Versatile design and quality materials

The lower sash can be raised to let in fresh air, while the upper sash is fixed. This window features equal glass sizes, a design element that streamlines fabrication and enhances the window's traditional good looks. It is available in cottage or reverse cottage sash styles.

The "family" design of this window series means it can be fabricated into many different configurations by using sashes and supplemental lineals from within the window profile group.

A mark of superior quality, color-stabilized, in-house vinyl formula adds outstanding stain, fade, and impact resistance to our windows.

Our window systems are independently tested and audited for certification by the American Architectural Manufacturers Association (AAMA) and the National Fenestration Ratings Council (NFRC). They also meet or exceed Energy Star® standards. Learn more about our partners.
