Allied Window

What Allied Window does

Allied Window, Inc. is a privately held custom aluminum storm window manufacturer founded in 1950 and headquartered in Cincinnati, Ohio. The company designs, fabricates, paints, delivers, and installs custom interior and exterior secondary glazing systems marketed as "Invisible Storm Windows," serving federal, state, and local government buildings, universities, museums, presidential and historic house museums, adaptive-reuse residential developments, and individual historic homeowners. Its core technology centers on in-house custom aluminum extrusion forming (precision roller bending for arched, bowed, and complex shapes), a state-of-the-art paint facility with about 2,000 custom color matches to date, multiple protective glazing options (laminated, tempered, polycarbonate, low-e), and CSI-formatted Section 8520 specification-compliant product lines across the Historic One Lite (HOL), Allied One Lite (AOL), Magnetic One Lite (MOL), and Slide-A-Way (SAW) families. The product portfolio also includes fixed D-42/D-48 panels, protective variants (PAOL/PMOL), custom screens, and the ARCAT Spec Wizard tool that generates architectural specifications.

The business model is project-based and quote-driven rather than transactional/online. Pricing is not publicly disclosed and is generated per project through a catalog website quote system, with separate commercial ([email protected]) and residential ([email protected]) sales channels, a phone line, and a regional dealer network (e.g., Mozer Works Inc. for the Baltimore/Washington D.C. area). Revenue is generated primarily through one-time custom product sales plus installation services, with a 5-year product warranty and an industry-unprecedented 5-year installation warranty. The company operates its own delivery fleet and nationwide installation crews. Ownership remains private and family-controlled, with Dave Martin as President and Gregg Martin as Vice President; there is no disclosed institutional investor or parent company. Geographic service is domestic (U.S.) across multiple regions, with no international installations.
