If you’re looking to buy new windows, then you might have noticed that some window frames are advertised as “uPVC”. But what does it mean? In this blog post, we’ll shed some light by going over the term uPVC. We’ll also discuss how it differs from ordinary PVC.

What is uPVC?

So, what it uPVC? Well, it’s essentially a type of rigid plastic. Since it’s so strong and durable, it’s a good material for window frames, drains and plumbing.

And if you’re wondering what the letters uPVC stand for, then it’s “unplasticised polyvinyl chloride”. That’s quite a mouthful so it’s no wonder people shorten it to just uPVC instead!

What is PVC?

PVC stands for “polyvinyl chloride”. It’s similar to uPVC but not quite the same. For one thing, PVC more flexible than uPVC thanks to the addition of plasticizers, which are a substance that softens plastic. If no plasticizers are added, then you have unplasticized PVC (uPVC), a more rigid plastic.

What’s the difference between PVC and uPVC?

The fundamental difference between these two types of plastic is the use of plasticisers: PVC contains plasticisers while uPVC doesn’t. Plasticisers make PVC more soft and flexible, which means PVC is the perfect material for cables, toys, shower curtains and even clothes. uPVC, in contrast, is hard and rigid, so it’s good for things like window frames and pipes.

Can PVC be used to make window frames?

No, PVC isn’t used to make window frames, as this plastic is too soft. To make window frames, uPVC is used instead, as it’s harder and more durable.

Despite this, you might still see some window frames being advertised as “PVC” – however, this will be a mistake and the manufacturers will have actually meant uPVC.

What are the advantages of using uPVC to make window frames?

uPVC is a great plastic because it’s strong, durable and weather-resistant. This makes its an excellent choice for window frames since the plastic can withstand rain, cold, heat and wind without any problems. Being exposed to the elements all day and night is no problem for uPVC; it can take it all. This explains why this type of plastic is so popular for making window frames. In fact, if you look at any window frame today then chances are it’s made from uPVC. It used to be that most window frames were made from wood, but nowadays it’s more likely to be uPVC, thanks to its durability, strength and weather-resistance. It should also be mentioned that uPVC has excellent insulation properties, thus helping to keep your house warm in the winter and cool in the summer. So, all in all, uPVC is an excellent choice for window frames.
