Andersen 400 Series specialty windows with dual-pane glass match one wildfire-related glazing attribute, but that alone does not confirm a listing.

Andersen offers clear dual-pane glass and several Low-E dual-pane options for its 400 Series specialty-shape windows. That establishes that compatible configurations can have two panes. It does not establish how many panes are tempered, and the pane count should not be read as a tempered-glass count.

That distinction matters when relying on a California or IBHS glazing path. The ordered glass option must meet the path’s specific conditions, not merely carry the 400 Series name and a dual-pane description. Check the order details and the etched labels on the glass before treating a particular window as compliant.

The practical answer is therefore conditional: the product description supports an attribute match, not confirmed wildfire-area listing status. Verification needs to follow the exact specialty-window configuration delivered, including its glass option and pane markings.
