Upvc curtain wall

Types of uPVC curtain wall

A UPVC curtain wall is a non-load-bearing exterior wall system that consists of uPVC framing with infill panels of glass, stone, or other materials. It is designed to be lightweight and cost-effective. It provides a durable, energy-efficient, and low-maintenance alternative to traditional materials.

The types of uPVC curtain walls include the following:

• Stick Curtain Wall System

  This system involves the on-site assembly of the frame. It is composed of vertical mullions and horizontal transoms that form the framework. The framework is then filled with fixed lights of glass or other infill materials. The stick system is flexible and is often used in low to mid-rise buildings.

• Unitized Curtain Wall System

  This system is prefabricated in a factory. Each wall unit includes mullions, transoms, and infill materials. The installation process is quick because the units are already assembled. This system is suitable for high-rise buildings and offers quality control and speed of construction.

• Mixed Material Curtain Wall

  This system combines different materials for the frame and infill panels. For example, the frame can be uPVC, and the infill panels can be stone, metal, or glass. This allows for customization and the optimization of material properties.

• Structural Glazed Curtain Wall

  This system depends primarily on glass. The glass is attached to the uPVC frame using structural silicone. This creates a smooth, continuous glass exterior. This curtain wall is aesthetically pleasing and is often used in modern buildings.

• Pre-cast Concrete Panel System

  In this system, the curtain wall is made of concrete panels that are cast and cured before being installed. The concrete panels are then installed. This system is durable and suitable for low-rise buildings.

• Stone and Metal Panel System

  This system consists of either metal or stone panels fitted into a uPVC frame. It is durable, low maintenance, and regularly used in institutional and commercial buildings.

• Rainscreen Curtain Wall System

  In this system, the outer layer functions as a rainscreen. The outer layer controls water and directs it to the ground. It prevents water from penetrating the inner layers. This system is energy efficient, durable, and commonly used in residential buildings.

How to choose upvc curtain wall

When considering which UPVC curtain wall system to install, several factors must be considered. These include the location of the building, the intended design, and the budget.

The location of the building is important because it will determine the environmental conditions to which the curtain walls will be exposed. For example, buildings in coastal areas will be exposed to saltwater and high winds, while those in urban areas will be exposed to pollution and debris. Understanding these factors can help select a curtain wall material that can withstand the local environment.

The design of the building will also influence the type of curtain walls to be installed. For instance, glass and aluminum systems are more suitable for modern architectural designs, while stone and concrete systems complement traditional designs. Additionally, the structural requirements of the building will affect the type of curtain wall. Heavier materials may be needed for buildings with high wind loads or seismic activity.

Another important consideration is the cost. Curtain walls can be expensive, and it is important to find a balance between quality and price. It is also important to consider the long-term costs associated with each type of curtain wall. Some may be cheaper initially but will require more maintenance or replacement parts over time, which can add up.

Finally, it is important to consider the installation process. Some curtain wall systems are more complicated and require specialized knowledge, which can increase construction time and costs. Others are easier to install and may be more cost-effective.
