Replacement Bow Window Styles

Marvin Replacement Bow windows, built with the strength of Ultrex fiberglass frames, accentuate a home's existing curves. Our bow windows are available in four, five or six-wide window configurations with flanking casement windows to add a graceful arc to your home's style. The assembly gently bows outward to create a focal point of your home.

The windows can all have the same width or have a wider middle window than the flanking windows. Customize your bow window with standard pine or optional oak veneer head and insulated seat boards.

Exterior Colors

Our finish stands up to the elements, so much so that 48,000 hours of sun can't fade our finish* and our fade-resistant acrylic finish resists scratches, chalking, chipping, denting, and peeling. Choose from seven stunning exterior colors to boost your curb appeal.

Marvin's Ultrex® fiberglass finish is verified to the American Architectural Manufacturers Association (AAMA) 624 specification. Achieving AAMA 624 verification means that our Ultrex finish has passed rigorous tests that simulate the harsh conditions a finish can encounter throughout the life of a window or door.

Glass Coatings

Our experts will walk you through energy efficient glass options to find the right selection for your home and the best windows for your climate. Choose from four glass coatings, plus decorative glass options, and specialty glass choices.

Low E-1

Primarily used in colder climates, Low E1 allows more heat in to warm a room while blocking heat loss.

Low E-2

Low E2 offers year-round performance in moderate climates. It will help retain heat in your home during the winter and keep heat out during the summer.

Low E-3

Low E3 rejects solar heat while letting light in, resulting in increased performance in climates with intense sun exposure.

Low E-3/ERS

Low E3/ERS provides maximum efficiency year-round in all conditions.

Specialty Glass

We offer specialty glass to best suit the needs of your home. You can choose tempered glass, laminated glass, and STC/OITC glass for specific windows and rooms.

Tempered Glass

Tempered glass increases glass strength to help prevent breakage. Tempered glass is ideal for windows close to the floor or located in high-traffic areas.

Laminated Glass

Even more durable than tempered glass, laminated glass is often referred to as impact resistant or safety glass due to its vinyl inter layer that tends to remain in place when shattered.

STC/OITC Glass

Sound Transmission Class and Outdoor-Indoor Transmission Class glass has increased pane thickness on the room side and works in areas where exterior noise is a concern.

Divided Lites

We offer various divided lite patterns so you can replicate the look of your original windows and doors. Or, add new architectural interest to your home. Choose from Simulated Divided Lites for classic appeal or Grilles-Between-the-Glass for easy cleaning.

Casement windows can come with a Simulated Checkrail to create the look of a double hung window with the functionality of a casement. Patterns include: Cottage, Prairie 2-Wide, Prairie 2-Wide 6-Lite, Prairie 9-Lite, Simulated Checkrail, and Standard Pattern.

Frequently Asked Questions

Bay window vs. bow window?

A bay window typically has three windows or openings, while a bow window will have four, five or six windows or openings. An easy way to remember the difference between a bow and a bay window is that a bow window resembles the arc of a bow. A bay window will have operable windows at each end of the picture window while each window can be operable in a bow window.

Do bow windows open?

Yes, each unit in a bow window can open as we use casement windows for our bow windows.

Added Assurance

Marvin Replacement windows and patio doors come with a limited lifetime warranty as well as a 5-year installation warranty to provide additional peace of mind.
