Double-Hung vs. Casement Windows: Pros and Cons

How The Two Styles Work

A double-hung window has two sashes that move vertically, so you can open the top, the bottom, or both in many designs.

The opening style affects airflow, screen placement, exterior access, and how easy the glass is to keep clean.

The best choice is rarely the one that looks best in a showroom alone.

Which Style Fits Your House And Your Budget
