Marvin Coastline Picture Narrow Frame is a rectangular picture window. The glass is glazed directly into the frame, eliminating the need for a sash, which results in narrow sightlines, more light, and unobstructed views. It also features a sleek, streamlined frame that will complement any contemporary aesthetic. Unlike vinyl, the aluminum frames on this impact resistant window will not become brittle, distort, or swell when exposed to the sun, extreme heat, and humidity. The Picture Narrow Frame window can withstand high winds and provides unsurpassed protection from flying debris generated by hurricanes and tropical storms.
