What to Consider Before You Install Casement Windows

Casement windows are hinged windows that swing open outward, typically operated with a crank. They're popular for offering unobstructed views and their tight seals when closed. If you're considering installing casement windows, here are some important things to consider.

Insulation & Air Leakage

One of the biggest advantages of casement windows is how well they seal. Because the sash closes against the frame with compression (rather than sliding shut like a double-hung window), multi-point locking hardware pulls the sash tight at several points around the frame. This closing pressure creates a more consistent seal than you'll typically get from sliding window styles. 

Air leakage ratings tell you how much air passes through a closed window. Lower numbers mean a tighter seal. Better ratings can result in lower heating and cooling demands, but keep in mind that your actual energy performance also depends on several factors. These include your HVAC equipment, the quality of your window installation, and everyday habits (such as how often you open your windows). 

Materials & Hardware

Frame material and hardware quality both affect how a casement window performs over time.

• Frame material (vinyl, fiberglass, wood, or clad options) affects durability, maintenance needs, and appearance. Vinyl frames are common for their low maintenance and good insulating properties.
• Hardware matters more with casement windows than with most other styles. Stainless steel hardware is a strong choice because it resists corrosion.
• Manufacturing origin can be worth asking about. Windows engineered, tested, and manufactured in-house (rather than assembled from third-party parts) tend to have more consistent quality control.

Keep in mind that even good materials perform only as well as the overall product design, installation, and maintenance allow.

Design & Layout Options

Casement windows can be installed as standalone units or combined with other styles, including bay, bow, picture, or awning windows. Together, they can create a larger, coordinated window arrangement. Handle style and sash shape are worth considering, too, as they can complement your home's exterior without competing with it.

Before finalizing a layout, think through:

• Opening dimensions and how they fit the exterior proportions of your home
• Interior furniture placement and available wall space
• Clearance needed for the sash to swing open fully (especially important for casements, since the sash projects outward)

If you're planning a multi-window arrangement, our team at  can help you balance these factors and get the solution that works perfectly for your needs. 

Views & Ventilation

Casement windows have no center meeting rail (the horizontal bar that splits the glass in a double-hung window), so they offer a nearly unobstructed view and let in more natural light.

For ventilation, many casement windows open to a wide angle and, because the sash projects outward, can actually help catch and direct outside air into the room. 

That said, how much airflow you actually get depends on:

• Where the window is placed relative to prevailing wind
• Whether screens are installed
• Nearby landscaping, structures, or other obstructions

Energy-Efficient Glass Packages

We offer 3/4-inch dual-pane insulated glass and 1 1/8-inch triple-pane insulated glass. Both configurations use multiple panes to reduce heat transfer compared with single-pane glass, while the warm-edge spacer system supports the seal and energy performance of the insulated glass unit.

Dual-pane and triple-pane packages give Mechanicsburg homeowners different configurations to consider based on the opening, exposure, and desired glass construction. When selected as part of a compatible package, low-E glass can reduce solar heat gain and glare. Actual window performance also depends on the frame, installation, orientation, shading, and condition of the surrounding opening.

Depending on the selected configuration, our glass packages can meet ENERGY STAR® requirements in all four climate zones. We can explain how the available packages compare, but actual household energy savings vary.

Lifetime Casement Window Warranty & Service

Others promise a lifetime warranty, but the fine print really limits your coverage. At , we provide a true lifetime warranty, and it's one of the best in the industry. 

The warranty transfers to a new owner at no charge. We also provide free lifetime service labor for covered warranty requests and 24-hour personal assistance for warranty service. Our comparison of nearly 100 competitor warranties focuses on coverage homeowners frequently need to verify, including installation labor, screens, service visits, and transferability.
