In this video, Ken explains the difference that little ‘u’ actually makes. It stands for ‘unplasticised’, meaning the heavy metals and harmful additives found in older PVC formulations have been removed. The result is uPVC: a stronger, more stable and more durable material that’s better suited to your home. So, while it might be just one little letter, it makes a big difference when it comes to creating a safer, longer-lasting product you can feel good about having in your home.
