Storefront vs. Curtain Wall: A Plain-English Guide for NWA Business Owners and Builders

Drive through downtown Bentonville, past the new construction around the Walmart home office campus, or along the Pinnacle Hills corridor in Rogers, and you are looking at one of the fastest-growing commercial construction markets in the country. Nearly every one of those buildings involves a decision that owners and even some general contractors find fuzzy: storefront system or curtain wall?

Storefront: Glass Within the Structure

A storefront system is an aluminum-framed glass assembly that infills an opening in the building structure, typically at ground level and usually spanning a single floor. The framing bears on the slab and is captured by the structure above. It is the right answer for retail frontage, restaurant facades, office entries, and most tenant improvement work. Storefront framing is economical, quick to fabricate and install, and integrates entrance doors cleanly. Typical system depth is around 4 to 6 inches, and spans are generally limited to about 10 feet of height.

Curtain Wall: Glass Outside the Structure

A curtain wall hangs on the outside of the building frame like a curtain, anchored back to the floor slabs, and can run continuously across multiple stories. Because it carries its own weight and wind load back to the structure at discrete anchors, it handles taller spans, larger glass, and more demanding performance requirements: better air and water management through pressure-equalized rain screen design, more thermal-break options, and the seamless multi-floor glass aesthetic you see on Class A office buildings. It costs more per square foot and demands more engineering, which is exactly why it belongs on the projects that need it and not on the ones that do not.

The Glass Inside Either System

Frame choice is half the conversation. The IGU spec drives comfort and operating cost:

• Low-E coatings: Essential in Arkansas. A good low-E coating manages solar heat gain in our long cooling season.
• SHGC and U-factor: Solar heat gain coefficient matters more than U-factor for most NWA commercial facades, especially west-facing glass in Rogers and Springdale. We spec both numbers to the orientation.
• Argon fill and warm-edge spacers: Standard on quality units, improving thermal performance and reducing perimeter condensation.
• Safety and security glazing: Entrances and glass near walking surfaces require tempered or laminated glass per CPSC 16 CFR 1201; laminated glass also adds forced-entry resistance retailers increasingly ask for.

What This Market Rewards

With the pace of construction in Benton and Washington counties, glazing lead times can make or break a schedule. Getting the glazing contractor involved during design, not after the shell is up, means shop drawings, engineering, and material orders happen in parallel instead of in a panic.
