Andersen E-Series specialty windows with dual-pane glass are not confirmed as listed for wildfire-area use.

Andersen offers clear dual-pane glass and several Low-E dual-pane choices for E-Series specialty-shape windows. This establishes that the product can be ordered with two panes, but it does not establish how many panes are tempered. The two-pane configuration is a shared glazing attribute, not proof that every glass option satisfies a wildfire requirement or appears on a current product listing.

The distinction matters because clear and Low-E units may share the dual-pane description while remaining different ordered options. The E-Series name and the words “dual pane” do not identify the full glazing construction or settle the tempered-pane count.

Before using one of these windows for a California or IBHS glazing path, confirm the exact glass option on the order and inspect the etched labels on the panes. Those details are needed to establish the glazing actually supplied. Without that confirmation, dual-pane glass alone does not support treating the window as listed for wildfire-area use.
