uPVC (unplasticized polyvinyl chloride) is one of the popular choices for window frames for a long time. As a material uPVC is durable and does not rot over a period of time. Thus, it has a longer lifespan and requires a lesser level of maintenance. The downside is that the frames can degrade over a period of time, however, at a much lower rate when compared to wooden windows. The shelf life is ranging between 20-30 years after which it may require replacement.

Aluminum, on the other hand, is a more robust material and can be used as a window frame for almost an infinite period of time. Aluminum is thus a highly durable material and aluminum of a good quality can last up to 45 years since they do not degrade in the same way as uPVC does. Another advantage with aluminum is that it does not rust, so you can easily render the aesthetic appeal of your property without any rusty patches.
