Notes
Re-verified September 19, 2026. Corrections: warranty rebuilt from Kolbe's November 2025 Express Limited Warranty (finish terms now distinguish prorated AAMA 2605 30-year coverage from 20-year AAMA 2604; glass term now split by size; transferability and labor exclusion confirmed); replaced an unverified list of specific wood species with Kolbe's own description; product link now points to the WD LINE page. Note: this warranty also governs the Kolbe Ultra and Forgent records, which should be re-checked against it. Performance data is style- and glazing-specific — check the NFRC label
