Never start a sentance with "And"?
"uPVC" is that right?
Unplasticised Poly Vinyl Chloride
most use the term PVCu these days
at the start of the use ( many years ago ) it was allways called UPVC, BUT around the start of the 90's ( i know as i was maintaining and installing at the time ) , the manufactures started to call it PVCu
Poly Vinyl Chloride Unplasticised
not much of a difference, though if you speak to the manufacturers you will find they use PVCu
