In the construction sector, precast, one of the new generation concrete systems, has become the favorite of both companies and users due to the time and low budget it provides. Precast offers different options for exterior cladding. The use of panels can be preferred as precast panel and shell precast.
Both have different advantages in terms of aesthetics and budget. Although they have similarities in terms of construction, they can be distinguished by their differences in the assembly stage. To better analyze the factors causing these differences, it is necessary to understand what panel and shell precast are.
What is Precast Panel?
The precast system is a system that cannot be explained in a single process and includes quite different production, design, and assembly stages. In the part where what precast panel is, one of the two different systems that can be considered for precast exterior cladding, it refers to the process that can be carried out without the need for wall construction and insulation.
Steel anchorage, steel frame, and halfen channel system are used in transferring the panels to the structure. Although precast facade panels are lightweight and sturdy, they add solidity to the structure through this assembly system. Especially in newly built structures, it incurs less expense, can be completed in a short time, and can be used in buildings.
What is Shell Precast?
Precast shell panels are a design that allows very different surfaces. It can be produced in the desired shape and size. In this process, rough construction is carried out, and partitioning is also done on the walls.
Then the prepared shell precast system is mounted on the structure. Different precast applications such as buttress and cornices can also be applied to the region where this process is applied to complete the project. It can also be obtained in desired colors during production. There is a galvanized steel construction carrier on the back of the panels. Thus, it provides convenience in the transportation process to the structures. It provides a natural stone appearance and is compatible with any area it is used in.
What are the Differences Between Panel and Shell Precast?
Precast shell panel can be preferred with or without insulation. For insulation, materials such as mineral wool, cellulose, polyurethane, perlite concrete, and foam concrete can be used. It is much lighter in form. However, it shows high resistance in situations such as earthquakes that create impacts and vibrations. The assembly process is quite short. It can be used in harmony with different facade materials.
Production can also be made according to the desired thickness in shell panels. We can consider precast panel as the lower layer of the job. Shell panels are systems used for the application of systems such as cornices, buttresses, etc., on top of these. Precast panels are made without the need for concrete masonry, as in traditional systems. On the other hand, if the design of shell panels is determined, production can even be carried out before the construction project starts.
