A Guide For Business Owners: Glass Storefronts Vs. Curtain Walls

As a business owner, the exterior of your storefront plays a critical role in attracting and retaining customers. When it comes to designing your storefront, one of the most important decisions you'll make is choosing between glass storefronts and curtain walls. While both options can create an inviting and modern appearance, they each have their own unique advantages and disadvantages. In this guide, we'll explore the key differences between curtain walls and glass storefronts and help you determine which option is best suited for your business. 

By considering factors such as aesthetics, functionality, and cost, you'll be able to make an informed decision that meets the specific needs of your business.

The Differences Between Curtain Walls And Glass Storefronts

When speaking with architects and project managers, both forms of commercial glass refer to a structure's facade or exterior. Both of these phrases pertain to the exterior of a structure and are architectural in nature.

Similarly utilitarian are storefronts and curtain walls. They shield the interior of the structure and its inhabitants from severe weather conditions. In addition, they serve to maximize sunlight and provide exterior insulation.

The similarities between the two words cease here, though. Let's explore the differences between these commercial glass varieties.

  • Application

A glass storefront acts as a framework for a business entrance and is neither residential nor load-bearing. It has commercial windows. Storefront windows are typically 10 feet high or less and are attached to the main entry of its commercial glass doors.

Storefronts are typically used by architects for ground-floor constructions. They might even include storefronts for the second or third story when planning a structure. The storefronts are self-contained and do not deplete themselves.

On the other hand, curtain wall systems are not load-bearing at the outside wall and dangle from every floor part like curtains. These walls may climb higher than 25 feet, depending on the building structure's plan. The walls often come from various floors and are front-coated. It also includes a framework that depletes itself.

Curtain walls are therefore taller than storefronts. Storefronts are on the ground floor or in low-rise buildings, whereas they are applicable in high-rise buildings.

  • Performance

Performance is another important factor to consider when selecting between storefronts and curtain walls. Curtain walls typically have better air, water, and structural performance, especially at higher floors. This is due to the use of unitized systems that are fabricated and pre-assembled in a controlled environment, ensuring that performance requirements are met consistently.

Curtain walls also have better thermal performance than storefront glazing, thanks to the use of a thermal break that separates the pressure plate from the back members. This helps to reduce heat transfer and improve energy efficiency.

However, storefronts have their own advantages, such as their ability to showcase merchandise and provide a clear view of the interior space. They are also typically more economical and easier to install than curtain walls.

Ultimately, the selection between storefronts and curtain walls will depend on the specific needs and requirements of the building and its occupants. It's important to consider factors such as building type, functionality, structural system, glazing, and cost, as well as performance, to ensure that the chosen system meets the desired performance and aesthetic requirements.

  • Water Management

Water management is another important difference between curtain walls and storefronts. Curtain walls are typically designed with individual weep holes for each glass panel to allow for the drainage of water that penetrates the system. This ensures that any water that enters the system is drained out effectively without causing any damage.

On the other hand, storefronts typically have a single weeping system that directs any water entering the system towards the vertical mullion of the sill. This can lead to the system becoming overloaded when exposed to excessive weather elements, such as heavy rain or wind-driven rain. As a result, storefronts are typically limited in height and are not recommended for use on higher floors.

To ensure effective water management in storefront systems, it's important to locate them below the fourth floor where exposure to weather elements is minimal. This can help to prevent any disruptions in the functionality of the storefront windows and ensure that they provide optimal protection and sunlight for the commercial space.

Overall, understanding the water management system of both curtain walls and storefronts is crucial in selecting the appropriate system for a building based on its location and exposure to weather elements.

  • Cost

Cost is an important factor to consider when selecting between storefronts and curtain walls. Typically, storefront systems are less expensive than curtain walls due to the use of different materials and products preferred for entrances and elevations on the first and second floors. These materials may include aluminum framing and glass panels with lower insulation values.

In contrast, curtain walls tend to be more expensive in both material and labor costs. However, they offer higher flexibility in terms of design and performance, making them an attractive option for architects and designers. The cost of both storefronts and curtain walls can also be affected by the type of glass used, the type of aluminum framing or other materials, as well as other options such as thermal break methods and finishing choices.

Ultimately, the cost of a storefront or curtain wall system will depend on various factors such as the size of the building, the level of customization required, the location, and the labor market. It's important to consider these factors carefully and weigh the cost against the desired performance, design, and functionality to select the appropriate system for the building.

  • Durability and Longevity

Durability and longevity are important factors to consider when selecting between storefronts and curtain walls. Curtain walls typically offer better durability and longevity than storefront systems.

Curtain walls are designed to withstand harsh weather conditions, such as wind, rain, and extreme temperatures, without compromising their performance or structural integrity. They are also less susceptible to damage from debris or other impacts.

In contrast, storefronts may be more vulnerable to weather conditions and may require more frequent maintenance and repairs to maintain their functionality and appearance. This is especially true for storefronts installed on higher floors where they are more exposed to weather elements.

Overall, curtain walls are generally considered to be a more durable and long-lasting option compared to storefront systems. However, the actual lifespan of the system will depend on various factors such as the quality of materials used, the installation process, and the maintenance and upkeep of the system over time.

How To Choose The Right Storefront Windows For You

Choosing the right storefront windows for your business is an important decision as it can impact the aesthetics and functionality of your space. 

Here are some key factors to consider when selecting storefront windows:

  1. Purpose: Think about the purpose of the storefront windows. Are they meant to showcase your products, attract customers, or provide natural light? Understanding the purpose will help you determine the type of windows that will best suit your needs.

  2. Style: Consider the architectural style of your building and the image you want to portray to customers. The style of the windows should complement the overall design of the building and align with your brand image.

  3. Material: Storefront windows can be made from a variety of materials, including aluminum, wood, vinyl, and fiberglass. Each material has its own benefits and drawbacks, so consider factors such as durability, energy efficiency, and cost when choosing the material.

  4. Glass type: The type of glass used in storefront windows can impact energy efficiency, safety, and security. Options include single-pane, double-pane, and tempered glass. Consider the climate and weather conditions in your area when choosing the glass type.

  5. Size: The size of the storefront windows should be appropriate for the size of your business and the surrounding environment. Larger windows can provide more natural light and create a more open feel, but they may also be more expensive and less secure.

  6. Cost: The cost of storefront windows can vary depending on the material, glass type, and size. Set a budget and consider the long-term cost benefits, such as energy efficiency and durability, when selecting the windows.

By considering these factors, you can select storefront windows that not only look great but also meet your functional needs and budget.
