Sustainable Systems by
Western Window Systems delivers comprehensive sustainability through energy-efficient Low-E, argon-filled dual-pane glass and thermally broken frames that minimize heat transfer and thermal bridging. The company employs sustainable manufacturing, repurposes recycled materials, and uses low-emission glass. Western's products enable homes to achieve National Green Building Standard Emerald, ENERGY STAR, Indoor airPLUS, DOE's Zero Energy Ready Home, and net-zero certifications. Advanced weatherstripping minimizes air leakage for optimal energy conservation.
Vantage Line – Series 8000
Minimal frame.
Future-proof performance.
Western's newest line proves you don't choose form over function. Ultra-thin Euro Groove frames and a high-density polyurethane thermal barrier deliver such strong efficiency that the Series 8000 already meets tomorrow's codes — including ENERGY STAR 7 and current and future California Title 24.
Future-Proof Energy Codes Engineered to meet ENERGY STAR 7 and both current and upcoming Title 24 requirements. HD Polyurethane Thermal Barrier A high-density foam barrier — the latest thermal technology — for superior insulation. Dual Continuous Weather Seal Engineered for high air-tightness, water resistance, and structural performance. Low U-Factors Outstanding performance ratings achieved within an exceptionally narrow frame. More Glass, Less Frame Slim sightlines maximize daylight and passive warmth, reducing reliance on lighting. Recyclable Aluminum Durable, recyclable aluminum frames designed for a long, low-impact service life.
Performance Line - Series 7000
Maximum glass.
Minimum energy.
The Series 7000 family is engineered around energy. Low U-factors, high-performance Cardinal glass, and a true thermal break let it open up enormous walls of glass while still meeting today's toughest energy codes — the strongest efficiency story Western builds.
ENERGY STAR Qualified Select Performance Line products meet the EPA's rigorous ENERGY STAR specifications. 0.30 U-Factor & SHGC Low U-values and solar-heat-gain ratings that satisfy standard residential energy codes. Cardinal High-Performance Glass All-climate coated, argon-filled, low-E glass from Cardinal comes standard on the line. Engineered Thermal Break A true thermal break, designed to NFRC standards, paired with maximized insulated glass. Title 24 — Both Paths Meets California's Title 24 on both the performance and prescriptive compliance paths. Recyclable Aluminum Highly recyclable frames, built to last — efficiency that doesn't end at the energy bill.
Classic Line
Two decades of indoor-outdoor living.
Engineered to last — and to recycle.
The builder's choice for over twenty years, the Classic Line pairs a narrow aluminum profile with stainless-steel rolling hardware and dual-pane low-E glass. Choose standard or thermally broken aluminum — either way, you're investing in a frame that's endlessly recyclable and made to outlast.
Recyclable Aluminum Frames built from one of the most recyclable materials there is — a smaller footprint and less energy to produce. Low-E Insulating Glass Dual-pane low-E glass reflects heat back into the room and helps cut heating and cooling costs. Optional Thermal Break Thermally broken aluminum adds an insulating barrier for noticeably better energy performance. Built to Last Architectural-grade construction means decades of service — and far less sent to the landfill. Tight, Durable Seals Seals that control humidity and moisture while minimizing air leakage around every panel. Title 24 Capable Glazing options that help your project meet California's Title 24 energy code.
Why Western?
Low-E Argon-Filled Dual-Pane Glass
Low-E, argon-filled dual-pane glass, a popular choice for energy-conscious homeowners seeking both performance and sustainability. Benefits include:
-
Improved energy efficiency: Reduces heating and cooling costs by maintaining a stable indoor temperature and minimizing heat loss or gain.
-
Enhanced comfort: Limits drafts and cold spots near windows, creating a more consistent and comfortable living environment.
-
Noise reduction: The dual panes and argon gas help block outside noise for a quieter home.
-
UV protection: The Low-E coating protects furnishings, flooring, and artwork from fading due to ultraviolet light exposure.
-
Reduced condensation and frost: Argon gas and Low-E coatings help prevent moisture buildup, reducing the risk of condensation and frost on the glass.
