What is the difference between uPVC Double Glazed Windows & PVCu Double Glazed Windows ?

There is no difference because it is actually the same thing. uPVC changed it’s name to PVCu (also sometimes seen as PVC-U) in the late 1980s to fall in line with the European market . It is called PVCu  there because most European languages place the noun (the word PVC in this case) before the adjective (U).

The ‘PVC’ part of it stands for Polyvinyl Chloride. The ‘U’ stands for Un-plasticised.

The every day  ‘PVC’ or Poly Vinyl Chloride is modified often to soften it so it can  be used in the manufacture of products such as sport bags and fake leather. It is the use of this material which has made us familiar with the abbreviation ‘PVC’.
