Bentonville Is Building Fast: Storefront vs. Curtain Wall, Explained

Anyone who has driven through Bentonville lately knows the skyline is changing. Between the corporate campus construction, the mixed-use projects filling in around downtown and the Momentary, and the steady growth along the Pinnacle Hills corridor in Rogers, Northwest Arkansas is installing more architectural glass right now than at any point in its history. As local glaziers, we get asked constantly what all that glass actually is. The short answer: most of it is one of two systems, storefront or curtain wall, and the difference matters to anyone who owns, manages, or is planning a commercial building here.

Storefront: The Ground-Floor Workhorse

Storefront systems are the aluminum-framed glass walls you see at street level on retail, restaurants, and office lobbies. The framing is typically a 2 inch by 4.5 inch extruded aluminum system, installed floor by floor and spanning from slab to the structure above, usually limited to one or two stories. Storefront is glazed from the interior or exterior with insulated glass units set into glazing pockets with gaskets, and it relies on the building structure above it for support. It is economical, fast to install, and easy to reglaze when a lite breaks, which is exactly why it dominates ground floors from downtown Springdale to the Fayetteville square.

Curtain Wall: The Skin That Hangs

Curtain wall is a different animal. As the name suggests, it hangs off the face of the building structure like a curtain, anchored floor by floor to the slab edges, and it carries no building load other than its own weight and the wind. Curtain wall mullions are deeper and structurally engineered, the system manages water with pressure-equalized rain screen design rather than simple wet seals, and it can run continuously for many stories. The taller glass buildings rising in Bentonville are curtain wall. It costs more per square foot than storefront, and it earns it in performance: better air and water infiltration numbers, better structural movement accommodation, and better thermal breaks.

Why Owners Should Care About the Difference

• Repairs: reglazing a storefront lite is routine work. Replacing curtain wall glass often involves engineered access and specific glazing sequences. Budget accordingly.
• Energy performance: both systems live or die by their glass. Modern IGUs with low-E coatings, argon fill, and warm-edge spacers dramatically improve U-factor and SHGC, the two numbers that govern winter heat loss and summer solar gain. On a west-facing Arkansas elevation, SHGC is the number to fight over.
• Safety glazing: lites at doors, sidelites, and other hazardous locations must be tempered or laminated safety glass certified to CPSC 16 CFR 1201, regardless of system.
• Maintenance: both systems need sealant joints inspected on a cycle. Perimeter wet seals have a service life, and proactive resealing is far cheaper than chasing leaks through finished interiors.
