AirCell™ Fusion Insulated Technology

Quanex’s advanced AirCell™ Fusion Insulated Technology is a proprietary process that helps to dramatically improve thermal performance in vinyl profiles. Compared with conventional window insulation techniques, AirCell technology can help reduce complexity in your manufacturing process while enhancing the performance of your window systems.

Using an exclusive, tri-extruded manufacturing process, AirCell ensures insulated, corner-welded windows that provide superior thermal performance. Windows made with AirCell Fusion Insulated Technology are proven to block thermal conductivity six times better than fiberglass, four times better than rigid PVC and three times better than wood for energy efficiency that is up to 15% better than hollow vinyl. The result is an insulated window that reliably keeps the elements at bay and helps you achieve today’s and tomorrow’s stringent performance standards.


  • Dramatically improved thermal performance for vinyl profiles
  • Eliminates the need for manual foam filling, streamlining your manufacturing process
  • Helps your systems meet next-generation performance standards
