Casement windows are one of the most practical and energy-efficient window styles available to Tulsa homeowners. Hinged at the side and operated by a simple hand crank, a casement window opens fully outward — giving you maximum ventilation, a clear unobstructed view, and a tight weatherproof seal when closed. Tulsa Window Pros installs casement windows for homes across the Tulsa metro area.
If you’re replacing older windows that stick, rattle, or fail to seal properly, casement windows are worth serious consideration. Their single sash design and compression seal mean they outperform double hung windows on air infiltration — an important factor in Oklahoma, where summer heat and winter cold both put pressure on your home’s envelope.
Why Casement Windows Work Well in Oklahoma
Oklahoma summers are hot, humid, and often still. Casement windows are designed to catch and funnel cross-breezes in a way that other window styles can’t match. Because the sash opens fully and projects outward at an angle, it acts as a scoop — directing moving air into the room even when the breeze is coming from a slight angle rather than head-on. On cooler spring and autumn evenings, that natural ventilation reduces reliance on air conditioning and makes the home more comfortable without any running cost.
In winter, the compression seal on a closed casement window creates a tighter barrier against cold air than the sliding seal on a double hung unit. Less air infiltration means less heat loss and a more consistent indoor temperature. Combined with a low-E glass coating and an argon gas fill between the panes, a modern casement window performs well against Oklahoma’s temperature extremes in both directions.
Casement Window Styles and Configurations
Casement windows can be installed as single units or paired side by side for wider openings. A paired casement configuration — sometimes called a French casement when the two sashes open outward from a central point with no fixed mullion — creates a wide unobstructed opening that works particularly well in kitchens, living rooms, and any space where you want to maximise both airflow and the view.
We install casement windows in standard and custom sizes to fit existing openings without structural modification in most cases. Frame materials are typically white or colour-matched PVC for low maintenance and long-term performance. All units we install meet NFRC performance certification standards.
Casement Window Installation in Tulsa
Our installation process starts with precise measurement of the existing opening. We order the unit to fit, remove the old window cleanly, fit the casement unit level and square, seal the perimeter correctly, and test the crank mechanism and seal before we leave. The job is typically completed in under an hour per window.
