Andersen offers so many categories of windows that consumers may have difficulty determining the differences between them. This guide will help you understand Andersen’s new-construction and replacement windows.

Materials and Reputation

When shopping for Andersen windows, you will have an option of several different materials, as well as product line categories. Andersen offers windows using wood, a composite material called Fibrex (a mixture of wood fibers and thermoplastic polymers), vinyl, aluminum, and fiberglass. Unlike other window manufacturers who may offer windows with solid vinyl or fiberglass construction, Andersen windows generally use either solid wood cores with vinyl, aluminum, or fiberglass cladding; or frames made solid composite/Fibrex. Andersen windows consistently get high marks for quality. In their 2021 findings, consumer insights leader, J.D. Power, reports that the replacement division, Renewal By Andersen, received a score of 886 (out of 1,000), ranking them the highest in the manufacturer segment.
