The Importance and Benefits of a Curtain Wall System for Your Building

Updated: Feb 12

Curtain Wall System

A curtain wall system is a type of wall system that is installed on the exterior of a building structure to help keep the weather out. Here's what you need to know about curtain walls, including how they work, the different types, and the benefits they can offer you.

What are curtain walls and how do they work?

Curtain walls are non-structural wall systems, which means they do not carry the weight of any part of the building, except their own weight. They are typically joined to the structure of the building by a type of stud or screw system.

Any wind or gravity load experienced by the curtain walls is transferred to the structure of the building, usually through the floor line.

Since curtain walls are non-structural, they can be made from more lightweight materials. The typical curtain wall materials are glass with a steel or aluminium frame, although metal panels or thin stone can be used in place of glass.

What are the benefits of curtain wall systems?

Curtain wall systems are a popular choice for modern commercial buildings because they offer a wide range of benefits including:

  • Keep out the weather. First and foremost, curtain wall systems offer excellent weather protection. This not only improves the performance of the building but will increase its durability as well.

  • Resist water penetration. Curtain walls are designed to prevent water from penetrating the system and to keep the interior of the building dry.

  • Reduce building sway. Curtain walls are specially designed to disperse stress from sources such as high winds, improving the overall steadiness of the building.

  • Increase energy efficiency. By using glass that is treated and glazed properly, curtain wall systems can reduce the amount of heat lost or gained by a building. Better thermal efficiency can lead to reduced energy consumption in the building.

  • Improve fire resistance. Curtain wall systems can help slow down the spread of fire by acting as a barrier and compartmentalizing a building. The specialized fire-resistant glass will help protect occupants and the building itself.

  • Elevate building appearance. Glass curtain walls can create a classy appearance for both high-rise buildings and low-rise buildings.

  • Superior visuals. The large glass panels of a curtain wall improve visibility and increase natural light, making the interior of the buildings better too.

  • Versatile design options. Curtain wall systems can be designed and manufactured to a wide range of specifications to suit the specific aesthetic and practical needs of a project.

What are the different types of curtain walls?

Curtain walls are usually classified as unitized or stick systems (AKA modular curtain walls). These categories refer to the different manufacturing and installation methods used.

  • Stick Systems

The curtain wall frame (mullions) and vision glass panels of a stick system are installed one piece at a time which allows for adjustments to be made on site.

  • Unitised Systems

For unitized systems, a single unit or several large units are made and assembled in the factory before being sent to the building site where they are installed. This helps save on installation costs and time.

The size of a single unit is typically the distance of one story from floor to floor of the building.

Curtain walls may also be classified into one of the following categories:

  • Face-sealed

  • Water-managed

  • Pressure-equalized

Pressure equalized systems offer the highest level of weather protection as the exterior face of the glass and glazing act as a rain screen. An air barrier inside the system helps equalize the pressure, preventing water from penetrating.

Benefits of RP Technik curtain wall systems

Australia Fire Control offers the RP Technik range of curtain wall systems. These systems offer the highest level of performance and aesthetics, as well as excellent durability in Australian climates.

RP Technik systems can be used in a wide range of applications including when large spans are required and when maximum protection is required, such as bullet and burglar resistance.

The steel frames allow for larger spans because steel has three times the load-bearing capacity compared to aluminium. The glass panels are optimized for visibility, thermal performance, and acoustic comfort.

The range of RP Technik curtain wall systems is designed to maximize the ease and efficiency of installation. They come with a range of connection types including nail fastening systems, set stud technology, and screw-and-plug connections.
