Both sashes move, and they tilt in so you can clean the outside glass from inside.

Cranks open up to 90 degrees for ventilation, then closes tight against the frame.

Bay, bow, and special-shaped combinations. Framing holds the projection. Flashing keeps it dry.

Horizontal sliders, awning, and single hung when the wall wants a different motion.
You can feel air moving near the frame, or the room by the window never warms up.
Condensation trapped inside the glass means the seal between the panes has failed.
Windows that stick, will not stay up, or will not lock.
Heating and cooling working harder every season often points to the openings.
