Quick answers

What's the difference between a storefront and a curtain wall?

A storefront and a curtain wall can both use glass and aluminum, but they are not the same system. In plain terms: storefront is usually a lower-rise ground-level wall, while curtain wall is a full exterior facade system built to resist wind and weather on taller buildings.

The short answer

A storefront system is commonly used at street level for shops, restaurants, lobbies, and tenant spaces. It usually supports one or two stories and sits between the floor and the structure above.

A curtain wall is a non-structural exterior wall system that hangs from the building structure. It is used more often on larger buildings and higher floors, where wind loads, movement, and waterproofing details matter more.

Both are commercial glazing systems. Both need proper design, measuring, fabrication, and installation by a licensed, insured commercial glazing contractor.

How storefronts are usually used

Storefront systems are often chosen for retail entrances, smaller commercial fronts, and interior or exterior openings at grade. They are designed to look clean, provide visibility, and create a practical entrance.

Storefront framing is commonly aluminum. Glass may be tempered, laminated, or insulated, depending on the project and local code. The exact choice depends on safety needs, energy performance, and the building design.

If you are comparing options for a shop, café, clinic, or office entrance, storefront is often the simpler system. It is still skilled work, though. Heavy glass and commercial code requirements make it a job for a pro.

How curtain walls are different

Curtain wall systems are used when the exterior glass wall needs to perform like a building envelope, not just an entrance front. They are attached to the structure and help manage air, water, and wind resistance.

This system is more common on mid-rise and high-rise buildings. It often includes more complex framing, anchors, thermal breaks, and insulated glass units to improve energy performance.

Because curtain wall is part of the exterior envelope, the details matter a lot. Small mistakes can affect weatherproofing, movement, and long-term performance. That is why curtain wall work is typically scoped and bid by experienced commercial glazing contractors.

Plain-English comparison

Think of storefront as the glass front of a business at the ground level. Think of curtain wall as a larger exterior glass skin for a building.

A storefront is usually simpler and more localized. A curtain wall is usually more engineered and more integrated with the building structure.

If you are not sure which one your project needs, a licensed commercial glazing contractor can review the drawings, opening sizes, floor count, and project goals. We can help you get matched at no cost.

What else can affect the choice

Several project details can push a job toward storefront or curtain wall:

Building height and number of stories
Wind exposure and structural movement
Energy goals, including low-E coatings and insulated glass units
Safety requirements, such as tempered or laminated safety glass
Entry design, accessibility, and door integration
Budget, schedule, and maintenance needs

Costs also vary by jurisdiction, size, and specification. If you want a general sense of pricing ranges, see our costs page.

When to call a commercial glazing contractor

If you are planning a new build, tenant improvement, replacement, or facade upgrade, it helps to talk with a qualified contractor early. That is especially true if the project includes large glass lites, a multi-story facade, or a damaged system that may affect safety or weather protection.

We do not fabricate or install anything ourselves. We are a free service that helps you find and connect with a licensed, insured commercial glass and glazing contractor.

In plain English

Storefront is usually the simpler ground-level commercial glass system, while curtain wall is a more engineered exterior facade for larger buildings.

Common questions

Is a storefront the same as a curtain wall?

No. A storefront is usually a ground-level commercial glazing system, while a curtain wall is a larger exterior wall system often used on taller buildings. They can look similar, but they serve different structural and performance needs.

Can curtain wall be used on a one-story building?

Sometimes, but it depends on the design, budget, and performance requirements. A licensed commercial glazing contractor can help determine whether storefront or curtain wall makes more sense for the project.

What glass types are used in these systems?

Both systems may use tempered, laminated, or insulated glass units, depending on safety and energy needs. Low-E coatings, U-factor, and SHGC may also matter for comfort and code compliance.

Do you install storefronts or curtain walls?

No. Paneworks is not a glazing company. We help you find and connect with licensed commercial glazing contractors at no cost to you.

Paneworks is a free matching service, not a glass, glazing, or construction company and not a licensed contractor, and it does not perform any work or give structural, code, electrical, or legal advice. The information here is general and educational. Commercial glazing involves heavy glass, high work, and building code; it must be designed, permitted where required, and installed by licensed, insured professionals. Always verify a contractor's license, insurance, and references yourself, and confirm the glass spec, framing system, code compliance, schedule, price, and warranty in writing before work starts. Costs vary by system, glass type, square footage, framing, height, and your area; confirm all details directly with a licensed commercial glazing contractor.
