PVCu / uPVC Casement Windows will give you the security, long life and minimal maintenance that you would expect from our highly popular range.

The difference between PVCu and uPVC

It is the same thing, uPVC changed it’s name to PVCu (you may also see it as PVC-U) in the late 1980s to fall in line with Europe.

The Europeans call it PVCu there because most European languages place the noun (the word PVC in this case) before the adjective (U).

PVC actually stands for Polyvinyl Chloride.

Custom made for a perfect fit
