          Energy Efficiency
In addition to a .34 U-value for standard low-E, argon-
filled dual pane glass, our operating window line boasts
a signature aluminum extrusion design utilizing custom Insulbar technology that further reduces energy consumption. Windows are NFRC-tested and comply with California’s Title 24 requirements.
The Series 7610 Single-Hung and Series 7620 Sliding Window test units received a performance rating of CW-PG50. A frame depth of 5.875” supports triple-pane, laminated, and security glass — essential options for noise reduction. Currently in testing for hurricane impact.
Locking System
A positive-acting cam lock engages an integrated strike in the frame’s center bar. Black finish only.
Heavy Duty Hardware
For strength and smooth operation, Western Window Systems uses premium hardware for its windows.
All fasteners are stainless steel.
Climate-Ready Glass
For solar control and high visibility, our operating windows come standard with Cardinal IG’s all-climate coated or high-performance glass. Glass can be customized in a variety of types, colors, and thicknesses. Options include laminated glass, solar- and glare-control glass, enhanced winter performance glass, and Neat low-maintenance glass. Pre-applied Cardinal Preserve film protects glass
during installation.
Screens are manufactured from extruded aluminum and employ an easy-to-use concealed clip system. Screen frames are finished to match the window’s frame color.
Colors are available in-stock or as designer selections. They can be customized to match nearly any color. For approximate finish options, see page 130. For exact paint swatch samples, contact us.
