What is a casement window?
A casement window, or a crank-out window, is one of the most convenient and efficient window options available. A casement window opens outward on vertical access by using a crank attached to the sash. The heavy-duty hinges allow you to open the window a full 90 degrees for optimal fresh air and also for convenient cleaning inside and out. Users can easily close the unit tightly with its multipoint locking system and single lever. Casement windows offer a variety of formations including double, triple, or quadruple units. Casement & awning window installation in Delmarva is easy and will add a beautiful window to your home.


What is an awning window?
Similar to a casement window, an awning window opens outward on a horizontal axis. The awning window provides the same features as a casement window but with the window opening vertically from the bottom. Like casement windows, an awning window opens 90 degrees for maximum ventilation and easy cleaning. The awning window can be opened to create a passthrough window for your next gathering too!
Where should I consider installing a casement window?
Casement and awning windows provide an easy-to-use window that allows for optimal light and fresh air. Casement windows fit well in hard-to-reach areas, like the kitchen sink. They are also perfect for a projecting window like a bow or bay. These windows are ideal in many locations because the single crank operator opens and closes the window with ease. If you live in the Delmarva area, awning windows installation or casement style window installation is a perfect option for your home, to increase natural light and ventilation options.
