Storefront Glass vs. Curtain Wall: What’s the Right Fit for Your Project?

Storefront Glass vs. Curtain Wall: Key Differences Explained

When planning a commercial building facade, choosing the right glazing system can impact everything from performance and aesthetics to cost and code compliance. Two of the most common systems used in commercial glass construction are storefront glass systems and curtain wall systems—but while they may appear similar on the surface, they serve very different purposes.

At Sheboygan Glass & Glazing, we help architects, contractors, and business owners select the ideal solution for each project. Here’s a clear breakdown of the differences, benefits, and best-use scenarios for each system.

🏢 What Is a Storefront Glass System?

A storefront system is a non-load-bearing glass and aluminum framing system typically used at ground level. It's designed for ease of access and high visibility—ideal for retail spaces, offices, and entrances.

✅ Best for:

• First-floor commercial entrances

• Retail storefronts

• Low-rise office lobbies

Key Characteristics:

• Installed between floor slabs (not spanning multiple floors)

• Glass is typically supported by the frame itself

• Can accommodate doors and windows

• More economical than curtain walls

• Limited thermal performance and weather resistance in taller structures

  
  

🏗️ What Is a Curtain Wall System?

A curtain wall system is a high-performance, non-structural glass facade that spans multiple floors and attaches to the structural frame of a building. Unlike storefronts, curtain walls are engineered to handle greater loads and provide enhanced thermal and moisture protection.

✅ Best for:

• Multi-story office buildings

• Institutional and government buildings

• Commercial buildings with complex facade design

Key Characteristics:

• Anchored to floor slabs; can span entire building elevations

• Designed to withstand wind loads, seismic movement, and thermal expansion

• Includes advanced water drainage and vapor control

• Higher material and installation cost—but better performance in larger structures

Best Used For	Retail, offices, commercial entrances	High-rise buildings, expansive facades

🛠️ Choosing the Right Fit for Your Commercial Building

When deciding between storefront glass vs a curtain wall system, consider the following factors:

• Building Height & Design Intent – Curtain walls are better suited for multi-story or visually dramatic designs.

• Performance Needs – If you need enhanced energy efficiency, air tightness, and long-term weather protection, curtain walls are the superior choice.

• Budget – Storefront systems are cost-effective for smaller-scale, ground-level applications.

• Code Requirements – Ensure whichever system you select meets local building codes and energy performance standards.
