Learn the difference between Casement and Hung Windows
When it comes time to replace your home’s windows, one of the first questions you’ll be asked is, “What style windows are you interested in.” There are lots of choices, so knowing how these two popular window styles operate can help you make the right decision. It pays to learn what the differences are before you make a decision.
Hung windows open and close vertically by sliding the sashes up or down. Single hung sashes have a fixed top sash and a lower operable sash. Double hung windows have two operable sashes. While both types offer good air ventilation control, double hung windows allow a user the option of opening either the top or bottom sash. The meeting rail limits full visibility, so if your view is a top priority, a casement may be a better option.
You’ll find that most recently manufactured hung windows are designed to tilt in (tilt-latches) so that both the interior and exterior of the window can be cleaned from inside the home.
Hung windows are traditional in style. They’re often found in pairs or combined with other window styles.
Casement windows are hinged on one side and swing outward. This allows them to open fully for maximum ventilation. Unlike hung windows, the hinge mechanism doesn’t require a minimum width so they can be used in narrow spaces.
Casement windows offer maximum visibility because they are singular windows. However, they are limited to a height of 72″ since the weight of the window is fully reliant on the hinges when open.
They aren’t as easy as tilt-latch hung windows and require an unobstructed space outside the window. Large bushes or shrubbery could prevent the window from fully opening, and a pathway could become impassable when the window is opened.
ENERGY EFFICIENCY
Both hung and casement windows are energy efficient. They can be made with double or triple-pane glass, and well-made window units will rate as high as R5 or R6 in full window performance.
