Aluminum Curtain Wall Systems - Series B2500

A commercial aluminum curtain wall system is a non-load-bearing exterior glass wall system that supports glass or panels within an aluminum framing grid and transfers wind load, dead load, water-management, and movement conditions back to the building structure. Boyd Aluminum manufactures the Series B2500 curtain wall system for commercial glass curtain wall projects that require 2.5" sightlines, 6", 7", or 10" system depths, shear block construction, concealed fasteners, field-glazed inside and outside glazing paths, and two-sided structural silicone glazing options.

Use this page to review B2500 curtain wall system details, curtain wall types, inside glazed and outside glazed configurations, two-sided SSG details, system depths, performance references, accessory coordination, and the information Boyd needs to help architects, contractors, glaziers, owners, estimators, and specifiers evaluate the right curtain wall path for medical facilities, schools, office buildings, commercial renovations, and other commercial building-envelope projects.

Curtain Wall System Details: Sightline, Depths, Glazing, and Performance References

The table below summarizes the currently published B2500 curtain wall system details used to compare field-glazed inside and outside configurations, two-sided structural glazing, system depths, sightlines, thermal barrier language, construction method, and performance references. Final requirements should be matched to current product documentation, drawings, specifications, installation conditions, and project engineering review.

Curtain Wall Configurations: Inside Glazed, Outside Glazed, and Two-Sided SSG

B2500 curtain wall configurations support different field-glazed access paths, captured (pressure-plate) glazing or cap-style appearance requirements, two-sided structural silicone glazing, system depth, corner, entrance, window, vent, and finish coordination needs. Boyd can help project teams with early design-assist coordination to match the correct curtain wall type to the architectural design, glass specification, opening condition, structural requirements, and installation sequence.

Curtain Wall vs Storefront and Window Wall Conditions

Storefront and curtain wall are different commercial aluminum framing systems. A storefront system is typically set into and anchored within a low-rise or ground-level opening, while a curtain wall hangs from or anchors back to the building structure and is reviewed for larger glazed elevations, multi-story conditions, structural movement, and water-management demands.

Window wall is a separate slab-to-slab or floor-line condition used on some mid-rise and high-rise buildings. If project documents use window wall, ribbon-window-style, or curtain-wall-style language, send elevations and sections for review so Boyd can determine whether B2500 curtain wall, storefront framing, architectural windows, or another Boyd system should be reviewed.

When to Use the B2500 Curtain Wall System

The Series B2500 is a commercial aluminum curtain wall option for contemporary architectural designs that need a coordinated glass wall system, field-glazed inside or outside glazing paths, two-sided structural glazing options, thermal barrier protection, and compatible curtain wall details. It is commonly reviewed for medical facilities, schools, office buildings, commercial applications, and other building-envelope projects where the curtain wall system must coordinate with glass, entrances, vents, finishes, and structural requirements.

• Use B2500 outside glazed configurations when exterior-side field glazing access and the selected outside glazed details fit the project condition.

• Use B2500 inside glazed configurations when interior-side field glazing access better fits the jobsite, design, or installation sequence.

• Use B2500 SSG configurations when two-sided structural silicone glazing is part of the architectural intent and the selected details support the condition.

• Use 6", 7", or 10" depths based on structural review, mullion depth requirements, glass loads, wind-load and dead-load conditions, and the project engineer's requirements.

• Use door and window adaptors when storefront entrances, architectural windows, or vented products need to be integrated into the curtain wall design.

• Use 90° corner mullions when the curtain wall needs to turn outside corners while maintaining a coordinated system detail.

Common Curtain Wall Coordination Issues

Curtain wall system selection depends on more than the series name. Review these B2500 curtain wall details before finalizing the bid scope, specification path, shop drawings, or submittal package.

• Glazing access and appearance: Confirm whether the project requires inside field glazing, outside field glazing, two-sided structural silicone glazing, captured curtain wall terminology, or a mix of conditions.

• System depth: Coordinate 6", 7", or 10" depth selection with span, structural review, glass weight, wind-load and dead-load requirements, and surrounding construction.

• Water management: Curtain wall systems manage incidental water through glazing pockets, weep paths, gaskets, and perimeter conditions. Coordinate sill conditions, transitions, sealant interfaces, and installation details early.

• Glass and gaskets: Confirm glass makeup, glazing thickness, EPDM gasket requirements, glazing method, structural silicone glazing where applicable, and any 1/4" glazing adaptor needs.

• Entrances and integrated vents: Coordinate door adaptors, window adaptors, storefront entrance doors, SV100 zero sightline vent options where compatible, and adjacent storefront or window systems.

• Corners and transitions: Confirm 90° corner mullions, inside and outside corners, perimeter anchors, floor-line conditions, adjacent substrates, receptors, snap trim, panning, and sealant interfaces.

• Performance documentation: Match air, water, structural, AAMA, wind-load, dead-load, thermal, and Division 08 specification requirements to the selected B2500 configuration and current documentation.

• Finish coordination: Confirm anodized, painted, Kynar®, powder coat, or project-specific finish requirements early so exposed components and accessories align with the architectural intent.

Commercial Curtain Wall Questions

When should a project use curtain wall instead of storefront?

Storefront is usually reviewed for ground-level or low-rise openings set within a surrounding condition. Curtain wall is reviewed when the glazed area is larger, spans multiple stories, crosses floor lines, or needs curtain wall depths, structural review, water management, and movement coordination. For adjacent lower-level entrances and wall conditions, review Boyd's commercial storefront systems and storefront doors.

What is the difference between captured pressure-plate curtain wall and structural silicone glazing?

Captured (pressure-plate) curtain wall glazing generally refers to glass retained by exterior caps, pressure plates, or similar framing components. Structural silicone glazing uses structural silicone to help retain glass on selected edges instead of relying only on exposed exterior aluminum caps. The Series B2500 includes two-sided structural glazing documentation where the selected details support a two-sided SSG condition; final use should be reviewed against current B2500 details, glass makeup, structural silicone requirements, and project specifications.

What is the difference between stick-built and unitized curtain wall?

Stick-built curtain wall is assembled piece by piece in the field, while unitized curtain wall is typically fabricated as larger factory-assembled panels that are installed as units on the building. Stick-built systems are commonly reviewed for commercial projects where field glazing, project-specific dimensions, and jobsite coordination are important. Boyd Aluminum's Series B2500 is a field-glazed curtain wall system with shear block construction and concealed fasteners.

How does a curtain wall manage water?

Curtain wall systems generally do not rely on a single exterior seal. They are designed to capture incidental water that gets past the outer glazing line and drain it through internal glazing pockets and weep paths back to the exterior. Water management depends on the glazing method, gaskets, perimeter conditions, and installation details. For the Series B2500, confirm the selected inside glazed, outside glazed, or two-sided structural glazing details against current Boyd documentation, project specifications, glass makeup, EPDM gasket details, and performance requirements.
