What is the difference between uPVC and PVCu?

There is practically no difference between uPVC and PVCu. Both of them refer to unplasticised (hard) PVC, which is used extensively in building products where rigidity is an important attribute. Plasticized (soft) PVC, on the other hand, is used where flexibility is important such as to protect electrical wiring. It is purely a question of jargon and any claims of better performance by uPVC are incorrect.
