The short answer is there’s no difference between the two acronyms, but you’ve probably ended up on this page to get a better explanation than that.

What Do They Mean?

uPVC stands for Poly Vinyl Chloride un-plasticised and UPVC stands for the same but in a different order. Poly Vinyl Chloride is a lightweight but still robust kind of plastic used in a lot of different kinds of consumer goods. The ‘u’ as in un-plasticised simply means that the material hasn’t been softened during the manufacture ensuring that the material will retain its strength and robustness.

The material is commonly used within the home improvement sector, especially in double glazing where uPVC- or UPVC Windows (whichever you prefer) are becoming increasingly popular due to high performance and improving aesthetics.

Why the Change?

The acronym ‘uPVC’ changed to ‘uPVC’ in the early 1980s when the European standards changed the acronym to create a universal naming convention because most languages pronounce the ‘PVC’ before the ‘u’. In writing ‘uPVC’ has proven to make more sense as well because starting a sentence with a capital letter rather than a lowercase one appears more accurate. Many installers and homeowners still refer to uPVC double glazed windows and doors and as such, manufacturers such as Quickslide will understand and refer to the material under both uPVC and UPVC windows.

However, homeowners should be aware that uPVC- and UPVC windows are not two different kinds of products. uPVC (UPVC) windows can easily be identified by its lightweight and robust profile allowing it to withstand even the harshest weather conditions. Unlike timber, uPVC (UPVC) will last for years with no rotting or warping and alongside that there is virtually no maintenance except from a wipe down with a cloth and soapy water every so often.
