Sandwich panels are a type of modular building material used to cover structures and buildings. These panels are made up of two layers that serve as the outer structure, ensuring form, weather resistance, and rigidity. They have a core that provides thermal and acoustic insulation.
Polyurethane sandwich panel properties
The superb insulation provided by polyurethane sandwich panels is one of its most essential characteristics. The plates’ core provides minimal heat conductivity, resulting in superior insulation. As a result, it is frequently used in building renovations, both on roofs and facades, as well as in the construction of industrial structures.
Sandwich panels are quickly manufactured and installed. They are screwed to the structure for assembly, and depending on the finish, they can be visible or concealed screws. As a result, the construction time is among the shortest when compared to other systems.
The variety of shapes and finishes available on the market is one of the most significant advantages of sandwich panels as a construction element. Depending on the architecture, many types of panels are available. The finishes range from rustic to modern, with imitation wood and imitation tile panels among others.
What is the size of a sandwich panel?
The insulation board is typically 1,000 mm wide, but in some models, it is 1,150 mm wide. The length of the sandwich panel can be adjusted to meet the needs of each project, with the most common dimensions being 3 to 6 metres, but in some cases, a maximum length of up to 16 metres can be achieved. The thicknesses of these panels can vary greatly depending on the final application, with the most common values ranging between 40 and 150-200 mm thick.
What are sandwich panels used for, and what varieties are available?
These insulating features are especially beneficial in industrial buildings with low-temperature processing roofs and facades. They are perfect for remodeling enclosures because of their modest weight. They are also useful in the insulation of cold rooms and warehouses, sports centres and retail malls, and new and refurbished residences.
Facade sandwich panels
Sandwich panels for facades have been enhanced for use in building enclosures in residences, schools, hospitals, industrial parks, and retail malls. Sandwich panels are also available for interior walls that need insulation.
The benefits provided by these façade panels are heavily dependent on the manner of panel connecting. The attaching mechanism is tongue-and-groove, ensuring optimum protection and avoiding heat and humidity dissipation.
Roofing sandwich panels
Sandwich panels for roofs differ from façade panels in that they must withstand large amounts of snow, rain, and other climatic factors.
They are fastened to the structure with self-drilling screws to prevent leakage in the event of rain or humidity, and are frequently combined with sealing joints to expedite installation without sacrificing the insulation layer.
Panels that are refrigerated
Sandwich panels can also be utilized as insulation in cold rooms or freezers. In these cases, the sandwich panel is made thicker than usual in order to withstand negative temperatures.
Special attention must be paid to the joints between the sandwich panels in order to maintain the extreme temperatures required for the preservation of fresh food products.
