The bottom sash moves up to allow air to flow into the home on a Single Hung window and the top sash is fixed.
Geometric windows come in a variety of arched, radius and linear shapes that add visual character to any home’s architecture.
These windows are stationary and do not open. This makes them more energy efficient and allows for larger sizes than a window that vents.

"These windows are excellent. The clean, contemporary look updates our home style and certainly adds value."
