A curtain wall is a non-structural facade system that is suspended from the building's structure. It is typically made of glass, metal, or other material that is lightweight and aesthetically appealing. The curtain wall system is installed to create a barrier between the interior and exterior environments, while also providing insulation and allowing natural light to enter the building.The curtain wall is designed to withstand various weather conditions, including wind, snow, and rain, while also being able to support the weight of the building's roof. The system is composed of several components, including glass panels, mullions, spandrels, and thermal breaks. The glass panels used in a curtain wall system can be of different types, including tempered, laminated, insulated, or even fire-resistant glass.The benefits of using a curtain wall system include increased natural light, energy efficiency, and aesthetic appeal. Curtain walls also provide users with excellent thermal and acoustic insulation properties. They are ideal for high-rise commercial buildings, shopping malls, and other large structures.Unitized curtain wall system is a type of curtain wall installation that features pre-fabricated structural units known as modules or panels. These units are assembled off-site and transported to the building's site for installation. The unitized curtain wall system is preferred today, primarily due to its labour-saving nature and faster installation time.The unitized curtain wall system comes with several advantages, including high-quality production standards, repetition of construction details, ease of installation, and better weatherproofing. Other advantages include improved safety on site, cost-effectiveness, and improved site cleanliness. Unitized systems are also less prone to waste production, and their installation time is six times faster compared to traditional stick-built systems.The unitized curtain wall is assembled in a factory setting, where quality control is a priority. Each panel is checked for accuracy, and defects are rectified before installation. The panels are explicit and fit perfectly together, reducing on-site waste.The unit curtain wall system is installed as complete units, with each panel being attached to the adjacent panel through bolts and other fasteners. The fasteners used are designed to provide a high level of strength and stability, giving the entire curtain wall system an added level of security. Unitized curtain wall systems are an excellent choice for buildings in harsh weather conditions, where safety and durability are paramount.In summary, the unitized curtain wall system provides building designers with a faster, more cost-effective, and safer method of building installation, while also providing a high degree of aesthetic appeal. This system is an ideal solution for commercial buildings, shopping centers, and other large structures that require a high level of safety, durability, and environmental efficiency.In conclusion, the curtain wall system is an essential element in modern architecture. The unitized curtain wall is a relatively new innovation that has gained popularity in contemporary architecture due to its several advantages over the traditional stick-built systems. Some of these advantages include better quality control, faster installation time, reduced on-site waste, improved site cleanliness, and cost-effectiveness. The unitized curtain wall system maintains the principles of a curtain wall while also providing faster, safer, and more cost-effective installation.

Curtain walls are one of the most popular and widely used building systems in modern architecture. These structures are designed to provide a visually appealing exterior while also offering a range of functional benefits. Curtain walls are constructed using a variety of materials and techniques and can be customized to suit specific building needs. In this blog, we will explore the different types of curtain walls, their construction details, testing, and prevention against various factors.Types of Curtain WallsThere are many types of curtain walls, each with its unique characteristics and design features. However, the most commonly used curtain walls are frame curtain walls and unitized curtain walls. Let’s look at both in detail.Frame Curtain WallA frame curtain wall comprises an aluminum frame structure that holds the glass panels in place. The frame is fixed to the building structure using mechanical fasteners, which are later concealed with a snap-on cover. The glass panels are fixed to the frame using silicone sealant.The frame curtain wall offers excellent performance in terms of air and water penetration, structural stability, and thermal insulation. The modular design of the frame system provides easy installation and replacement of components.Unitized Curtain WallUnitized curtain walls are pre-fabricated in a factory and shipped to the construction site in sections. The sections are then installed onto the building structure using cranes or other lifting equipment. The panels are typically made from glass or other lightweight materials, while the frame structure is made from aluminum or steel.Unitized curtain walls offer a higher level of customization since the panels can be designed to fit specific building requirements. This curtain wall type provides high performance in terms of air and water penetration, structural stability, and thermal insulation.Construction DetailsCurtain walls are designed to be lightweight and flexible, making them easy to install and replace. The construction details of the curtain wall play a significant role in its overall performance. Here are some critical details to consider.MaterialsThe materials used in the construction of curtain walls, such as aluminum, steel, glass, and sealants, must be durable and weather-resistant. The materials should also be able to withstand the forces imposed by wind, water, and thermal expansion and contraction.SealsThe sealing system used in a curtain wall is crucial to its performance. The sealant must be flexible enough to accommodate movements in the building structure without breaking or cracking. It must also be weather-resistant to prevent water and air infiltration.TestingCurtain walls must undergo rigorous testing to ensure their performance and safety. The tests simulate extreme weather conditions, such as high winds, heavy rain, and temperature changes, to determine how well the curtain wall can withstand such conditions.Prevention Against Various FactorsCurtain walls are vulnerable to various factors that can impact their performance and longevity. Some of these factors include:Water infiltrationWater infiltration can damage the curtain wall and cause mold and mildew growth. Proper sealing and proper drainage systems can prevent water from entering the curtain wall system.Air infiltrationAir infiltration can cause heat loss, leading to higher energy costs. Proper sealing of the curtain wall system can prevent air infiltration and maintain the temperature inside the building.Structural movementStructural movement in the building can cause the curtain wall system to bend or warp, leading to damage. A flexible sealing system can prevent damage caused by structural movement.ConclusionCurtain walls provide an attractive and functional exterior for modern buildings while also offering a range of benefits, such as energy efficiency and weather resistance. By understanding the different types of curtain walls, construction details, testing, and prevention against various factors, building owners can ensure the longevity and performance of their curtain wall system.
