Re-verified September 19, 2026 against Marvin's current site. Corrections: Marvin's site now presents Ultimate as its own collection (the old 'Signature' collection URL was replaced); style list corrected to Marvin's current list (tilt-turn and French casement removed as they are not on the current Ultimate page); natural-wood exterior option added; warranty PDF link updated to the January 2026 document; labor exclusion and 60-day claim window added. Performance data is style- and glazing-specific — check the NFRC label
