Curtain Wall vs. Storefront: What Bentonville's Building Boom Means for Your Glazing Choices

Drive through Bentonville in spring 2026 and the construction is impossible to miss: the blocks around the Walmart home office campus keep filling in, downtown keeps adding mixed-use buildings, and the corridor from Pinnacle Hills in Rogers up through Centerton is sprouting medical, office, and retail shells. Nearly every one of those buildings wraps itself in aluminum-framed glass, and nearly every owner eventually asks us the same question: what is the difference between storefront and curtain wall, and which one is my project?

Storefront: The Ground-Floor Workhorse

A storefront system is a non-load-bearing aluminum framing system designed for ground-level use, typically spanning floor to structure at heights up to about 10 to 12 feet. It installs between slabs, carries its own weight down to the sill, and integrates entrance doors naturally. It is the economical, fast, and completely appropriate choice for:

• Retail and restaurant frontage like the shops on the Bentonville square or in strip centers along Walnut in Rogers.
• Single-story offices, clinics, and branch banks.
• Ground floors of multi-story buildings, even when the floors above use something else.

Modern thermally broken storefront with low-E insulated glass units performs far better than the systems of twenty years ago, and current energy codes effectively require that level of performance in new work.

Curtain Wall: The Building's Skin

A curtain wall hangs off the face of the building structure like a curtain, anchored floor by floor, spanning multiple stories in a continuous plane of glass and aluminum. Because it is outboard of the slab edges, it delivers the uninterrupted glass facades you see on newer offices and hotels. Curtain wall is engineered for higher wind loads and greater movement, drains water in a more sophisticated pressure-equalized way, and costs meaningfully more per square foot than storefront. It is the right system when the design calls for glass spanning past floor lines, for tall lobbies, or for the performance demands of a signature facade.

Where Owners Get in Trouble

• Using storefront too tall: Pushing a storefront system beyond its span limits to save money leads to deflection, air and water leaks, and glass stress. If the opening is taller than the system's rating, you need curtain wall or heavy commercial framing, full stop.
• Ignoring thermal performance: With energy codes tightening again in the 2026 cycle, non-thermal framing and clear monolithic glass are no longer code-viable in most new applications. Budget for thermally broken frames and quality low-E IGUs from day one.
• Forgetting the doors: Entrances take the abuse. Specify medium or wide stile doors for heavy traffic, and continuous hinges where slamming is a way of life.

Existing Buildings: Retrofit Is Booming

Plenty of 1990s and 2000s NWA commercial stock is wearing original non-thermal storefront with failing IGUs. Reglazing with high-performance units, or full frame replacement with thermally broken systems, upgrades comfort, energy costs, and curb appeal without touching the structure. It is some of the highest-return glazing money an owner can spend in 2026.
