Designer tip: I have liked the Integrity line of fiberglass windows from Marvin for few years now. And...they come in black! For that old fashioned farmhousey yet hip and fresh modern look. Also did you know that for about $150 per window, Marvin makes single glaze old fashioned style storm windows? This is how you get to triple glazed on moderately sized windows without a heavy chunky window unit. or how you forgo replacing all those beautiful old double hung windows in your 1920's foursquare.
