Curtain Wall vs Storefront: A Complete Comparison Guide

For commercial projects, the use of aluminium and glass is a feasible option as they can give an impression of professionalism and elegance. The architect recommends several schemes including: storefronts and facades.

Although the two have very similar appearances, it is crucial to understand their differences as well, as the budget, installation space and style may vary. Next, we will elaborate on the differences between them.

The properties and structures of each of these two types of products are very similar, as they are both a combination of aluminium and glass.

However, the differences between the various projects are quite significant. Let's take a look at what they are:

What is storefront glazing system？

In short: "The large glass facade in the building".It is usually installed inside the openings of single-story or low-rise buildings, and is directly supported by the main structure of the building on all sides.

Storefront glazing system provide lighting, display items, and protect from wind and rain, but it does not bear the main structural weight of the floor or roof.

In addition to the standard length of the Storefront, PRANCE can utilize our in-house aluminum extrusion capabilities to customize the length to meet the specific requirements of each project.

Main Components

• Aluminum alloy frame: Relatively lightweight structure, used for fixing the glass, including window and door tracks.

• Glass panel: Commonly uses tempered glass, insulating glass or laminated glass, emphasizing high transparency and display effect.

• Sealing and drainage: Achieves basic airtightness through EPDM rubber strips and weather-resistant silicone sealant. There are drainage holes at the bottom to discharge the trace amount of rainwater that seeps in.

Applicable scenarios

• Independent shops and retail stores along the street

• First floors of restaurants, cafes and hotels

• Low-rise office buildings, clinics, car showrooms

What is curtain wall system？

Curtain wall system is an exterior wall system that is hung on the exterior side of the building's main structure.

It only bears its own weight as well as wind pressure and seismic forces. These forces are transferred to the building's columns or floor slabs, and it does not bear the structural weight of the building itself.

We offer single-layer tempered glass with thicknesses of 8mm, 10mm, 12mm, 15mm or other custom thicknesses, as well as insulated tempered glass with features of sound insulation, heat insulation, anti-freezing, moisture resistance and wind resistance.

Main Components

• Frame System: Usually consists of aluminum columns and beams.

• Panel Material: The most common type is hollow glass, but it can also be aluminum panels, stone, ceramic panels or composite sheets.

• Anchor Connection Components: Metal connection elements that fix the curtain wall frame to the building's structural floor.

• Sealing and Drainage System: Includes weatherproof silicone sealant, EPDM strips, equal pressure chambers and drainage holes, responsible for waterproofing, airtightness and drainage.

Why are curtain walls commonly used in high-rise buildings?

The high-rise facades require more precise and sturdy glass. The constructed framework needs to undergo rigorous testing.

At PRANCE, we have over 20 years of experience in manufacturing facades, and have become a reliable partner for many developers.

• Natural light and aesthetics：Provides abundant natural light indoors and gives the exterior a modern, transparent appearance.

• Reduced building weight：Much lighter than traditional brick or concrete exterior walls, helping reduce the load on the building foundation.

• Strong performance：When combined with insulated glass, Low-E glass, and thermal-break aluminum profiles, it can provide good insulation, heat resistance, and sound reduction.

• Wind and rain protection：Uses a pressure-equalized drainage system and sealing design to help maintain water resistance in strong wind and rain conditions.

Key Differences: Storefront and Curtain wall 

In simple terms: storefront is a practical choice for low-rise shop or office openings, while curtain wall is designed for larger and taller building facades.

Cost Comparison ：Curtain Wall vs Storefront

Curtain Wall: A High-Performance Applications

• Total cost: Approximately $40 - $100+ per square foot.
• Reasons for high cost: The profiles are thick and need to be customized. The design requires complex wind-resistant and earthquake-resistant engineering calculations. The construction relies on cranes, elevated work platforms, and professional construction teams.

Storefront: A Cost-Effective Choice

• Total cost: Approximately $15 - $30 per square foot.
• Core advantages: Thin material, standardized design, no need for high-altitude operations or large equipment, and extremely low installation and subsequent maintenance costs.

Curtain Wall is typically used in large-scale buildings, in terms of scale and resources. The financial resources required are more than those of Storefront.

Which Glazing System Fits Your Project?

Choose Storefront When:

• Small commercial space
• Ground floor applications
• Budget is priority
• Simple installation required

Choose Curtain Wall When:

• Multi-story buildings
• Large glass facade required
• Premium appearance matters
• High weather performance needed

Conclusion

Choosing between curtain wall and storefront is not only about glass and aluminum. It is about selecting a system that matches your project's performance, budget, and design goals. 

For developers looking for modern prefab buildings, PRANCE provides customized solutions combining aluminum structures, safety glass, and insulation systems to meet different application needs.

FAQS

1. What is the difference between storefront and curtain wall?

Storefront is mainly used for low-rise buildings, shops, and entrances. Curtain wall is designed for larger buildings and provides better wind, weather, and insulation performance.

2. Which one is more affordable, storefront or curtain wall?

Storefront usually has a lower cost, while curtain wall requires a higher investment but offers better performance and appearance.

3. Can you customize glass and aluminum systems?

Yes. We can customize aluminum frames, glass types, sizes, and designs based on different project requirements.

4. Which system is better for my project?

It depends on your building type, budget, location, and design goals. Storefront suits simple commercial spaces, while curtain wall suits large and high-end projects.

5. Do you provide installation support?

Yes. We provides technical guidance, installation drawings, and project support to help ensure smooth installation.
