Notes
Vinyl. The 1650 is the double-hung MODEL within MI's V3000 Series, not a stand-alone series — MI's own product page (miwindows.com/node/27001) publishes it as "V3000 Series 1650 double-hung windows", with a related 1650 Extreme foam-enhanced variant. Effective January 1, 2026, MI's replacement-product warranty is Lifetime for original owner-occupants and 10 years for later owners; the warranty is transferable. Performance data is style- and glazing-specific — check the NFRC label
