Frequently Asked Questions On Aluminum Curtain Wall

What Is Aluminum Curtain Wall?

Aluminum curtain wall is a building facade system made of lightweight aluminum panels. It provides a non-structural exterior cladding that offers a sleek and modern aesthetic. The panels are secured to the building’s structural framework, and the gaps between them are filled with insulation and sealants.

This type of curtain wall system is commonly used in commercial buildings and high-rise structures. It serves multiple purposes such as weatherproofing, thermal insulation, and noise reduction. Aluminum curtain walls are durable, low maintenance, and resistant to corrosion, making them a popular choice for architects and builders.

With their versatility and customizable design options, aluminum curtain walls enhance the visual appeal of the building while also improving energy efficiency.

What Is The Difference Between Aluminum Curtain Wall And Storefront?

Aluminum curtain walls and storefronts are two different types of architectural systems used in buildings. Curtain walls are non-structural, thin aluminum frames that are attached to the exterior of a building. They are designed to support their own weight and the loads imposed on them, such as wind and seismic forces.

Curtain walls are usually made up of glass panels, which provide natural light and views, and are often used in high-rise buildings. Storefronts, on the other hand, are typically found on the ground floor of a building and are designed to showcase products and provide access to retail spaces.

They are made up of larger, more robust aluminum frames that support doors and windows. Storefronts are usually more visually prominent and sturdy compared to curtain walls. In summary, curtain walls are used on upper floors to provide a lightweight and transparent facade, while storefronts are used on the ground floor for retail spaces and have a stronger, more visible appearance.

What Are The Three Types Of Curtain Walls?

There are three types of curtain walls: stick-built, unitized, and panel. Stick-built curtain walls are assembled piece by piece on-site, allowing for customization and flexibility in design. Unitized curtain walls are pre-made and fully assembled in a factory setting, and then transported to the construction site for installation.

This type of curtain wall offers a quicker installation process and minimizes on-site labor. Panel curtain walls are similar to unitized systems, but they consist of larger panels that are assembled off-site and then transported and installed on-site. This type of curtain wall system is often used for high-rise buildings and offers efficient installation and reduced overall costs.

How Much Does A Curtain Wall System Cost?

The cost of a curtain wall system can vary depending on several factors such as the size, complexity, and materials used. On average, the cost ranges from $25 to $150 per square foot. The design and customization options chosen, such as glass type, insulation, and special features, can also impact the overall cost.

Additionally, installation costs, including labor, equipment, and any required modifications to the building structure, should be taken into consideration. It’s crucial to consult with a qualified contractor or supplier to get an accurate estimate for your specific project needs. Remember, the cost may vary, so it’s advisable to compare different quotes and negotiate for the best deal.


The aluminum curtain wall is a versatile and efficient architectural solution that brings numerous benefits to buildings.
