Front heated windscreen demisting in banding

Hi Guys, 

I have a 2012 ford focus Mk 3. I have a strange issue with the heated front windscreen. It appears as though the front windscreen is demisting/defrosting in bands. leaving large sections of the windscreen untouched. 

The bands aren't on any particular side and the bands are vertical. They are spread thickly and thinly over the whole window?

The sections that defrost/demist do so at a very quick pace, the other sections never do. It gets to the point that the blower defrosts/demists these bands before the windscreen ever does. 

Anyone got any ideas as to where I can start with this one?

    Some of the elements that run vertically through the windscreen are damaged. There is no way to repair them.

    On the mk1 the common conductor for them used to become damaged where the wipers swept, resulting in one complete side not demisting. This was sometimes repairable but I'm afraid as Ian says, you need a new windscreen.

    This was also an issue on the MK2.
