Types of Storefront Glass Systems

The selection of appropriate storefront glazing systems depends on multiple factors including building height, structural requirements, thermal performance targets, security needs, and aesthetic preferences. New Jersey's diverse commercial building stock accommodates various system types, each offering distinct advantages for specific applications.

Aluminum Storefront Systems (Most Common)

Aluminum storefront systems represent the most widely used commercial glazing solution in New Jersey, offering an optimal balance of performance, cost effectiveness, and installation flexibility. These systems utilize extruded aluminum framing members with insulated glass units, providing reliable weather protection and thermal performance suitable for low-rise commercial applications.

Modern aluminum storefront systems are available in both non-thermal and thermally broken configurations. Non-thermal systems provide basic weather protection and structural support at the lowest initial cost, making them suitable for applications where energy performance is not a primary concern. However, New Jersey's climate zones and energy codes increasingly favor thermally broken systems that incorporate polyamide thermal breaks to eliminate conductive heat transfer through the aluminum framing.

The versatility of aluminum storefront systems makes them ideal for retail establishments, restaurants, professional offices, and multi-tenant commercial buildings. Standard systems accommodate glass thicknesses from 1/4 inch to 1 inch, with insulating glass units providing superior thermal and acoustic performance compared to single-pane installations. Frame depths typically range from 4 inches to 6 inches, with deeper sections providing enhanced structural capacity for larger glazed areas.

Installation flexibility represents a key advantage of aluminum storefront systems. These systems can be field-glazed for maximum customization or factory-glazed for improved quality control and faster installation. Screw-spline assembly methods facilitate field modifications and future maintenance, while structural glazing options eliminate visible exterior caps for clean, contemporary appearances.

Best Applications: Retail stores, restaurants, professional offices, multi-tenant buildings, ground-floor commercial spaces in mixed-use developments.

Advantages: Cost-effective installation, wide range of finish options, accommodates doors and hardware easily, proven long-term performance, extensive contractor familiarity.

Considerations: Thermal performance depends on frame selection and glazing specification. Thermally broken frames and Low-E glass recommended for optimal comfort and energy efficiency in New Jersey's climate zones.

Curtain Wall Systems

Curtain wall systems provide engineered glazing solutions for multi-story commercial buildings, offering superior structural performance, water management, and thermal control compared to conventional storefront systems. These systems are designed to accommodate building movement, wind loads, and seismic forces while maintaining weather-tight performance over extended service lives.

The fundamental distinction between curtain wall and storefront systems lies in structural design and performance capabilities. Curtain wall systems are engineered to span multiple floors and accommodate significant structural loads, while storefront systems are typically limited to single-story applications or low-rise buildings with minimal structural requirements.

Modern curtain wall systems utilize pressure-equalized design principles to manage water infiltration and air leakage. Dual-seal glazing systems with structural and weather seals provide redundant protection against moisture intrusion, while integrated drainage systems channel any water that penetrates the outer seal safely to the exterior. This sophisticated water management capability makes curtain wall systems particularly suitable for high-rise applications where wind-driven rain presents significant challenges.

Thermal performance in curtain wall systems typically exceeds that of conventional storefront systems due to advanced thermal break technology and high-performance glazing options. Structural glazing techniques eliminate thermal bridging at glazing interfaces, while thermally broken mullions and transoms minimize conductive heat transfer through the framing system.

Best Applications: Multi-level façades, atriums, showrooms, high-rise office buildings, institutional facilities requiring superior performance.

Advantages: Handles larger glass sizes, superior water and air performance, accommodates building movement, enhanced thermal performance, architectural design flexibility.
