Energy Efficiency

Products that are good for our partners and our planet.

Built into every Western Window Systems moving glass wall and window is a belief that your design ideas, not energy or structural limitations, should determine the look of your project. That’s why our products address energy and structural requirements while promoting the thin profiles and large expanses of glass that have made Western Window Systems a centerpiece in so many residential and commercial projects.

Because our products are completely customizable, you can select or combine options that meet your project’s performance requirements.

Glass & Glazing

Insulating Glass

Western Window Systems products feature low-E, argon-filled, dual-pane glass, which blocks heat loss to the outside while reflecting heat back into a room. This helps to reduce heating and cooling costs. Glass can be customized in a variety of types, colors, and thicknesses to meet the performance challenges of various climates.

Cardinal Glass

Western Window Systems’ Series 7000 family of performance-based door systems and windows come standard with all-climate coated or high-performance glass from Cardinal Glass Industries. Customized glass 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 through installation.

Energy Star

Energy Efficiency and Sustainability

To receive ENERGY STAR certification, a window or door must meet a set of energy performance levels determined by the U.S. government. ENERGY STAR criteria varies in different areas of the country. Select products from Western Window Systems Series 7000 performance-based family meet rigorous ENERGY STAR specifications.

Materials and Performance

Thermally Broken Aluminum

Many Western Window Systems door systems and windows are available with the option of thermally broken aluminum, which features an insulating barrier that increases energy performance.

Weatherstripping

Our door systems feature tight, durable seals that help control humidity and moisture and minimize air leakage.

Air, Water, and Structural Performance

Western Window Systems’ door systems and windows are subjected to air, water, and structural testing and are tested and certified by the NFRC (National Fenestration Research Council) and AAMA (American Architectural Manufacturers Association).
