Capitol is more than a product supplier. Our team works with architects and engineers during project development to help evaluate systems, develop details, understand performance requirements, and move a concept toward a buildable specification.
Custom architectural detailing & engineering support since 1956
Tailored head, jamb, and sill details built for your exact openings
Over 90% of our work is dedicated to educational facilities.
Up-to-date Division 8 specification language
Bring Capitol into your early schematic design process to eliminate pre-bid guesswork, performance gaps, and costly value-engineering redesigns. Working alongside your design team before details are locked down, our in-house experts provide custom CAD details, simulated thermal performance, hardware recommendations, and budget estimates. We don’t replace your design authority—we support it with specialized product and manufacturing expertise right when it matters most.
Our sales and engineering staff assist with standard and custom architectural details, helping teams coordinate thermal breaks, structural wind loads, and perimeter anchorage requirements early in design.
Identify cost drivers early. We evaluate frame profiles, practical aesthetics, and glazing infills to provide realistic budget models that align with district budgets and project goals.
Avoid field surprises on aging structural openings. Our experience manufacturing and installing replacement architectural windows, doors, storefronts, and curtain wall systems helps us anticipate existing-opening conditions, masonry tolerances, flashing transitions, and structural interfaces.
School entrance security is paramount. We assist in hardware recommendations and coordinating access controls. We offer impact-resistant FRP and Flush doors, safety & security film with attachment system, and bullet resistant glass integrations.
Optimize SHGC, U-Factors, and STC sound ratings for optimal classroom learning environments. We help select glass types that reduce solar heat gain while maximizing daylighting.
Access current CSI 3-Part specifications for Capitol products, ready to include in your Division 08 project manual.
Rigorously tested to AAMA, ASTM, and NFRC standards, providing the reliable performance metrics and system criteria you need for your design submittals.

Capitol's sales and engineering team partners with architects as new school projects take shape, helping evaluate systems, performance goals, and design details.
Review window, curtain wall, storefront, and entrance options for design intent, performance needs, and how systems work together across the building.
Use product data, CSI 3-Part specifications, CAD details, and available performance information to build a coordinated basis of design.
Work through openings, framing interfaces, finishes, and transitions to adjacent wall assemblies while design details are being developed.
For the new Willard K–12 School, Capitol Aluminum & Glass was subcontracted by Adena Corporation to provide and install a comprehensive range of architectural aluminum windows, doors, storefronts, and curtain wall systems. From classroom windows to the building's main entrances, the project brings durable, consistent glazing throughout the new school—contributing directly to its official LEED Silver certification.
Upgrading aging school infrastructure demands more than standard replacement methods. Between occupied facilities, summer break completion deadlines, and strict budget parameters, you need a manufacturing and installation partner who gets it right the first time.
We begin by understanding your project's scope, aesthetic vision, and functional requirements. From there, we laser-measure existing masonry openings to design precise trim requirements, provide tailored budget proposals, and bid specifications.
Capitol's sales and engineering staff bridges the gap between historic or existing school layouts and modern performance standards, ensuring design intent remains uncompromised from concept to final installation.
Plan for masonry tolerances, concealed conditions, and transitions between new windows, doors, storefronts, and curtain wall systems, and existing wall assemblies.
For the renovation of this 1913 Tudor Gothic landmark, Capitol Aluminum & Glass partnered with SSOE Group to develop custom S-curve signature windows and a coordinated package of aluminum windows, entrances, storefronts, and curtain walls. Close design collaboration, mockup review, and custom fabrication helped preserve the school's architectural character while restoring daylight and addressing project-specific thermal performance requirements. Capitol also provided documentation supporting the project's LEED goals.
Support your project’s LEED certification goals with Capitol’s windows, doors, storefronts, and curtain wall systems.
Supplier documentation identifies pre-consumer and post-consumer recycled content, helping project teams evaluate sustainable sourcing and applicable LEED Materials and Resources credits.
Fabricated and assembled in Bellevue, OH, helping midwest school construction projects meet regional sourcing thresholds.
Thermal breaks and low-E glass assemblies balance daylight access with thermal performance.
Capitol’s aluminum systems and supporting product documentation helped these project teams earn LEED credits toward certification.
