Series 670 Hinged Window Line
The Series 670 hinged window line offers the styles, sizes, and performance features to enhance any type of home. Combining clean design and optimal performance with the same commitment to superior craftsmanship found in our multi-slide and bi-fold doors, the Series 670 window line can be integrated with our hinged doors, sliding doors, and fixed window walls for maximum views and ventilation.
Designed with a 4.5” frame depth, the Series 670 can be directly mulled to most of Western Window Systems’ product lines such as hinged doors, sliding doors, and fixed window walls.
For improved water drainage, each window style in the Series 670 line includes a sloped sill.
