There are three types of hinges used on uPVC doors:
Flag hinges: Most modern uPVC doors are equipped with flag hinges that allow you to make height, lateral, and compression adjustments. Compression adjustments move the door closer to or away from the door jamb.
T-hinges: These hinges only allow you to make height and lateral adjustments.
Butt hinges: Usually a feature of older uPVC doors, these offer either lateral adjustment only or no adjustments at all. If you have a butt hinge and need to adjust the height, you may need to reinstall your door.
