When calculating this it’s important to include the weight of any additional ironmongery attached to the door. This can include locks, furniture and door closers. The basic weight of the door should then be adjusted to take into account any special factors. To do this, apply all of the relevant percentage increase(s) from the table below, then multiply them by the basic weight. This will give you the initial adjusted weight.
