Mannix

What Mannix does

Mannix Windows, operating legally as American Window Products Corporation, is a privately held specialty manufacturer of custom architectural aluminum windows headquartered at 345 Crooked Hill Rd #1, Brentwood, NY. Established in 1971, the firm has accumulated over 54 years of experience engineering windows for high-rise construction and operates as a vertically integrated design-to-installation provider. In-house capabilities span design consulting, engineering, fabrication at the Brentwood manufacturing facility, and factory-trained installation services offered in both union and non-union configurations.

The company's core product line, Architectural Windows (AW), features premium-grade aluminum frames paired with high-performance glass, certified to top AAMA ratings with life cycle testing for structural integrity, energy efficiency, acoustics, and weather resistance. Custom fabrication is driven by architect-approved shop drawings, supporting new construction and renovation across mixed-use, residential, and commercial high-rises exceeding 50 stories. Adjacent service offerings cover window parts supply, professional installation, and aftercare support, all delivered under the Mannix brand.

Revenue is generated through project-based B2B contracts with enterprise general contractors and real estate developers, concentrated in the New York metropolitan area with a stated continental US service reach. Pricing is quote-based and not publicly disclosed; contracts are structured as multi-year engagements covering materials, manufacturing, and installation. The go-to-market combines a consultative field-sales process targeting developers, building owners, and construction managers with listings on industry platforms (Arcat, Acelab, Procore, Sweets, IndustryNet) and a reference book of marquee NYC projects including 605 W 42nd Street, Hunter's Point South, 1 N 4th Place Williamsburg, and multiple TF Cornerstone and Monadnock developments.

Direct peers

• Graham Architectural Products: Manufacturer of custom architectural aluminum windows and doors for commercial and high-rise buildings, with comparable emphasis on engineered-to-order products, thermal performance, and architect-driven specification. A relevant mid-sized peer competing for similar NYC and East Coast projects.
• Wausau Window and Wall Systems: Custom architectural aluminum window and curtain-wall manufacturer focused on commercial and institutional buildings, including high-rise applications. Comparable in terms of custom engineering, energy-performance focus, and reliance on architect specifications for project wins.
• EFCO Corporation: Manufacturer of architectural aluminum windows, storefronts, and curtain walls for commercial construction with a long presence in the NYC high-rise market. Closely overlaps with Mannix in product line (custom aluminum window systems), customer base (large GCs and developers), and specification-driven sales motion.

Broad incumbents

• Kawneer Company (Arconic): One of the largest North American manufacturers of architectural aluminum building products, including window, storefront, and curtain-wall systems used on high-rise commercial and institutional buildings. Operates at far greater scale than Mannix with multiple plants and a national sales/spec force; directly competes for specifying roles on the same types of projects.
• Oldcastle BuildingEnvelope (CRH): One of the largest North American suppliers of architectural glass, aluminum storefronts, curtain walls, and window systems serving commercial and high-rise construction. Competes aggressively on price, scale, and the ability to bundle glazing with frames for large GC and developer clients.
• YKK AP America: Major global supplier of commercial aluminum fenestration systems (windows, storefronts, entrances, curtain walls) with strong North American presence serving developers and GCs on high-rise work. Overlaps with Mannix on product specification and large-project delivery, but at meaningfully larger scale.
• Pella Corporation (Commercial): Pella's commercial division produces architectural aluminum windows and curtain walls for hotels, universities, and high-rise projects. While Pella is best known as a residential brand, the commercial segment overlaps with Mannix on larger custom aluminum fenestration work.

Emerging players

• Schüco USA: German-based manufacturer of high-end aluminum window, door, and façade systems with a growing US presence in premium commercial and high-rise projects. Competes with Mannix at the upper end of the specification spectrum on energy-efficient, design-driven commercial towers.
• Reynaers Aluminium: European manufacturer of high-end aluminum window, door, and façade systems with growing US commercial presence, including on high-rise residential towers. Targets design-forward projects where architect-specified premium systems are required, putting it in direct competition with Mannix at the specification stage.
• Vitrocsa: Premium Swiss manufacturer of minimalist aluminum sliding window walls used in luxury high-rise residential and mixed-use towers. Competes for ultra-premium NYC trophy projects where architectural statement windows are a key differentiator, similar to Mannix's luxury/high-end positioning.
