications. They are employed on many different items, including doors, lids, and enclosures. They are available in a variety of designs to complement any design. Certain hinges are installed on doors and uPVC Windows. These include butt, continuous, and flag hinges.

Butt hinges are typically used to support the sash of a door and provide the necessary stability for smooth operation and longevity. They are designed to be placed between the door frame, and the sash. This creates a clean, unobtrusive look when closed. They also allow the door to open and close smoothly around the pin or axis that connects the two hinges and distribute the weight of the sash in a uniform manner to ensure better performance over time.

Similar to other hinges butt hinges come in a range of sizes and load-bearing capacity to handle different door sizes and weights. The application and desired level of durability and functionality will determine the type of hinge to be selected. The hinge's load-bearing capability is determined by the quantity and duration of pressure applied to it. A hinge that is stronger-duty is needed for heavy-duty applications.

Flag hinges are a common type of hinge for doors and can be used for a variety of door styles and applications. They are generally smaller and lighter than other hinges, making them ideal for use on doors that are lightweight. They are also extremely sturdy and can withstand heavy force, making them a good option for high-traffic areas.

To install the flag hinge first, you need to mark the location of the pin-locating holes as well as screw holes in the door sash and on the hinge body. The holes are then pre-drilled using the fixing jig then screw the hinge onto the sash so that it is in line with the profile. Ensure that the screws furthest from the hinge body are secured to steel reinforcing and plastic instead of the wood of the sash, in order to prevent damage to the sash or the frame. Next, insert the hinge body pin through each of the slots that are used to locate the plate. Secure it with the screws that correspond to it.


For most applications using standard uPVC will require x3 hinges. The top flag hinge should be located 150mm above the top edge and the bottom, middle, and outer hinges should be placed evenly between them. Close the door sash and raise it to its full height. You should be able see the hinges in their full length. If not, then the hinges may be too far apart and the door will be unable to operate smoothly or securely.
