Double-hung windows feature two independently operable sashes — the top lowers and the bottom raises — giving you flexible ventilation control. This makes them ideal for Houston's transitional seasons, where you want airflow without fully opening a window.
One of the biggest advantages of double-hung windows is how easy they are to clean. Both sashes tilt inward toward the room, so you can wash the exterior glass from inside your home — no ladders or exterior access needed. This is especially useful for second-floor windows.
Royalis Windows installs double-hung windows in a range of frame materials and finishes. Each unit is custom-measured to your existing opening, ensuring a tight weatherseal that keeps Houston's heat and humidity outside where it belongs.
