When looking to buy windows, doors or a new conservatory, you might be wondering what the difference is between PVC and uPVC. Both PVC and uPVC can be used to make windows, doors and conservatories. All of our products except our aluminium product range are made from uPVC sometimes referred to as PVC-U.
Difference between PVC and uPVC
The windows we sell at Medway Windows and Doors are made from uPVC. We choose uPVC products over PVC products for several reasons.
- uPVC is more rigid and durable than PVC
- uPVC doesn’t flex
- Both uPVC and PVC windows are fire resistant and safe.
- Both uPVC and PVC can be recycled.
PVC stands for polyvinyl chloride. It is a strong plastic. To make it more soft and flexible plasticizers may be added. When having stronger more rigid and durable plastic is desirable, as in the case of windows, doors and conservatories, plasticizers are not added. When no plasticizers are added it is called ‘unplasticized polyvinyl chloride’ or uPVC for short.
