About Marvin Signature™ Coastline Windows

Previously known as SIW

For homeowners living in the path of hurricanes and tropical storms, Marvin Signature® Coastline windows and doors provide a combination of peace of mind and aesthetic pleasure few products can match.

That’s because Coastline products are designed to be beautiful, yet built for strength and durability. Every Coastline window features the highest quality impact glass and frames engineered from thick, extruded aluminum, to deliver maximum protection against high winds, beating rain and flying debris. Unsurprisingly, Coastline products meet the most stringent building code requirements in North America.

Coastline gives you plenty of options to work with, too. Awning windows, casement windows and specialty shapes are just some of the many products in the Coastline portfolio. And you can customize your windows through an extensive array of design options.

As your local, independent Marvin® dealer, Coastal Sash and Door is proud to offer Coastline windows and doors (previously known as SIW).  Available window options include:
