If you're trying to budget a commercial glazing scope in Florida and you can't get a real number, this guide is for you. We'll break down what glass types actually cost, what system selection does to your budget, why the HVHZ adds a premium, and how to get a precise scope for your project — not a number pulled from thin air.
Why Commercial Glass Pricing Is Hard to Pin Down
The honest answer is that "commercial glass" covers an enormous range of products and systems — from a simple tempered pane in a hollow metal frame to a structural silicone curtainwall with triple-silver Low-E coating on a 30-story tower. Those two things are both "commercial glass," but their costs are an order of magnitude apart.
The number that matters to your budget is the installed cost per square foot — meaning the glass, the framing system, all hardware, shop drawings, fabrication, delivery, labor, and any required engineering or testing documentation. That's the number we're going to focus on here.
These ranges reflect Florida market pricing as of 2026 for competitively bid commercial projects. They are not list prices or catalog figures — they're what you should expect to see in a real subcontractor proposal.
Glass Type Pricing: Cost Per Square Foot
Glass type is only one component of your total installed cost — the framing system usually costs more than the glass itself — but understanding glass pricing helps you make informed decisions when value-engineering a spec.
| Glass Type | Typical Range (Glass Only) | Common Applications |
|---|---|---|
| Tempered (monolithic) | $25–$75/SF | Interior partitions, low-wind-exposure storefronts, sidelites |
| Laminated (annealed or tempered) | $40–$100/SF | Overhead glazing, skylights, safety-critical applications |
| Insulating Glass Unit (IGU) | $50–$150/SF | Energy code compliance, curtainwall, window wall |
| Impact-Rated (laminated IGU) | $60–$180/SF | HVHZ, wind-borne debris regions, coastal Florida |
Note that these are glass-only figures. The framing system — storefront, curtainwall, or window wall — adds substantially to the installed cost. More on that below.
Storefront vs. Curtainwall: Installed System Cost
The single biggest cost driver in a commercial glazing scope is system selection. Storefront, curtainwall, and window wall are not interchangeable — they perform differently, install differently, and cost very differently.
Commercial Storefront: $45–$85 per Square Foot Installed
Storefront is a stick-built aluminum framing system designed for low-rise applications — typically single-story or limited-height, non-structural facades. It's the most common glazing system on retail, medical office, restaurant, and single-story commercial projects.
At $45–$85/SF installed, storefront is the most cost-effective glazing system for applications where it performs appropriately. The low end of that range applies to straightforward, single-story scopes with standard aluminum and clear glass. The high end applies to larger projects with architectural finishes, custom colors, monumental heights, or impact-rated glass requirements.
Curtainwall: $150–$350 per Square Foot Installed
Curtainwall is a non-load-bearing exterior wall system that spans floor-to-floor and is engineered to handle wind loads, thermal movement, and water infiltration at high-rise scale. It's substantially more expensive than storefront for good reason — the engineering, testing, shop drawing complexity, and installation labor are all significantly greater.
The $150–$350/SF range for curtainwall is wide because curtainwall projects vary enormously. A standard 2" x 4" stick-built curtainwall on a mid-rise office building sits near the lower end of that range. A custom unitized system on a trophy project with specialty glass, deep shadow boxes, and complex geometry sits at the high end — or above it.

Window Wall: $80–$150 per Square Foot Installed
Window wall sits between storefront and curtainwall in both cost and performance. It's a system where the glazing assembly spans floor-to-floor but sits in front of the concrete slab rather than bypassing it. It's common in mid-rise multifamily construction — and it's increasingly popular because it performs well at a price point that makes sense for residential-over-podium projects.
The HVHZ Impact Premium: What It Costs to Build in Miami-Dade and Broward
Florida's High Velocity Hurricane Zone (HVHZ) — covering Miami-Dade and Broward counties — requires glazing products to pass the most rigorous wind and impact testing in the country. Every glazing product installed in the HVHZ must carry a Miami-Dade Notice of Acceptance (NOA) documenting that it passed large-missile impact testing and cyclic pressure testing per the applicable test protocols.
What does that mean for cost? Expect to add 15–30% to your glazing budget on an HVHZ project compared to an identical project in a non-HVHZ Florida market. The premium comes from several sources:
Product selection narrows significantly. Not every manufacturer's product line has HVHZ NOAs. You're choosing from a smaller menu of tested, approved products — and those products command a market premium.
Documentation and submittal requirements are more extensive. An HVHZ shop drawing submittal is larger, more detailed, and requires more engineering review than a standard Florida submittal. That adds to subcontractor overhead.
Inspection requirements are stricter. Miami-Dade inspectors are looking specifically for correct NOA products, correct anchor patterns, and correct installation sequences. Failed inspections are expensive. A subcontractor with HVHZ experience prices in the cost of getting it right the first time.
Factors That Move Your Number Up or Down
Within any given system type, a dozen variables affect where your actual number lands in the range. Here are the most significant ones:
Glass Specification
The difference between clear tempered and a high-performance triple-silver Low-E IGU in an impact-rated laminate package is substantial. Energy code compliance, tenant comfort, and architectural intent all drive glass selection — and glass selection directly drives cost. Specifying more performance than your project needs is an easy place to spend unnecessary budget.
Frame Finish and Color
Standard clear anodize or bronze anodize aluminum finishes are priced into every standard storefront and curtainwall product line. Custom colors — especially fluoropolymer (Kynar) painted finishes in non-standard colors — add cost. Architectural bronze or painted finishes can add $8–$20/SF to your system cost depending on the finish and the manufacturer.
Project Scale
Larger projects benefit from economies of scale. A 500 SF storefront scope on a single building is more expensive per square foot than a 5,000 SF scope on the same building type. Mobilization, setup, and shop drawing costs are relatively fixed — they don't scale linearly with square footage.
Access and Logistics
Second-floor and above glazing, swing-stage or man-lift work, tight urban sites, and phased-occupancy projects all add cost. If your project has unusual access requirements, your glazing sub needs to know about them at bid time — not as a change order discussion later.
Lead Times and Schedule Pressure
Commercial glazing lead times from major manufacturers in 2026 run 10–20 weeks for standard products and longer for custom specifications. Projects with aggressive schedules may require premium sourcing, expedited fabrication, or split-shipment logistics — all of which add cost. Plan your glazing procurement timeline early. Our Scope Engine can help you generate a preliminary scope and timeline estimate before you even have final drawings.
How to Get an Accurate Scope for Your Project
The ranges in this guide will get you to a realistic ballpark for budgeting — but they will not give you a precise number for a specific project. The only way to get that number is to put your drawings in front of a qualified glazing subcontractor.
What you should provide: architectural floor plans, elevations, and glazing schedules. What you should expect in return: a line-item scope breakdown by system type, a square footage takeoff, system recommendations, and a base bid with clear alternates. A qualified glazing sub should be able to turn that around within 48 hours of receiving complete drawings.
ACG returns a complete scope — quantities, system recommendations, and pricing — within 48 hours of receiving your plans. We've completed 350+ projects across Florida and installed over 1 million square feet of commercial glass. Use our Scope Engine for an instant preliminary estimate, or send us your drawings directly through our contact page.
You can also browse our project portfolio to see completed projects comparable to yours, with system types and scale noted for each.
Frequently Asked Questions
Is commercial storefront glass more expensive in South Florida?
Yes, generally. Projects in Miami-Dade and Broward counties (the HVHZ) carry a 15–30% premium over comparable projects in Central or Southwest Florida, driven by stricter product approval requirements, NOA documentation, and the narrower selection of HVHZ-certified products. Tampa, Orlando, and the Treasure Coast are typically priced within a tighter range of each other.
Does the price include installation?
The ranges in this guide are installed costs — meaning glass, framing, hardware, shop drawings, fabrication, delivery, and labor. They do not include structural steel, rough openings, or adjacent work like sealants by other trades. Your glazing sub's scope letter should clearly define inclusions and exclusions.
What's the lowest-priced commercial glazing system?
Standard storefront with clear tempered glass in a low-wind-exposure location is the lowest-cost commercial glazing application — typically $45–$60/SF installed. Impact-rated storefront in a coastal market runs $60–$85/SF. Any curtainwall or window wall system will cost more than storefront on an apples-to-apples basis.
