A butt double glazed window hinge is made up of two leaves with three or more pins, knuckles, and a barrel with a curving. The knuckle or barrel is the pivot point of the hinge. It is usually attached to the leaves by screws.

Butt hinges are able support heavier loads than other hinges. This is due to their larger knuckle offers more support to leafs. In addition the hinges on butts are able to handle more expansion and contraction, which makes them more resilient to extreme temperatures.

Additionally they are designed to be placed in recessed surfaces. They are not visible when the door is closed or opened. This results in a smoother appearance and a more refined aesthetic. It is possible that they will require routing to create a flush finish.

To prevent this from happening it is recommended to regularly clean and lubricate the hinges. This will stop friction from causing wear on the knuckles and ensure they function smoothly.

Some butt hinges reduce friction by putting a ball bearing in between the knuckles. These hinges are ideal for doors that require heavy-duty, high-use. They also come with a pin that is fixed which is ideal for doors that cannot be opened by removing the pin.

Other types of replacement hinges for upvc windows include a plain bearing with grease, which reduces friction and allows the hinge to be moved with minimal force. These hinges are ideal for applications that require less force, such as cabinet doors. These pins can also be purchased with spun-ends, which ensure the pin is permanently secured in the correct position.

Butt hinges are found in commercial and residential locations.
