Curtain Wall vs Storefront Systems
Commercial buildings throughout the Bay Area rely on glazing systems that do far more than create attractive architecture.
Should a project utilize a curtain wall system?
Or is a traditional storefront system the better solution?
Whether developing office towers in San Francisco, technology campuses in San Jose, biotechnology facilities in South San Francisco, corporate headquarters in Redwood City, or mixed-use developments in Oakland, selecting the right glazing system influences structural performance, energy efficiency, appearance, and long-term operating costs.
Curtain walls define modern skylines.
Storefront systems shape the street-level experience.
Both play an essential role in commercial construction.
✓ Curtain walls support large-scale commercial architecture
✓ Storefront systems create functional street-level entrances
✓ Both improve long-term building performance
✓ Building design ultimately determines the best solution

How Commercial Glazing Systems Have Evolved
Commercial building design has changed dramatically over the past several decades.
50 Years Ago
Most commercial buildings relied on traditional storefront systems and conventional window assemblies.
Many buildings throughout San Francisco, Oakland, Berkeley, San Jose, and older downtown business districts utilized:
- Aluminum storefront framing
- Single-pane glazing
- Basic entrance systems
- Limited thermal performance
Curtain wall systems were generally reserved for larger office towers and institutional buildings.
25 Years Ago
Commercial redevelopment accelerated throughout the Bay Area.
Corporate campuses expanded.
Downtown skylines evolved.
Property owners increasingly focused on:
✓ Modern architectural design
✓ Better energy performance
✓ Larger glass facades
✓ Reduced maintenance costs
Curtain wall systems became increasingly common on mid-rise and high-rise commercial buildings.
10 Years Ago
Commercial real estate became increasingly performance driven.
Ownership groups prioritized:
✓ Sustainability
✓ Workplace quality
✓ Daylighting
✓ Building envelope performance
Today, curtain walls and storefront systems frequently work together within the same commercial development.
Commercial Properties Utilizing Curtain Walls And Storefront Systems
Nearly every commercial development incorporates one or both glazing systems.
Project activity remains common across:
- Downtown San Francisco office towers
- San Jose corporate campuses
- Fremont advanced manufacturing facilities
- Santa Clara technology parks
- Mountain View and Sunnyvale research campuses
- Palo Alto life science properties
- Redwood City and South San Francisco biotechnology facilities
- Walnut Creek and Pleasanton office centers
- Oakland mixed-use redevelopment
- Santa Rosa healthcare campuses
- Napa hospitality properties
- Fairfield logistics facilities
Different buildings create different priorities.
High-rise offices often require curtain walls.
Retail properties depend on storefront systems.
Corporate campuses frequently incorporate both.
Curtain Wall Systems
Curtain walls are non-load-bearing exterior facade systems that attach to a building’s structural frame.
They are commonly used on larger commercial buildings where expansive glass surfaces and high-performance building envelopes are required.
Typical curtain wall applications include:
- Office towers
- Corporate headquarters
- Healthcare campuses
- Research laboratories
- Hotels
- Institutional buildings
Common advantages include:
✓ Expansive daylighting
✓ Modern architectural appearance
✓ High-performance glazing
✓ Superior building envelope integration
Throughout commercial markets like San Francisco, San Jose, Redwood City, Palo Alto, and South San Francisco, curtain wall systems remain a defining feature of modern commercial architecture.

Storefront Systems
Storefront systems are designed primarily for ground-level commercial applications.
They create customer entrances while supporting retail visibility and accessibility.
Typical storefront applications include:
- Retail centers
- Restaurants
- Mixed-use developments
- Medical offices
- Professional office buildings
- Hospitality properties
Common advantages include:
✓ Customer visibility
✓ Flexible entrance design
✓ Cost-effective construction
✓ Easier maintenance
Storefront systems remain especially common throughout Walnut Creek, Pleasanton, Dublin, Livermore, Berkeley, Concord, and neighborhood commercial districts across the Bay Area.
Building Envelope Performance
Both curtain walls and storefront systems contribute to the overall building envelope.
Each serves a different purpose.
Curtain walls protect larger structures.
Storefront systems support customer-facing environments.
Modern ownership groups frequently evaluate:
✓ Thermal performance
✓ Water management
✓ Air infiltration
✓ Structural movement
✓ Long-term durability
Across technology campuses in Santa Clara County, office developments in San Mateo County, and mixed-use projects throughout Alameda County, glazing system selection increasingly aligns with broader building performance objectives.
Commercial Markets Driving Curtain Wall And Storefront Construction
Commercial glazing investment continues throughout nearly every major Bay Area market.
Ongoing activity remains common across:
- San Francisco
- San Jose
- Oakland
- Fremont
- Santa Clara
- Sunnyvale
- Mountain View
- Palo Alto
- Redwood City
- South San Francisco
- San Mateo
- Burlingame
- Foster City
- Menlo Park
- Walnut Creek
- Pleasanton
- Dublin
- Livermore
- Concord
- Berkeley
Many projects combine curtain wall systems on upper floors with storefront systems at street level, creating integrated building envelopes that balance aesthetics, performance, and customer experience.

Regional Commercial Drivers
Three Bay Area counties consistently generate the highest concentration of commercial glazing projects.
Santa Clara County
As the economic center of Silicon Valley, Santa Clara County contains one of the nation’s largest concentrations of corporate headquarters, semiconductor manufacturing, research laboratories, and technology campuses.
Commercial investment remains especially active throughout San Jose, Santa Clara, Sunnyvale, Mountain View, Cupertino, Milpitas, Campbell, Los Gatos, Morgan Hill, and Palo Alto.
Common priorities include:
✓ Corporate campus development
✓ Research facility construction
✓ Curtain wall modernization
✓ Workplace improvements
Alameda County
Alameda County combines technology, logistics, manufacturing, healthcare, higher education, and retail into one of California’s most diverse commercial markets.
Major commercial activity extends across Oakland, Fremont, Berkeley, Pleasanton, Livermore, Dublin, San Leandro, Newark, Alameda, and Hayward.
Common priorities include:
✓ Mixed-use redevelopment
✓ Storefront modernization
✓ Industrial office improvements
✓ Building envelope upgrades
San Mateo County
San Mateo County connects San Francisco with Silicon Valley while supporting one of the nation’s highest concentrations of biotechnology, healthcare, hospitality, and corporate headquarters.
Commercial investment remains active throughout Redwood City, San Mateo, South San Francisco, Burlingame, Foster City, Menlo Park, San Carlos, Belmont, and Millbrae.
Common priorities include:
✓ Corporate headquarters
✓ Laboratory expansion
✓ Hospitality development
✓ High-performance building envelopes
Choosing The Right Commercial Glazing System
Every commercial project presents unique design requirements.
High-rise buildings often benefit from curtain wall systems.
Ground-level commercial spaces typically perform best with storefront systems.
Many modern developments successfully incorporate both.
The best solution depends on building height, structural design, occupancy, architectural goals, energy performance requirements, and long-term ownership strategy.
Across San Francisco, San Jose, Fremont, Walnut Creek, Redwood City, Oakland, Pleasanton, Santa Rosa, Napa, and commercial markets throughout the Bay Area, curtain walls and storefront systems continue defining the next generation of commercial architecture.
That evolution makes the relationship between curtain wall systems and storefront systems one of the most important discussions in commercial glazing, connecting directly to architectural design, building envelope performance, tenant improvements, sustainability, energy efficiency, and long-term commercial property value.
