Types of Hinges for uPVC Doors

If your uPVC door is dangling or falls, it could be because of the hinges. You may have to replace or adjust the hinges of your uPVC door in order for it to operate smoothly.

Hinges are comprised of hinge leaves (or flat plates), knuckles and a hinge pin. They permit compression and lateral adjustments.

Butt Hinges

There are many different kinds and sizes of hinges. Each has its own unique features to meet different requirements for installation. Butt hinges provide strength and durability to doors. They are also available in a wide variety of styles and finishes to complement the appearance of the door or the installation area. There are also hinges that are available to accommodate unique needs such as pivoting hinges, or fully concealed barrel hinges.

A butt hinge is comprised of two leaves with three or more knuckles, a pin and a curved barrel. The knuckle, or barrel, is the pivot point of the hinge. It is usually attached to the leaf using screws.

One of the primary advantages of butt hinges is their ability to accommodate heavier loads than other hinges. This is because of their larger knuckle, which offers more support for the leafs. Butt hinges are more resistant to extreme temperatures as they have more capacity for expansion and contraction.

Butt hinges can be installed on recessed surfaces. This means they're not visible when the door is opened or closed. This creates a smooth appearance and a more refined aesthetic. However, they could require routing to achieve an even finish.

Butt hinges come with their own set of drawbacks. For example the amount of friction they produce can cause the hinge to wear out over time. To prevent this from happening, it is recommended to regularly clean and lubricate the hinges. This will stop friction from wearing down the knuckles and ensure they are functioning efficiently.

Some butt hinges reduce friction by putting a ball bearing in between the knuckles. These hinges are great for heavy-duty, high-use doors. These are also available with a pin that is fixed, making them ideal for doors that can't be opened by removing the pin.

Other types of butt hinges include a grease-packed plain bearing, which reduces friction by allowing the hinge to move with minimal force. These hinges are best suited for light-weight applications like cabinet doors. They also come with spinned ends to ensure the pin is permanently fixed in the correct position.

Butt hinges are found in both residential and commercial environments. For instance, they are used in research and medical establishments to shield patients from contamination by neutrons and radiation, as well as vault doors and security systems. They are also essential for the military and defense sector in which they are used to secure armored vehicles and transporters. Brass or stainless steel is commonly used to improve durability and resistance to corrosion.

Flag Hinges


A hinge is a bearing that joins two parts and allows them to move around the fixed point. Hinges are generally constructed of metal and are available in a variety of sizes, styles, and weight capacities to fit various applications. They are employed on many different objects, including doors, lids and enclosures. They are available in a variety of finishes to match any aesthetic. There are several kinds of hinges that are commonly used on doors and uPVC windows; these include flag, butt and continuous hinges.

They are designed to be placed between the door frame and sash, creating an elegant, minimalist appearance when closed. They allow the door to open or close easily around the pin that connects the two hinges. They also distribute the weight of the sash evenly over time for more efficient performance.

Similar to other hinges, butt hinges are available in a variety of sizes and load-bearing capacity to accommodate different door size and weights. The purpose and the desired level of durability and function will determine the type of hinge to be selected. The capacity of the hinge for carrying loads is determined by the quantity and duration of pressure applied to it. A hinge that is stronger-duty is needed for applications that require a lot of force.

Flag hinges are a standard kind of hinge for doors, and are suitable for a variety of door sizes and applications. They tend to be smaller and lighter than other types of hinges, making them suitable for use on doors that are lightweight. They are also very sturdy and can withstand heavy forces making them a good option for high-traffic areas.

To install the flag hinge first, you need to mark the locations of the pin-locating holes as well as screw holes on the door sash as well as the hinge body. With the fixing jig drill these holes prior to the time you attach the hinge plate to the sash, ensuring that it is in line with the profile. Make sure that the screws that are furthest from the hinge body are secured into plastic and steel reinforcing instead of the wood of the sash to avoid 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. Attach it using the corresponding screws.

For most applications, a standard uPVC will require x3 hinges. The top flag hinge should be placed 150mm higher than the top edge, and the bottom, middle and outer hinges must be evenly spaced between them. To verify the correct placement of the hinges, a door sash should be shut and raised to its maximum height, and you should be able see the hinges in their full length when fully raised. If not, the hinges are probably too far apart, and the door will not be able to function properly or safely.
