Philadelphia Casement Windows

Casement Windows Fit Historic Philadelphia Homes

Colonial history runs deep in Philadelphia and is reflected in many of the homes across the Delaware Valley, like the Colonial Revivals in Allentown’s West Park Historic District or the brick Colonials in Wilmington’s Fairfax neighborhood. The city’s booming housing market also includes historic Federal-style row houses and elegant Victorians as well as a number of brand new homes springing up around the greater Philly area. Whether a new home or old, Philadelphia homeowners are enjoying the benefits of casement windows.

Casement windows are hinged on one side and operated by a crank. For this reason, casements are also commonly known as crank windows. Casement windows typically extend outward, and unlike single- and double-hung windows where only one section of the window can open at a time, casements open entirely to provide maximum ventilation.

Commonly known as: crank windows, side hinge windows, side hung windows, hinged windows

Popular Local Trends & Styles

Casement Window Sizes
Casement windows are extremely versatile. They can be tall, narrow rectangles or small, equilateral squares and are great window choices for difficult-to-reach spots, like tight corners or over a sink. Standard casement window sizes vary depending on the window material, but whether you require a large casement window or a small one, casements come in a range of standard sizes to suit the unique requirements of your home.
Casement Window Styles While the majority of casement-style windows open outwards via a crank, there a number of other casement window styles that homeowners adore. French casement windows are one popular style. In this style, two sashes open from the center of the window frame. Another type of casement is a push-out casement window, which, unlike a crank window, operates simply by turning a locking latch on the window and pushing out to open.
Vinyl Casement Windows
Homeowners enjoy vinyl windows for their energy efficiency and low-maintenance qualities and vinyl casement windows are no different. Fully welded sashes are nearly invisible and provide strength and durability. Available in 11 exterior finishes, including a sleek black color, vinyl casement windows can be customized to suit the style of your home.
Wood Casement Windows
If it’s the natural beauty of wood you seek, wood casement windows are available in three Pella product lines. Thanks to the natural insulating properties of wood, these windows also provide excellent energy efficiency. Crafted from Douglas fir, mahogany, or pine, Pella’s wood windows are available in a number of interior and exterior finishes, including a cool, contemporary black, and can even be customized to look like a traditional double-hung window.
