The Fixed Window is the ultimate solution for maximizing natural light and uninterrupted views in both residential and commercial applications. Designed as a non-operable, permanently sealed unit, it eliminates the gaps and hardware inherent in opening sashes, delivering superior thermal and acoustic performance. Our fixed windows utilize advanced thermally broken aluminum technology and precision-sealed insulating glass units to create an exceptional barrier against heat transfer, air infiltration, and external noise. The rigid, sash-less frame supports large-format glass panels, making it ideal for floor-to-ceiling installations that transform walls into panoramic picture windows. Available in powder-coated, anodized, and wood-grain finishes, these windows combine minimalist aesthetics with industry-leading energy efficiency, backed by NFRC and CE certifications.
This article explores why NFRC (National Fenestration Rating Council) certification is the gold standard for aluminum windows and doors in the US market. It covers core energy metrics like U-Factor and SHGC, discusses building code compliance, and explains how thermally broken technology helps homeowners access federal tax credits.
READ MOREWhen a California custom home builder asked if we could produce NFRC-rated aluminum sliding windows, casement windows, awning windows, and sliding doors with shark fin nylon flanges and U-values below 0.30, we said: "Not yet — but we'll invest to make it happen." Six months, $40,000 in tooling and testing, and 120+ technical email exchanges later, we delivered. This is our story of entering the US fenestration market from zero, learning NFRC standards alongside our client, and building a partnership that transformed how we manufacture.
