This window stands out with its welded flat sill, featuring a 5-degree slope that allows for efficient water drainage. In addition, the constant force balance system ensures smooth and effortless operation of the lower sash, making everyday use easy and enjoyable.

The single-hung system is designed to maximize airtightness, with three weatherstrips installed on the sashes, both horizontally and vertically. A flexible bulb weatherstrip placed at the bottom of the sash completes the setup to ensure a perfect seal at the sill. This attention to detail provides excellent protection against drafts and moisture.

The contemporary-style glazing beads, integrated into the sealed units from the inside, feature a flexible co-extrusion that enhances protection against air and water infiltration. Moreover, this design allows for easy replacement of sealed units—all done from the inside of your home—offering unmatched comfort and convenience.
