Q: Which is better, UPVC or Aluminum?

A: Both are good insulating materials, but vinyl is a better choice for a high-energy window because it will not rot, swell, split or be affected in any way by the elements. You will love the aluminum strong and color customized, almost without any of the maintenance.

Custom uPVC windows are relatively affordable, energy efficient, and low maintenance, but may not be as durable as aluminum windows. Custom aluminum windows are strong, durable and weather resistant, but are more expensive and less energy efficient than uPVC. Ultimately, the best window will depend on your preferences and requirements.
