In today’s buildings, curtain wall systems are integral to the function and appearance of the exterior skin. The curtain wall has retained its popularity amongst architects as an essential way of producing energy-efficient, durable, and visually striking facades in commercial towers, hotels, shopping malls, office buildings, and more.
With the increasing global demand for sustainable building, contemporary curtain wall systems are progressively being engineered to enhance thermal insulation, weatherproofing, and building performance over time.
What Is a Curtain Wall System?
The curtain wall is a lightweight, non-structural exterior facade system consisting of glass, aluminum frames, and various sealing materials. Curtain walls are not load-bearing, unlike traditional walls, which means they do not support a building's principal structural load. What Is a Curtain Wall?But they are fixed to the building structure and act as cladding while keeping the outside elements away and leaving the inside environment hanging.
Contemporary curtain wall systems are popular for high-rise buildings in particular owing to their light weight, durability and high level of customization.
Main Functions of a Curtain Wall
Weather Protection
Protection from the elements – One of the most important roles of a curtain wall is to keep out the wind, rain, humidity and temperature fluctuations. Modern sealing systems and waterproof constructions prevent water penetration and air leakage assuring durability of the building.
Thermal Insulation and Energy Conservation
Economical curtain wall systems generally incorporate features such as double-glazing, Low-E glass and thermal break aluminium profiles to insulate against heat loss. These solutions contribute to control indoor temperatures and decrease the energy required for heating and cooling.
With the advancement of worldwide energy standards, demand for high performance facade systems is on the rise in green building projects.
Sound Reduction
Curtain wall systems are known to improve indoor air quality, but they also eliminate the noise, making it a quiet place to work in. Insulated glass units can significantly reduce sound transmission, which makes them great for office buildings, hotels, airports and even city commercial projects.
Key Components of Curtain Wall Systems
Glass Panels
Glass is one of the most visible elements of a curtain wall system. Depending on project requirements, tempered glass, laminated glass, or insulated glass units may be used to achieve different safety, thermal, and acoustic performance standards.
Aluminum Framing Systems
Aluminum frames provide structural support while maintaining a lightweight facade design. Aluminum is highly resistant to corrosion and allows flexible architectural designs for modern buildings.
Sealing and Waterproof Systems
The use of quality silicone sealants, gaskets and drains, along with the prudent application of rain screen principles enables the glazing system to remain airtight and watertight through all types of weather.
The Importance of Proper Curtain wall Design
A curtain wall system engineered by a professional can bring substantial benefits to a building’s longevity, security and energy efficiency. "It’s designed to take into account structural movement, wind loads and extreme weather."
Nowadays most developers/architects are opting for unitized curtain wall systems as it allows for quicker installation, superior quality control and greater construction efficiency in massive projects.
