Kitchens and Bathrooms
The crank opens the window over a sink or tub without a stretch or a step stool, and the full opening clears steam and cooking heat fast.

One crank opens the whole sash to the breeze
Side-hinged glass that swings wide, seals tight, and catches air other windows miss.
A casement window is hinged on the side and opens outward with a crank, the way a book opens. The whole sash swings clear of the opening, so the window can scoop in a breeze and aim it into the room. Closed, the locks pull the sash tight against the frame on all four sides. JBN Windows measures the opening, checks the swing outside, and helps you compare the glass, frame, and hardware that fit the room.
The best location begins with where the breeze should land
A casement is a side-hinged sash on a crank, built to open fully and seal completely, with no rail across the middle of the glass.
That makes it a natural choice over a kitchen sink, where the crank works and lifting a sash does not, in bathrooms that need steam out, and in any room where the window has to move real air. It is also the style that opens wide enough to serve as a bedroom exit where the code asks for one.
We still need to look at what happens on both sides of the wall. Counters set the reach to the crank, walkways and AC units sit in the swing path outside, and the direction the sash opens decides whether it catches the breeze or blocks it.
One sash that opens all the way
The design earns its keep when a room needs real airflow and a tight seal from the same window, at the same time.
The crank opens the window over a sink or tub without a stretch or a step stool, and the full opening clears steam and cooking heat fast.
A casement opens its whole frame, so it can meet bedroom exit sizes that hung windows meet only at much larger sizes. We check the numbers at the visit.
The sash needs its arc outside. A walkway, deck, or AC unit tight against the wall can rule this style out for that opening.
We can look at the room, the reach, and the outside clearance before you choose.
The flank panel on bays and the partner to fixed glass
Casements are the working half of the classic combinations: the flanks of a bay window, the sides of a wide picture window, the opening half of a wall that is otherwise fixed glass. The center carries the view and the casements carry the air, in both directions.
The hinge side is a real decision. A sash hinged to catch the evening breeze off the yard cools the room. Hinged the other way, it can block that same breeze. We set the hinge side by the yard, the wind, and the furniture, not by habit.
Browse picture windows for the fixed center of the wall and bay and bow windows for the projection these panels flank. For a top-hinged partner over or under fixed glass, compare awning windows.
The crank and hinges carry the whole design
A casement is not ordered from one measurement across the center. We check width and height at multiple points, look for square, inspect the sill and surrounding wall, and confirm how the existing unit was installed.
The hardware is part of the size. A casement sash hangs off one side, so its weight sets the honest limit on width and height. The crank, the hinges, and the locks all carry that sash for decades, and the screen sits inside where it stays clean.
Size availability varies by manufacturer, product series, frame material, glass, and configuration. JBN Windows works factory direct with Pella, Andersen, and MI Windows. We compare what can actually be made for the opening rather than promising every size in every material.
A window that opens fully still has to seal completely
A casement closes by pulling the sash against the frame at several lock points, so the weatherseal compresses the same way all the way around. That is why this style tests so well against wind and driven rain for a window that opens. The glass still has to suit the wall, since a wide-open sash on a west wall takes the full afternoon sun.
The NFRC label rates the complete window. U-factor measures heat transfer. Solar Heat Gain Coefficient tells you how much solar heat passes through. Visible Transmittance helps compare daylight. A lower SHGC can help with solar heat, but it can also change the appearance and brightness of the glass.
ENERGY STAR certification is useful, but it does not replace comparing the exact product and wall exposure. We do not promise a fixed utility-bill reduction. Review the official ENERGY STAR explanation of NFRC ratings.
The glass is only as good as the opening around it
Before removal, we protect the nearby floor and create a safe handling path. Once the old unit is out, the exposed opening is checked. Damage, poor drainage, or an out-of-square condition should not be hidden behind a new frame.
The replacement unit is set level, square, secured, insulated, and sealed according to the selected product and installation method. Interior and exterior finish work is completed as described in the proposal. We run the crank, check the locks and the seal with you, clean the work area, and review the finished window together.
Manufacturer warranty coverage depends on the exact brand and product line. We review the applicable written warranty instead of promising a universal lifetime warranty for product and labor.
A straightforward process for a window on a crank
We look at the room, the reach, the swing outside, and where the air should land.
We check the opening and compare available frames, glass, colors, and combinations.
The selected window and surrounding installation work are documented before ordering.
The unit is installed, sealed, cleaned, inspected, and walked with the homeowner.

Straight answers before you put a crank in the wall
It is hinged on one side and opens outward with a hand crank at the base. The whole sash swings clear of the frame, and the screen sits on the inside, so the opening is the full size of the window.
Yes, they are among the tightest-sealing windows that open. The locks pull the sash against the frame on all sides, so the weatherseal compresses evenly. Actual performance still depends on the complete product and the installation, so compare the exact NFRC ratings.
Yes, and it is the most common pairing we install. Casements flank the fixed center pane, or form the side panels of a bay, so the wall gets the view and the airflow from the same unit.
Smaller than most styles, because the sash hangs from one side and its weight rides on the hinges. Maximum size depends on the manufacturer, series, frame material, and glass. The opening must be measured before an available size is confirmed.
They are the best ventilating window per square foot. The whole sash opens, and angled outward it can catch a side breeze and direct it into the room instead of letting it slide past the house.
Often, yes. Exit rules set a minimum clear opening, and a casement opens its full frame, so it can meet the size at a smaller window than a hung style. We measure and check the numbers at the home visit.
Written warranty terms depend on the selected manufacturer and product line. We review the applicable warranty and state any JBN Windows workmanship commitments in the proposal.
No. We come to your home to inspect the room, the opening, and the swing outside.
