Casement Window Replacement & Installation
What Are Casement Windows?
A casement window is hinged vertically on one side and swings outward from the frame — horizontally toward the left or right, depending on your preference. Unlike double-hung or slider windows that open only partway, a casement opens to its full size, maximizing both airflow and natural light.
Each new casement window is operated with a single-hand crank mechanism. Turn the crank counterclockwise to swing the sash outward; turn it clockwise to close and lock it flush. The low-profile crank handle sits flat against the frame, so window treatments and blinds are never disturbed.
The crank mechanism makes casement windows especially practical for installations where reaching over a surface (like a kitchen countertop) is required. No lifting, no pushing up — just one hand on the crank.
All Feldco casement windows are custom-made to size, manufactured to fit the exact dimensions of your opening, with no filler strips or awkward gaps.
Maximum ventilation, every time you open
The full-open sash channels cross-breezes more effectively than any partially-opening window style. Because the entire frame clears, even a light wind moves freely through the room. No other residential window type matches a casement for raw airflow.
A tighter seal than almost any other window style
When closed, the sash presses firmly against the frame on all four sides simultaneously. This compression seal outperforms double-hung and sliding windows, which rely on friction alone. The result is noticeably better energy efficiency and less outside noise coming in.
Durable vinyl construction that requires zero maintenance
Feldco casement frames are built from high-grade vinyl that resists warping, rot, and fading over years of exterior exposure. There's nothing to paint, scrape, or seal — ever. The material holds its color and shape through Chicago winters and summer heat alike.
How They Work
Residential casement windows come with an easy-to-operate single hand crank, which is painless to use even in the most difficult-to-get-to spaces, such as a new window for kitchen sinks. You can turn the crank counterclockwise to open your window or clockwise to close it.
Ideal Locations for Casement Windows
Casement windows suit a wide range of rooms and openings, but they truly shine in spots where easy operation and strong airflow matter most.
Common installations include kitchens, especially over countertops or the sink, where easy crank operation and strong ventilation help remove heat, steam, and cooking odors. Bathrooms are ideal for improving airflow and reducing humidity and are often placed higher on walls for privacy and mold prevention. Bedrooms are great for maximizing fresh air and cross-ventilation to keep sleeping spaces comfortable and energy-efficient. Hard-to-reach areas such as above bathtubs, behind furniture, or over kitchen counters benefit from the crank mechanism that makes opening simple. Wind-facing exterior walls are excellent for capturing breezes and boosting natural ventilation throughout the home. Select living room spots can also benefit when paired with larger fixed windows to add airflow without blocking views.
