Product Introduction
The AMJ 108T Series Single and Double Hung Window is a vertical-sliding aluminum window designed for residential and multi-family construction projects.
It is suitable for houses, apartments, townhouses, hotels, and light commercial buildings. Because the sash moves vertically, the window does not project into walkways, balconies, patios, or interior spaces.
The system usesCaldwell balance hardware for smooth and controlled sash movement. It is available as a single-hung window, double-hung window, or combined with fixed side panels.
Custom sizes, frame colors, glass, screens, hardware finishes, and installation options are available for project orders.
