When to Choose Replacement Double-Hung Windows
Bedrooms
Enhance comfort with effortless operation and excellent ventilation. Easily control the temperature and fresh air by opening either the top or bottom sash independently.
Living Rooms
Create a custom look that complements both modern and traditional aesthetics. We offer custom meeting rail heights, allowing for unequal sash sizes to achieve unique design and exceptional curb appeal without sacrificing function.
Kitchens
They are a top choice for placement above counters or kitchen sinks, as they offer convenient access for ventilation and do not obstruct the view or outdoor area when opened.
Bathrooms
Perfect for balancing natural light and privacy. Their adjustable ventilation is essential for controlling humidity and maintaining air movement in smaller, high-moisture rooms.

Effortless Operation
Every window is built with custom-calibrated balancers to ensure smooth, fingertip operation, easily lifting and lowering even the largest Acclaim™ double-hung windows.

Window cleaning becomes simple and safe. The sashes conveniently tilt-in toward your home's interior, allowing you to easily wash both sides of the glass from inside without climbing ladders.

Frequently Asked Questions
A single-hung window is characterized by a permanently fixed upper sash, meaning only the lower sash can slide up to provide an opening. In contrast, double-hung windows are designed so that both the upper and lower sashes are fully operable. This dual functionality offers homeowners superior ventilation and control, and they are easily used as a replacement option for any existing single-hung unit.
