End Vent Windows

The end vent window design is made to provide gorgeous, panoramic views with sliding windows that are larger than normal. With one fixed window and two moving windows, they offer unhindered sights with maximum ventilation.

Nuts and Bolts

End vent windows are similar to side sliding windows except they have two operational sashes, one at each end of the window, and a fixed window in the center. Some companies offer a center sash that is movable, but most end vent windows have a set center sash.

Both operational, end sashes slide toward the center window, allowing for ventilation on both ends. On some brands, the sliding windows also tilt inward to allow easy exterior cleaning.

Pros and Cons

End vent windows offer uninterrupted views with great ventilation, but there are a few things to keep in mind when considering this type of window.

A major pro for the end vent window is that it achieves the look of a casement window combination at a more economical price. This style of window is also the best option where the slider window is preferred but the opening is wider than 72 inches. Both sashes of an end vent window operate for easy cleaning and maintenance, while the middle makes it possible to produce a wider window.

The downside of the sliders of an end vent window is that they are not as energy efficient as their crank operated counterpart, which can be turned to create as tight a weather seal as possible. If the homeowner gets an end vent window with a fixed center sash, cleaning the outside of the center pane will be a challenge.

Bottom Line

End vent slider windows are ideal for places where out-swinging windows may interfere with landscapes, walkways, decks or patios. These windows are also good for rooms where a wider opening is desired than is available with normal sliders.
