Curtain Wall vs Storefront Systems in Central Florida
Commercial buildings throughout Central Florida use a variety of glazing systems to create attractive, durable, and energy-efficient building exteriors. Two of the most common systems are curtain walls and storefront systems. While they may appear similar from the outside, they serve different structural purposes, support different building types, and are designed for different performance requirements. Understanding the differences helps property owners, architects, developers, facility managers, and general contractors select the right system for each project.
Across Orlando, Winter Park, Lake Mary, Sanford, Altamonte Springs, Kissimmee, Celebration, Oviedo, Apopka, Winter Garden, Ocoee, Clermont, Davenport, Maitland, Longwood, and neighboring commercial markets, both curtain wall and storefront systems play an important role in new construction, tenant improvements, and commercial renovations.
Understanding the Two Systems
Although both systems incorporate aluminum framing and commercial glass, they function differently within the building envelope.
The primary differences involve:
✓ Structural support
✓ Building height
✓ Load distribution
✓ Water management
✓ Installation methods
✓ Thermal performance
✓ Architectural flexibility
Choosing the appropriate system depends on the building’s design and long-term objectives.
What Is a Commercial Storefront System?
Storefront systems are typically installed at ground level or on low-rise commercial buildings.
They commonly include:
- Aluminum storefront framing
- Tempered safety glass
- Insulated glass units
- Commercial entrance doors
- Automatic door systems
- Sidelites
- Transom glass
- Accessible entry systems
Storefront systems are widely used because they provide attractive entrances while remaining cost-effective for many commercial applications.
What Is a Curtain Wall System?
Curtain walls are engineered exterior wall systems that attach to the structural frame of a building.
They are commonly installed on:
• Mid-rise office buildings
• High-rise developments
• Hotels
• Hospitals
• Corporate headquarters
• Educational facilities
• Government buildings
• Mixed-use towers
Because curtain walls span multiple floors, they are designed to resist wind loads, accommodate structural movement, and support large expanses of architectural glass.

When Storefront Systems Are the Best Choice
Many commercial properties benefit from storefront construction.
Storefront systems are commonly selected for:
✓ Retail centers
✓ Restaurants
✓ Professional offices
✓ Medical offices
✓ Banks
✓ Shopping plazas
✓ Service businesses
✓ Small commercial buildings
They provide durable performance while allowing customers easy access and maximum visibility.
When Curtain Walls Offer Greater Value
Larger commercial developments often require more advanced glazing systems.
Curtain walls are frequently recommended when projects involve:
- Multi-story construction
- Large glass façades
- Premium architectural appearance
- Increased daylighting
- High wind performance
- Modern office towers
- Corporate campuses
- Landmark commercial buildings
These systems become an integral part of the building’s exterior envelope.
Performance Differences
While both systems use similar materials, their performance characteristics vary.
Curtain walls generally provide:
✓ Greater structural capacity
✓ Larger uninterrupted glass areas
✓ Higher wind resistance
✓ Improved building movement accommodation
✓ Advanced drainage systems
Storefront systems typically offer:
- Simpler installation
- Lower overall project costs
- Faster construction schedules
- Excellent performance for low-rise buildings
- Straightforward maintenance
- Flexible tenant build-out options
Selecting the appropriate system depends on the building’s intended use rather than appearance alone.
Florida’s Climate Influences System Selection
Central Florida weather creates unique challenges for commercial buildings.
Design teams regularly account for:
- Hurricane-force wind events
- Wind-driven rain
- High humidity
- Intense solar exposure
- Thermal expansion
- Heavy seasonal rainfall
- Moisture management
- Long-term durability
Both curtain wall and storefront systems can be engineered to perform well under Florida building requirements when properly designed and installed.

Buildings That Commonly Use Each System
Typical storefront applications include:
- Retail centers
- Restaurants
- Medical offices
- Strip malls
- Financial institutions
- Automotive dealerships
Curtain walls are more commonly found on:
✓ Corporate office buildings
✓ Hotels
✓ Hospitals
✓ Convention facilities
✓ Educational campuses
✓ Government buildings
✓ Mixed-use developments
✓ Large commercial complexes
Each system is designed around the building’s structural and operational needs.
Planning the Right Glazing System
Every commercial project begins with evaluating the building as a whole.
Key considerations often include:
✓ Building height
✓ Structural design
✓ Budget objectives
✓ Energy efficiency goals
✓ Architectural vision
✓ Occupancy type
✓ Maintenance expectations
✓ Future expansion plans
Working through these factors early helps ensure the selected glazing system supports long-term building performance.

These communities feature everything from neighborhood retail centers and medical offices to corporate campuses, hospitality developments, educational facilities, and large mixed-use projects that utilize both storefront and curtain wall systems.
Selecting the Right Solution for Your Building
Curtain walls and storefront systems each serve an important purpose within commercial construction. Storefront systems provide practical, durable entrances for low-rise buildings and retail environments, while curtain walls support larger architectural designs requiring enhanced structural performance and expansive glass façades. Whether developing a new office building in Lake Mary, modernizing a hotel in Orlando, renovating a retail center in Winter Garden, or constructing a mixed-use project in Kissimmee, selecting the right glazing system helps improve building performance, strengthen the building envelope, enhance energy efficiency, and create commercial properties built for decades of reliable service.
