WHAT IS THE COST/BENEFIT RATIO OF PVC WINDOWS?

PVC windows provide net cost advantage both in buying and along their life span. Wooden windows are approximately 20-50% more expensive than the PVC windows; aluminum windows on the other hand are the most expensive and 30-70% more costly as an alternative.   They are the cheapest alternative in short and long term considering minimum maintenance as base for the duration of their service time of 50 years and high energy saving potential.
