Curtain walling has been around for many decades but the modern avatar was presented by the industry some years ago. Ever since then, the system has been used in many commercial buildings due to the umpteen advantages it offers. Curtain walling is the ideal way to protect your commercial building from the vagaries of nature. If you are not aware of the curtain wall system, it is time to get familiar with it.
Types of curtain walling systems-
Stick built systems: These are built by assembling different components at the site of installation. The components are assembled piece by piece.
Unitized or modular systems: Under this system, the units are first assembled at the factory site and then transported to the installation site.
Application in buildings
The kind of building the systems will be used for depends on three factors –
- Height of the building : Stick -built systems are apt for low rise buildings. It is because the exterior access is convenient in such cases. Unitized systems are best for the high buildings as interior support is required for the installation.
- The shape of the building: Stick-built systems are appropriate for buildings with flat surfaces. Unitized systems are appropriate for buildings with slope.
- Location of the building :Unitized or modular systems will be ideal if the building is located in an earthquake-prone area. These systems withstand structural movement in a better way.
- Better quality: which system offers it? : Unitized systems have an edge over the Stick-built systems as far as quality is concerned. The answer to this lies in the way the system is manufactured. The systems built under the controlled atmosphere of the factory are better in quality.
Which system requires more efforts?
If you consider from the labor point of view, the unitized systems require less labor while the Stick-built systems need sufficient labor supply as the units are manufactured on the site.
From the aspect of transportation, the Stick-built systems scores over the unitized system. Small units can be transported from the factory to the installation site. Under the unitized system, it becomes tedious to transport the large prefabricated units to the installation site, thereby incurring higher transportation cost.
The time taken in the Unitized system is less but the time taken in Stick-built systems is more. Stick built systems call for the use of cranes and scaffolding equipment but Unitized systems don’t require them. They can be installed by using mini cranes and hoists.
Both the systems have their pros and cons and should be installed according to your needs.
