Why Choose Casement Windows

Casement windows pivot sideways and outward with an internal crank. Their vertical configuration provides a boost in ventilation, allowing fresh air to flow into your house and inside air to move out. A casement window opens more fully than any other type of window, compared to double hung windows in which both halves cannot be opened together, or sliding windows with only one opening side. Here are some other reasons casements are chosen for window installation.

Boston Why Casement

Better Visibility

Many types of windows divide up glass panes with muntins, or strips of wood, metal, vinyl, or fiberglass. With casement windows, these are not necessary unless you desire that look. In that case, fake muntins can be installed. But for the most part, casements provide a wide-open view, since the glass is bordered by the window frame of each sash, with nothing in between.


Open sashes act as flaps to funnel in breezes. Contributing to the ventilating properties of casements, this function takes advantage of how breezes naturally move along a house at acute angles. You can therefore get air to move through your house, which is often difficult.

Ease of Use

Hand cranks make casements easier to use, especially in hard-to-reach locations. By turning a crank, you can open a window above a sink, or one located behind furniture, without getting injured. There’s no need to push a window open or reach up to close it.

Low Maintenance

Casement windows are easy to clean; there are just two big panes of glass to wipe off. Casements are also resistant to fading, chipping, and cracking. Just remember to clean the hinges periodically, as the metal is prone to rusting.

Energy Efficiency

These windows are designed to be energy efficient, and they help regulate temperatures inside. In the winter, casements can increase energy efficiency up to 45%; during the summer, efficiency can be improved by 70%, lowering utility bills all year long. They also let in natural sunlight to provide illumination and warmth.


The locks, which are secured to and embedded within the frames, are shaped like hooks. This design makes casements hard to break into. Also, you can open your windows as wide as you want, with the choice of adjusting the size of the opening to make your home less vulnerable.


When you consider window replacement, casements are in the lower price range compared to double hung and other types of windows. The ultimate price depends on the type of material used for the frame, the size of the window, and if custom options are selected.


Casements are very reliable. Over time, wear and tear might affect the side hinges, so this is something to look out for. The hinges can be easily and affordably replaced. Therefore, you avoid the cost of replacing the window and can maintain its function.
