Replacement Window Styles for Rockville Homes

Rockville includes everything from older traditional homes to newer construction, so no single window style works for every property. Alco Products installs a wide selection of replacement windows to accommodate your home’s architecture and energy performance needs, as well as your budget. 

Double-Hung Windows

Double-hung windows are a popular choice for many Rockville homes because of their classic appearance and flexible ventilation options. Both the upper and lower sashes open, allowing homeowners to control airflow throughout the room. Their traditional design pairs well with a wide range of architectural styles, making them a practical option for bedrooms, living areas, and other spaces throughout the home.

Single-Hung Windows

Single-hung windows offer a simple, dependable design that works well for many homes. The bottom sash opens while the top sash remains fixed, providing ventilation while maintaining a clean exterior appearance. Their straightforward operation and classic style make them a cost-effective window option for homeowners looking to update their home's appearance and performance.

Casement Windows

Casement windows hinge on the side and open outward with a turn of a crank. This design creates a wide opening for fresh air while offering a clear, unobstructed view when closed. Casement windows are a great choice for areas where ventilation and natural light are priorities, including kitchens, living rooms, and hard-to-reach spaces.

Awning Windows

Awning windows are hinged at the top and open outward from the bottom. Their design allows homeowners to bring in fresh air while helping keep rain out during light weather. Often used on their own or paired with larger window styles, awning windows provide added ventilation flexibility throughout the home.

Bay Windows

Bay windows extend outward from the home's exterior, creating additional interior space and adding architectural character. Their angled design lets in more natural light while creating a comfortable area for seating, plants, or décor. Homeowners often use bay windows in living rooms, dining areas, and other spaces where they want to make a statement.

Bow Windows

Bow windows use multiple window panels arranged in a gentle curve to create a wider view and a more dramatic appearance. Like bay windows, they add depth to the room while letting in more sunlight. Their rounded design works well with traditional and transitional home styles throughout Montgomery County.

Picture Windows

Picture windows feature a large fixed glass pane designed to maximize natural light and provide expansive outdoor views. Because they don't open, they offer excellent energy efficiency and a clean, modern look. You can also combine picture windows with operable windows, such as casement or double-hung styles, to balance views with ventilation.

Egress Windows

Egress windows meet minimum opening requirements for emergency escape and rescue. They are commonly required in finished basements and below-grade bedrooms. We’ll help determine the appropriate window size and placement for a code-compliant installation.
