Product Specs

Metal, Aluminium
Opening types

With a design pressure (DP) rating tested for the commercial marketplace and the ability to be glazed on the inside for easy installation, our single-hung and sliding windows are perfect for projects from luxury hotels and resorts to office spaces and modern homes.

A thermally broken aluminum option makes the Series 610 and 620 energy-efficient. And because each is designed to integrate with our large sliding glass doors and fixed windows, there are nearly infinite ways to customize. 

Clean Design

Engineered for smooth operation, maximum ventilation, and a modern aesthetic, our single-hung and sliding windows are designed with premium hardware and a 4.5” frame depth.

Mulling Options

Both window styles can be directly mulled to most of Western Window Systems’ product lines such as hinged doors, sliding doors, and fixed window walls. This male/female mulling feature is unique in aluminum fenestration products and eliminates the need for operable inserts while maximizing glass and narrowing sight lines.

Locking System

A positive-acting T-lock engages an integrated strike in the frame’s center bar. Available in black and brushed nickel finish.


After-market screening solutions are available from Wizard Screens. Screening is not available through Western Window Systems.

Tested for Durability

Because we build and test our windows to last, you can enjoy your Western Window Systems product for years to come. Manufactured in the U.S., each of our product families is tested for air, water, and structural performance and certified by the NFRC (National Fenestration Rating Council) and AAMA (American Architectural Manufacturers Association).

Climate Ready Glass

We use dual-paned low-E glass for better energy performance. Glass can be customized in a variety of types, colors, and thicknesses for improved privacy, protection, and thermal efficiency.
