We are building a modern home in CO (strong sun) and the plan calls for black framed windows (inside & out). Architect said that Jeld-wen has a product that is black vinyl exterior that would be best for the look we need. If not Jeld-wen, then it would need to be a commercial grade aluminum window (much pricier). I spoke with a builder and she recommends Windsor windows - just painting the jambs & frames black...but I'm wondering how much upkeep this would need? Looking for thoughts/advice. Torn on what direction to go. Jeld-wen seems ideal, but I am concerned about the black vinyl fading...
