AirCell™ Fusion Insulated Technology for Windows


The AirCell™ technology used in Quanex Building Products’ EnergyCore™ window systems is a patent-pending process that drastically improves thermal performance over hollow and manually foam-filled vinyl. Using an exclusive, tri-extruded manufacturing process, AirCell™ technology ensures fully insulated, corner-welded windows that provide superior thermal performance.

Windows made with AirCell 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 percent better than hollow vinyl.
