Sandwich panels – the ins and outs and interesting facts
Sandwich panels are a type of structural panel that is used in many different applications. Most often, sandwich panels are used as exterior cladding for buildings. They are also used for the construction of partitions, prefabricated buildings and structural elements. In this article we will take a closer look at sandwich panels and their many applications.
A sandwich panel is a structural panel that consists of three layers: the outer sheathing, the inner sheathing and the core. The core can be made of various materials, but the most commonly used cores in sandwich panels are polyurethane (PUR) and polyisocyanurate (PIR). Sandwich panels are made by fusing the layers to the core using heat and pressure.
What are the panels made of?
The outer shell is usually made of sheet metal, such as aluminum or steel. The inner sheathing can be made of sheet metal or another material, such as gypsum board. The following table lists some of the most popular types of sandwich panels based on their outer and inner shells:
Why should you choose panels?
The main advantage of using sandwich panels is that they are lightweight but still very durable. This makes them perfect for a variety of applications, such as exterior cladding, partition walls and prefabricated buildings. Sandwich panels also have good thermal insulation properties due to their cores. This makes them ideal for use in energy-efficient building projects.
Common applications for sandwich panels
As we mentioned earlier, one of the most common applications of sandwich panels is the external cladding of buildings. They are also widely used in the construction of partitions and prefabricated buildings. In addition to these use cases, sandwich panels can also be used for structural elements such as beams and columns. Some other common applications for sandwich panels include:
• Wall coverings
Choose the right material for construction
As you can see, there are many different uses for sandwich panels in construction. Due to their strength, durability and thermal insulation properties, sandwich panels are an increasingly popular choice for a wide range of applications. If you are planning a construction project that requires the use of sandwich panels, be sure to consult a professional to ensure that it is the best option for your needs.
