Curtain wall System is generally used in high rise buildings with multiple stories. They are also used in large office blocks. Such buildings require a strong and sturdy but lightweight material. Such material will be instrumental in providing the quality of helping it in staying erect and in place. Aluminum suits the bill with utmost perfection; it proves to be the most ideal metal for such purposes.

Naturally, this has to do with its qualities of being corrosion resistant and durable. It has further qualities of being malleable and versatile. This lends it the quality of having the ability to be molded into various shapes and sizes. It is a boon for the architects as they don’t face a restriction they used to face with the traditional materials.


If you are looking for ventilation and insulation in a single feature, it is often difficult to find it. But with the curtain wall system, it is not a tough objective to achieve. You will be surprised at the Curtain wall System’s ability to keep the heat in and out as and when you need to.

People’s requirements change according to seasons and curtain walls will be perfect for every season. In summers, you can effectively cool the building and keep the cold inside. In winters, the same is true for heating the interiors.

In addition, vents can be installed to ensure that the building has enough ventilation. So it works for you whether you look at it from the financial or the ecological angle.

Curtain wall system comprises one of the elements of facade technology in high rise buildings. Facades involve window wall, cladding elements, and curtain walls which generate the exterior envelope of the building.

The curtain wall systems now possess structural importance equivalent to that gained by other structural elements of the building. As it has a higher exposure to the exterior atmosphere, it has to be properly designed, installed, and maintained keeping in mind the functionality and sustainability.

Types of Curtain Wall System

Many curtain walls today have at least some sort of glass component, allowing users of the build views while creating Opportunities for natural light.

Glass curtain walls come in two main types, stick-built or unitized. Each has its own advantages and disadvantages, as well as its own methods and equipment for installation. Knowing the differences between the two and how to install each is a vital skill for anyone in the construction industry.

Design Consideration

AluFab Metals considers many factors while designing the Curtain wall system which should handle all loads imposed on it as well as keep air and water from penetrating the building envelope.

The loads imposed on the curtain wall are transferred to the building structure through the anchors which attach the mullions to the building.

Dead load
Dead load is defined as the weight of structural elements and the permanent features of the structure. In the case of curtainwalls, this load is made up of the weight of the mullions, anchors, and other structural components of the curtain wall, as well as the weight of the infill material. Additional dead loads imposed on the curtain wall may include sunshades or signage attached to the curtain wall.

Wind load
Wind load is the normal force acting on the building as the result of wind blowing on the building. Wind pressure is resisted by the curtain wall system since it envelops and protects the building.

Seismic load
Seismic loads in the curtain wall system are limited to the inter-story drift induced on the building during an earthquake.

Snow load
Snow loads and live loads are not typically an issue in curtain walls, since curtain walls are designed to be vertical or slightly inclined.

Thermal load
Thermal loads are induced in a curtain wall system because aluminum has a relatively high coefficient of thermal expansion.

Blast load
Accidental explosions and terrorist threats have brought on increased concern for the fragility of a curtain wall system in relation to blast loads.
