uPVC is an ideal replacement for wood in many instances. For example, it can be used to create window frames that are more durable and able to better withstand the elements compared to wood. Regular PVC is not used to create window frames. This is because uPVC will not decompose, but regular PVC might. Regular PVC is also not as weather-resistant as uPVC is. For certain heavy-duty draining and plumbing, those working on construction might also use this material instead of cast iron.
