A butt hinge consists of two leafs, each with three or four knuckles, and pins, which join to create a barrel that is curved, known as the knuckle. The knuckle or barrel, houses the hinge's pivot point and is usually secured to the leafs using screws or other fasteners.
One of the major advantages of butt hinges is their capacity to accommodate heavier loads over other hinges. This is due to their bigger knuckle provides more support for leafs. In addition the hinges on butts are able to handle more expansion and contraction, making them more resistant to extreme temperatures.
Moreover Butt hinges are designed to be installed in recessed areas. This means that they aren't visible when the door is opened or closed. This gives a smoother appearance and a more refined look. However, they might require routing to achieve a flush finish.
Butt hinges come with a disadvantages. For instance, the amount of friction they create can wear down the hinge over time. It is recommended that hinges are regularly cleaned and lubricated to prevent the chance of this. This will help prevent friction from destroying the knuckles and ensure they are working efficiently.
Some butt hinges reduce friction by using the ball bearing between the knuckles. They are great for doors that see frequent use. 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 plain bearing with grease that reduces friction by allowing the hinge to move with minimal force. They are ideal for lighter uses, including cabinet doors. These pins are also available with spun-ends to ensure that the pin is permanently secured in place.
Butt hinges are commonly used in residential settings, but they are also popular in industrial and commercial applications. For instance, they are used in research and medical facilities to shield patients from radiation and neutron contamination and also for vault doors and security systems.

They allow the door to close and open smoothly around the pin or axis connecting the two hinges and distribute the weight of the sash evenly for better performance over time.
Similar to other hinges, butt hinges are available in a range of sizes and load-bearing capacities to handle different door sizes and weights. The kind of hinge you choose will be determined by the purpose for which it is used and the desired level of performance and durability. The load-bearing capacity of a hinge depends on the amount of force that is applied to the hinge, and the length of time that it is subjected to this pressure. A heavier-duty hinge is required for heavy-duty use.

Make sure that the screws that are furthest from the hinge body are anchored to steel reinforcing and plastic instead of the wood of the sash to avoid damage to the sash or the frame. Then, insert the hinge body pin through each of the slots that are used to locate the plate. Secure it using the screws that correspond to it.
For the majority of applications, a standard uPVC will require x3 hinges.
