Casement Windows — Maximum Ventilation, Superior Seal
Crank-operated windows that swing fully open for maximum airflow and compress tightly against the frame when closed for an airtight, energy-efficient seal.
What Are Casement Windows?
Casement windows are hinged on one side and swing outward using a crank mechanism, opening the full window area for ventilation — unlike double-hung or sliding windows that only open halfway. This full-opening design makes casement windows the best choice for maximum airflow, and their compression seal mechanism makes them one of the most energy-efficient window types available. When closed, the sash presses tightly against the frame, creating an airtight seal that outperforms the sliding seals used in hung and sliding windows. At Revival Windows, we install casement windows in a variety of sizes and configurations, from single units to mulled pairs and combinations with fixed picture windows.
They’re particularly popular in kitchens (where the crank mechanism allows easy operation over countertops and sinks), bathrooms, and any room where maximum ventilation is desired.
Why Casement Windows Matter for Your Home
The choice of window operating style affects both functionality and energy performance. Double-hung and sliding windows use a sliding seal that allows some air infiltration even when closed. Casement windows use a compression seal — the sash physically compresses against weatherstripping in the frame — that provides a tighter seal and better energy performance.
For homeowners who prioritize both ventilation and efficiency, casement windows deliver the best of both worlds. The full-opening design also makes casement windows easier to clean from inside the home, as both the interior and exterior glass surfaces are accessible when the window is open.

Key Benefits of Casement Windows
Maximum Ventilation
The full window area opens for airflow — double-hung and sliding windows only open 50% of their area.
Superior Energy Efficiency
Compression seals provide a tighter seal than sliding seals, making casement windows among the most energy-efficient types.
Easy Operation
The crank mechanism allows effortless operation, even for windows above countertops, sinks, or in hard-to-reach locations.
Easy Cleaning
Both glass surfaces are accessible from inside when the window is open — no need to remove sashes or clean from outside.
Security
The hook-shaped lock mechanism embedded in the frame is more difficult to force open from outside than standard sash locks.
Design Flexibility
Available in a wide range of sizes and can be combined with fixed windows for custom configurations.
Technical Details & Specifications
Our casement windows feature a multi-point locking system that engages at multiple points along the frame for maximum security and seal compression. The crank operator uses a folding handle that sits flush with the frame when not in use. Hinge hardware is concealed within the frame for a clean appearance.
Available in standard and egress-compliant sizes for bedroom applications. Glass packages include all standard options — dual-pane with Low-E and argon, triple-pane, laminated, and specialty configurations.
What to Expect for Casement Windows
Casement windows carry a modest premium over comparable double-hung windows — typically 10-20% more — due to the more complex crank and hinge mechanism. The exact cost depends on size, glass package, and project scope. We provide detailed quotes during a free consultation so you can compare options and make the best decision for your home.
Every project is unique — that's why we quote on-site, not online. During your free in-home consultation, our window expert will assess your current windows, take precise measurements, and present tailored options with no pressure.

Frequently Asked Questions
About Casement Windows
Can casement windows be used in any room?
Yes. Casement windows work in any room and are available in egress-compliant sizes for bedrooms. They're especially popular in kitchens and bathrooms where the crank mechanism allows easy operation over countertops.
Do casement windows open inward or outward?
Our casement windows swing outward. This maximizes interior space and allows the compression seal to work properly. Screens are installed on the interior side.
Are casement windows more energy efficient than double-hung?
Yes. The compression seal mechanism provides a tighter seal than the sliding seals used in double-hung windows, resulting in less air infiltration and better energy performance.
