2. Higher Cost

  • Production from energy-intensive materials increases manufacturing costs
  • Reflects in higher market prices compared to alternatives like PVC or wood


Aluminum alloy doors and windows offer a balance of advantages and disadvantages that cater to specific project requirements. While they excel in strength, corrosion resistance, and aesthetic appeal, issues with sealing and higher costs should be carefully considered.
