Double Hung Window Replacement & Installation
What Are Double Hung Windows?
Double hung windows are the most popular choice for replacement windows — and for good reason. What sets them apart from other window styles is simple: they have two independently movable sashes, one on top and one on the bottom, both of which can slide up and down within the frame.
This is what distinguishes them from their close relative, the single hung window, which looks identical but has only one operable sash (the bottom). With a double hung, you have full control over both.
Feldco offers high-quality double-hung replacement windows, including the Sophia Series, which features enhanced energy efficiency, durability, and smooth, easy operation for everyday use.
Easy to Clean
Both sashes on a double hung window tilt inward, letting you clean the exterior glass from inside your home. This eliminates the need for a ladder or juggling cleaning supplies outside. A quick wipe-down from the comfort of your own room is all it takes to keep the glass looking its best.
Built-In Safety Features You Can Rely On
Double hung windows come with one or two interior locks (depending on window size), securing the sashes so they can't be forced open from outside. They also include ventilation latches — stops located on the inside of the frame that limit how far a sash can travel. This lets you keep the window open for air without compromising security.
Superior Air Circulation in Every Room
Because both sashes move independently, you can fine-tune airflow in ways a single hung window can't match. Opening the top sash lets warm air escape near the ceiling, while opening the bottom draws in cooler fresh air — a natural ventilation effect. You can also open both sashes at once for maximum airflow throughout the home.

Ideal Locations for Double Hung Windows
Double hung windows are versatile enough to work in any room of your home, in any size, style, or color you need.
- Bedrooms – Good ventilation control and safer airflow from the top sash.
- Living rooms – Balanced airflow and a classic, versatile look.
- Kitchens – Fit well above sinks/counters where outward-opening windows won't work.
- Bathrooms – Provide ventilation and privacy when frosted glass is used.
- Upper floors – Safer operation and easy partial opening for airflow.
- Historic / traditional homes – Matches classic architectural styles and preservation needs.
Double-hung windows may not be the best choice in certain situations where other window styles perform better:
- Wide view spaces – they can interrupt a clear, open view with a center rail.
- High airflow needs – casement windows usually allow stronger natural ventilation.
- Modern minimalist designs – fixed or frameless styles create a cleaner look.
- Large or hard-to-reach openings – sliding windows are easier to use and maintain.
- Vent-heavy utility areas – outward-opening windows improve airflow and exhaust efficiency.
