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.


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 One-High, Prairie Four-Lite, Simulated Checkrail, Prairie Six-Lite, Prairie Nine-Lite and Standard Rectangular.

Frequently Asked Questions

Awning vs. casement windows

Awning and casement windows have a lot of similarities. Both are windows that open out to a home exterior, but they differ in how they swing open. Casement windows open horizontally with a hinge on the side while awning windows open vertically with a hinge at the top.

Our Awning and Casement windows feature a tuckaway handle to provide uninterrupted views. Both can provide ample natural light and ventilation.

You can typically find awning and casement windows in bathrooms or kitchens where you need more ventilation. Both windows require enough exterior space so they can open and close easily.

What rooms work best for casement windows?

Casement windows often appear in kitchens because they can provide plenty of ventilation, which is important when cooking. Casement windows also can also appear in bathrooms to help with ventilation. Dens or sitting rooms can also often have casement windows to catch a breeze and natural light.

How do casement windows open?

Casement windows have a hinge on the side to open outward to the left or to the right. They open by rotating a crank usually in a clockwise motion. Marvin Replacement also has an option ClearView® hinge to maximize views.

Casement windows vs. double hung windows

Casement windows provide uninterrupted views because they don’t have a check rail like double hung windows. Marvin Replacement Casement and Double Hung windows can be cleaned from the inside of your home for easier cleaning.

Double hung windows can provide more design elements with simulated divided lites or grilles between the glass options.

Choosing casement windows vs. double hung windows can come down to their location. It can be tough to reach the top sash of a double hung window in places like above a kitchen sink while casement windows need space outside your home to swing open.

How do casement windows lock?

Our Casement windows have a multi-point locking system to create a tight seal to prevent wind and weather from entering.

Do casement windows have screens?

Casement windows typically have a screen on the interior side of the window to allow free movement of the window.

What are the benefits of casement windows?

Casement windows can provide more ventilation than double hung windows and fit well in spaces where reaching to lift a single hung or double hung sash is difficult.

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.
