The new Western Window Systems Water Management Sill

PHOENIX, Ariz. – Western Window Systems returns to the NAHB International Builders’ Show (IBS) in Las Vegas, Nevada this year with two new products added to its robust portfolio of windows and doors that bring indoor and outdoor spaces together.

The Series 7665 Pass-Through Window, part of the Performance Line, will launch at the homebuilding show in Central Hall Booth C4525. Shown in Bronze Anodized, the product is designed for installation above a countertop, connecting a home’s indoor and outdoor kitchen or dining spaces.

The pass-through window, much like an awning window, features a continuous top hinge for a sleek profile. Its gas struts, when closed, remain completely hidden, reducing visual obstruction compared to similar models from competitors. These gas struts ensure smooth and consistent operation, complemented by a single-point locking mechanism and a modern pull handle for added convenience.

Series 7665 Pass Through Window

“The 7665 Pass-Through Window enhances the indoor-outdoor living experience that’s become a top feature for both new construction homes and R&R projects,” said Brian Leizerowicz, Vice President of Sales for Western Window Systems. “Additionally, the window is designed to merge performance and energy efficiency to deliver great benefits to homeowners.”

Also launching at IBS this year from Western Window Systems is the Water Management Sill. The new floor-level sill option creates a more seamless indoor-outdoor transition, while still providing maximum water management performance. The flush design allows continuous flooring between tracks to eliminate the bulky look of a traditional floor-level sill.

“When specifying large multi-sliding doors, architects and builders are often forced to choose between a streamlined look and water performance,” said Kevin Vilhauer, Vice President of Engineering for Western Window Systems. “The new Water Management Sill makes both possible. Its flush design features a hidden drainage system that moves water out and away from the glass door opening for improved weatherability in exposed areas.”

The Water Management Sill is currently available as an option for the Series 7600 Multi-Slide Door and will roll out to other Western Window Systems products in the future.

In addition to the two new products, Western Window Systems will also have its popular Series 600 Fixed Window on display in the booth. The window now features a new narrow T-bar configuration that offers more glass with less frame to create striking glass walls and wide-open sightlines.
