Historic-Replica & Steel-Replica Aluminum Windows & Storefronts
Boyd Aluminum manufactures historic-replica and steel-replica aluminum windows and storefront systems for commercial restoration, adaptive reuse, and historic-review projects.
Boyd's historic windows provide modern performance with a classic steel look. Boyd aluminum systems help replicate the appearance of historic steel windows and storefronts while supporting today's commercial building requirements.
Historic restoration projects often require careful attention to existing openings, narrow sightlines, grid patterns, muntin configurations, glazing requirements, storefront proportions, and the intended architectural appearance. Boyd offers fixed, operable, projection, casement, and storefront options for commercial restoration and replacement applications.

How to Choose a Historic-Replica or Steel-Replica System
Historic window and storefront selection starts with the existing opening, required operation, intended appearance, glazing requirements, grid or muntin pattern, storefront scope, finish requirements, and review expectations for the project.
Fixed openings: Review fixed historic-replica or steel-replica systems when the opening does not require operable sash.
Projected openings: Review project-in or project-out configurations when ventilation, sash operation, and historic appearance must be coordinated together.
Casement openings: Review casement configurations when the project requires side-hinged operation, hardware coordination, and historic steel-window appearance.
Storefront conditions: Review historic storefront framing when the project includes storefront proportions, entrance coordination, glazing requirements, and architectural appearance requirements.
Common Historic Window and Storefront Coordination Issues
Historic restoration and adaptive-reuse projects often require more coordination than a standard replacement window or storefront project. Review these items early so the selected system matches the drawings, existing conditions, and review expectations.
Existing openings: Field conditions, opening sizes, substrates, and surrounding construction can affect system selection and detailing.
Sightlines and profiles: Historic-review projects may require careful coordination of frame proportions, sash appearance, storefront proportions, and visible aluminum profiles.
Grids and muntins: Grid patterns, muntin configuration, spacing, and visual alignment should be reviewed before final product selection.
Glazing and finish: Glazing makeup, bead style, finish selection, and color expectations should be coordinated with the project specifications and review requirements.
Review authority expectations: NPS, SHPO, local historic-review boards, owners, architects, and contractors may each require different supporting details or submittal information.
What to Send Boyd for a Historic Project Bid
To help Boyd review a historic-replica or steel-replica window and storefront request, send as much of the following information as available:
Project name, location, and bid deadline.
Architectural drawings, elevations, and window or storefront schedules.
Existing opening conditions, field dimensions, photos, or restoration constraints.
Desired operation type, such as fixed, projected, casement, or storefront framing.
Glazing requirements, finish requirements, grid patterns, muntin requirements, and hardware expectations.
Any NPS, SHPO, local historic-review, owner, architect, or specification requirements available for the project.
Can Historic-Replica Aluminum Windows Be Used on NPS or SHPO-Reviewed Projects?
Boyd Aluminum's historic-replica and steel-replica aluminum window and storefront systems can be reviewed for commercial restoration projects subject to National Park Service (NPS), State Historic Preservation Office (SHPO), or local historic-review requirements. Approval requirements are determined on a project-specific basis by the reviewing authority and depend on the submitted assembly, jurisdiction, existing conditions, and project scope.
Boyd helps architects, contractors, and owners evaluate product options, profiles, system depths, details, glazing requirements, and specifications for historic restoration work involving NPS or SHPO review.

Historic Window & Storefront Questions
What is a steel-replica aluminum window?
A steel-replica aluminum window is an aluminum window designed to reproduce the narrow sightlines, grid or muntin patterns, and visual profile of historic steel sash. Boyd Aluminum's historic-replica and steel-replica product families, including the 3250XT-G family, Series 6200, Series 6300, Series 6400, and BH01 Historic Storefront, are used on commercial rehabilitation, adaptive-reuse, and historic-review projects where the steel-window appearance must be coordinated with modern commercial building requirements.
What is the difference between true divided lites, simulated divided lites, and applied muntins?
True divided lites use separate panes of glass divided by muntins; simulated divided lites and applied muntin grids recreate that appearance over larger glass. Which approach fits depends on the historic pattern being matched and the project's review expectations — see Boyd's architectural muntin systems for the full comparison and applied muntin options.
Do replacement windows qualify for the federal historic tax credit?
Replacement windows can be part of a certified rehabilitation, but tax-credit treatment is determined through the National Park Service review process. NPS does not pre-approve a manufacturer's window product. Review typically focuses on documentation of the existing windows and how the proposed replacement matches the size, configuration, profiles, sightlines, muntin pattern, glazing character, materials, and overall appearance. Boyd Aluminum can support project teams with drawings, details, and product documentation for review; final qualification is determined by the reviewing authority, not by Boyd.
How do aluminum replica windows compare to steel windows for historic projects?
Aluminum replica windows give a project the look of historic steel, including narrow sightlines and matching muntin patterns, in a modern commercial aluminum system. Compared with traditional steel sash, aluminum replicas are generally lighter, resist corrosion, and can incorporate thermal breaks and insulated glass for better energy performance and lower long-term maintenance. Steel remains the original material and can achieve very thin sightlines, which can matter on strict historic reviews. The right choice depends on the appearance the reviewing authority requires, the opening conditions, and the project's performance and budget goals. For a project-specific comparison, send elevations and existing-window details to Boyd's Direct Assistance team.
