What is a casement window?
Casement windows are one of the most efficient window styles available for Upstate SC homeowners. The crank operator gives you precise control over how much air enters the room, and the wide opening angle makes it a practical choice for both everyday ventilation and emergency egress. With their clean sightlines and versatile sizing options, they complement both traditional and modern home designs beautifully.


What is an awning window?
Similar to a casement window, an awning window opens outward but on a horizontal axis instead of a vertical one. The sash tilts outward from the bottom, allowing fresh air in even during light rain. Like casement windows, awning windows use the same easy crank operation and multipoint locking system. They can also be opened wide to create a convenient passthrough window perfect for entertaining outdoors. If you’ve been looking for awning windows near me that combine style and function, this is an option worth exploring.
Where should I consider installing a casement window?
Casement and awning windows installation in Upstate SC works well in a variety of locations throughout the home. Casement windows fit especially well in hard-to-reach spots like above the kitchen sink, where reaching up to push or pull a sash would be awkward. They also pair beautifully as part of a projecting bow or bay window configuration.
Awning windows are ideal for basement openings, bathrooms, or any spot where you want ventilation without sacrificing privacy or weather protection. The single crank operator opens and closes both window styles with ease, making them a practical choice for any room in the house.

Frequently Asked Questions
What is the difference between a casement window and an awning window?
A casement window opens outward on a vertical axis, like a door. An awning window opens outward on a horizontal axis from the bottom, allowing ventilation even when it’s raining.
Can awning windows stay open during light rain?
Yes. Because awning windows angle outward from the bottom, the frame acts as a canopy that deflects rain, one of their biggest advantages over other window styles.
Do casement windows open a full 90 degrees?
Yes. All of our casement and awning windows open a full 90 degrees, making them easy to clean from inside and compliant with egress code requirements.
Where are casement windows best suited in the home?
Casement windows work great in hard-to-reach areas like above the kitchen sink, in bow or bay window configurations, and in any room where maximum ventilation is a priority.
