I have read many posts about windows, but none about our specific situation, so hopefully you all can help us. We need black exterior windows and sliding doors for a new construction modern home. We were considering Sunrise windows with the reviews on this forum, but we live in Colorado where I have been told that black vinyl will not hold up because of sun exposure. The cost of black vinyl in Sunrise would be the same as aluminum clad. Our architect and contractor are pushing us toward aluminum clad, but we would like to hear the opinions of the good folks here. Budget is a concern, but not to sacrifice low maintenance and performance. Thanks-
