Vertical Sliding with Classic American Style
The sash slides vertically within the frame, featuring symmetrical proportions and optional divided lites that complement traditional colonial, craftsman, and farmhouse architecture.

Precision Balance System for Smooth Operation
Internal spring or weight balance mechanism counteracts the sash weight, allowing effortless one-hand lifting and holding the window securely at any open height.

Dual Sash for Superior Ventilation
Both top and bottom sashes can be opened independently, allowing warm air to exit from the top and cool air to enter from the bottom for natural convection.

Tilt-In for Easy Cleaning
The lower sash tilts inward from the top, allowing safe and convenient cleaning of both sides of the glass from inside your home without the need for ladders.

Energy-Efficient Weather Sealing
Interlocking meeting rails and compression weatherstripping along all four sides deliver excellent airtightness, water resistance, and sound insulation for year-round comfort.
