Awning Windows

The sash on an awning window is hinged at the top of the frame, and the bottom swings outward. Some awning windows are pushed open and pulled closed manually with a handle, while others are operated with a hand crank. Awning windows that are wider than they are tall are often installed higher up on a wall to preserve privacy or usable wall space. They can also be installed above doors or larger windows to improve ventilation, pull in more natural light, and maximize views.

Awning windows excel at bringing in a cool breeze and letting stagnant hot air flow out of a room. Because they open at the bottom, awning windows naturally shed water, so it may be possible to keep them open in wet weather. Like casements, awning window are energy efficient because the wind blowing on them can actually create a tighter seal.

Bay & Bow Windows

Bay Window

A bay window is most often comprised of a larger center window with two narrow windows on either side. The narrow windows are installed at an angle, which causes the bay to project out beyond the exterior wall.

A bow window also projects beyond the exterior wall, but bow windows are typically comprised of four or more similarly sized windows, which creates a curved rather than angular effect. Bow windows require more space than bays.

Both bay and bow windows can be created by building individual rough openings into the wall to accommodate standard sized windows, or they could be mulled (connected) together at the factory and then shipped and installed as one large unit.

Bay and bow windows are popular because they can open up a room, add natural light, and provide three-dimensional views. They can also serve as a cozy reading nook with bonus storage built under the seat.

Casement Windows

A bay window is most often comprised of a larger center window with two narrow windows on either side. The narrow windows are installed at an angle, which causes the bay to project out beyond the exterior wall.

A casement window sash is hinged on the side and opens either to the left or the right. Some casement types are pushed open and pulled closed manually with a handle, but most are operated by a hand crank usually located on the lowest part of the window frame. Crank operated windows are a great option in kitchens and bathrooms where cabinets or a bathtub may prevent access to the upper portions of the window. This type of window typically has a modern aesthetic. A more traditional style can be achieved by adding divided lite bars, also known as window grids.

Because there is only one sash, casement windows can deliver large, uninterrupted expanses of glass. When closed, they prevent air infiltration better than any other type of operating window. When open, they are effective at capturing a breeze, and screens stay cleaner longer because they’re located on the inside of the glass. Also, when fully open, the sash on a casement window barely obstructs the opening. In the case of an emergency, this larger space allows residents to evacuate through a smaller rough opening than would be possible with other style windows.

Corner Windows

Kitchen with a corner window

A corner window is a single unit comprised of two or more sashes that meet at a corner and span both sides of a building. A corner window requires a special framing method in order to create a rough opening with no corner support. Eliminating large support structures opens up the entire corner to sweeping panoramic views with minimal visual disruptions and captures light from multiple directions. Corner windows create a clean and modern aesthetic, but do not operate.

Double Hung Windows

A double hung window has two operable sashes that move up and down. The sashes slide in tracks built into the frame and are held in position by either counterweights, springs, or friction. The sashes are locked shut with a latch located where they meet in the middle. Double hung windows are associated with a more traditional aesthetic and often have simulated divided lights, or window grids installed. A double hung window that has a top sash narrower than the bottom sash is sometimes called a cottage window.

Double hung windows have certain advantages over single hung windows, which have a stationary top sash. Double hung windows are an easy type of window to keep clean because both sashes tilt in for easy access to the inner and outer surfaces of the glass. Lowering a top sash allows heat to more easily escape from a room. Also, if a window is located directly below a projecting eave, lowering the top sash may still be an option even during a rainfall.

Picture Windows

Picture windows are large fixed windows that create the effect of framing outdoor scenery like a picture frame. Because picture windows do not operate, they’re often paired with windows that do. Picture windows can be assembled with or without a sash. Windows without a sash, also called direct glaze windows, can provide larger unobstructed views.

With their large size, picture windows invite in expansive views and an abundance of warm, natural light. And because there are no moving parts, picture windows are more energy efficient than operating windows of a similar size. Its unique, forward thinking design delivers large unobstructed views but can also capture a breeze and provide all the health benefits associated with fresh air.

Picture Specialty Shape Windows

Windows that are not in the shape of a rectangle or square are considered picture specialty shape windows. Picture specialty shape windows are available in hundreds of geometric shapes and provide virtually unlimited design possibilities. Most custom-built picture specialty shape windows have a fixed sash, meaning they don’t open, and many are found near to or combined with operating windows.

Single Hung Windows

Single Hung Windows

A single hung window is virtually indistinguishable from a double hung window. Both have an upper and lower sash, and just like a double hung, a single hung window is easy to operate and provides a traditional aesthetic. The primary difference is that the top sash does not operate on a single hung window, while both sashes operate on a double hung.

A single hung window could be an ideal choice in areas where a top sash would be hard to reach. Because the top sashed is locked in place, single hung windows prevent more air infiltration and are more energy efficient. Also, single hung windows can be less expensive than double hung windows.

Sliding Windows

Sliding windows, also called gliders, operate like double hung windows except the sashes move to the right and left instead of up and down. Sliding windows could have one or multiple operating sashes or be combined with picture windows. The operating sashes on sliding windows can either tilt in, swing in, or be removed for easy cleaning of both sides of the glass.

Sliding windows provide large unobstructed views, plenty of ventilation and are perfect for large horizontal spaces. And because sliding windows do not open out past the plane of the wall, they’re perfect for high traffic areas like decks, walkways or areas where landscaping may be positioned close to the house.

Tilt Turn Windows

Hopper Windows

Tilt turn windows offer European styling and can deliver large unobstructed views similar to a casement window. A tilt and turn has two distinct functions: the top of the sash can tilt in like a hopper window or the entire sash can swing in like a door. With the top of the window tilted in, a tilt turn window can provide topside ventilation and prevent strong winds from blowing objects off tables and countertops. When swung wide open, a tilt turn window can capture even the slightest breeze. They also create a large egress opening for occupants to escape through in case of an emergency. The swing function also enables access to both sides of the glass for easy cleaning.

Bedroom with windows

The sash of a hopper window is hinged at the bottom and tilts into the home. It is operated with either a crank or a handle. Because the only access to outside is a smaller opening at the very top of the window, hoppers provide effective fall protection. Hopper windows feature top-side venting, which is an efficient way to clear a room of hot air. Hopper windows create a distinctive architectural aesthetic.
