Series 610 Single-Hung and Series 620 Sliding Windows from Western Window Systems can be glazed on the inside for easy installation. Designed with a 4½-inch frame depth, both window styles can be directly mulled to most other Western Window Systems’ product lines, such as hinged or sliding doors. The male/female mulling feature—unique in aluminum window products—eliminates the need for operable inserts. Series 610 is available in widths up to 48 inches and 72 inches in height, while Series 620 has a double-sash option available up to 96 inches in length. Both are available in thermally broken aluminum for better energy performance. westernwindowsystems.com
