The casement window system comprises one glass panel hinged at the side that opens outward with a crank. Although the double-hung window is the more popular one, the casement actually preceded it. It only lost its mainstream appeal in the 18th century because the hardware necessary to support a large sash when open wasn’t available then. But now, it’s making a comeback. It may be the oldest form of operating window, but it has proven to be the fittest to meet modern building codes.
In Renewal by Andersen® of San Francisco’s opinion, here are the key areas casement windows fare extremely well:
Ease of Operation
As far as convenience is concerned, the casement is one of your best bets for window replacement. Unlike the double-hung unit’s upper panel that sometimes needs height to open or close, almost every adult can easily operate a casement window. With the turn of a crank, anyone can swing it out or in effortlessly even when it’s installed in a tricky spot, like the sink.
Architectural Authenticity
Despite the dominance of double-hung windows for centuries, some traditional home styles chose to utilize casement units almost exclusively. Prairie architecture is the perfect example.
Further, any savvy windows replacement specialist knows that smart use of grilles could make casement windows appear as double-hung units. If your facade demands sash windows but you love the functionality of crank units, decorating them with a simulated double-hung grille pattern is an elegant solution.
Energy Efficiency
The casement is the most energy-efficient operating window you can buy. Unlike gliding units, its panel presses against the frame on closing, which minimizes air leakage. As a result, it prevents unwanted drafts and traps conditioned, indoor air effectively.
Ventilation
Considering that it only has a singular sash, swinging it completely out makes nearly 100% of the opening useful for natural ventilation. In addition, its panel can be adjusted at any angle, allowing it to control or direct the movement of breezes better than any window.
Egress and Ingress
Compared to multi-sashed windows that only offer limited access when open, this favorite window replacement option has the highest potential for egress and ingress. In case of emergency, it makes for a convenient escape route for your loved ones or a point of entry for the authorities. No wonder why most building regulations require this window style.
