How do you measure for uPVC doors?

In order to ensure a good fit for your new uPVC door, it is essential to have the doorway accurately measured by your installer. There are many factors to be mindful of when measuring. You need to get the height and width from the outside opening correct as well as taking into account the plaster thickness inside and the floor height too.  For glazed rear doors including bi-folds or French Doors, getting the right size is essential to be certain that the doors open and close correctly and provide access.
