Installation of sandwich panels – step by step to a durable structure

What  are sandwich  panels  and  where  are they  used?

Sandwich  panels  are  building  elements consisting  of two  skin  layers  – most often   steel  sheet  and  an insulation   core. The  core  can  be  made  of  polystyrene, mineral   wool  or  polyurethane (PIR). Each of  these  materials  has  slightly  different thermal insulation, acoustic and fire resistance parameters.

The  versatility of  sandwich  panels  makes  them  a perfect  choice  for  both  large industrial  facilities and smaller  private  projects.  They are used in buildings such as:

• Storage facilities and logistics centers;
• Sports and recreational facilities;
• Cold stores and freezer warehouses;
• Shopping malls;
• Office buildings;
• Production buildings;
• Garages;
• Residential buildings.

Preparing  the structure  for the installation of sandwich panels

The first step in the installation process is to properly prepare the structure on which the panels will be installed. What should be remembered at this stage?

Checking the load-bearing structure

The structure  must be stable, dry and free of contaminants. In the case of steel or concrete structures, it is important to carefully  check the vertical  and horizontal planes. Even small deviations  can lead to leaks, damage to the panel locks and adversely affect the aesthetics of the workmanship.

Acting in accordance with the design

You should carefully read the technical documentation and the manufacturer’s instructions. Every detail, such as the direction of assembly or the type of connectors, should be in accordance with the guidelines.

Preparing tools and materials

The following will be needed for the installation of sandwich panels:

• Screwdrivers with depth limiters;
• Sealing tapes;
• Electric shears or circular saws for metal;
• Lifts and scaffolding.

Stages of sandwich panel installation – from plan to implementation

The installation of sandwich panels is a process consisting of several steps. Each of them requires precision and proper preparation.

Transport  and  unloading

Panels delivered  to the  construction site must be properly  stored and transported. For longer elements, transport  belts should be used and point support points should be avoided.

Installation of the first panel

The first sandwich panel is crucial for the entire  structure.  It should be mounted precisely to ensure accurate connection of subsequent  elements.

Sealing and connecting subsequent  panels

Many manufacturers recommend gluing sealing tapes at the  panel joints. Subsequent panels are connected using locks that ensure tightness and stability. It is important that the panels are properly pressed. This prevents the formation of thermal bridges.

Installation of additional elements

After the installation of wall and roof panels, it is time to install window  joinery, doors, gates and masking trims.

Common mistakes during the installation of sandwich panels and how to avoid them

The most common  problems during  the installation phase include:

• Inadequate preparation of the structure. Any deviation  of the structure in the vertical or horizontal plane can lead to leakage and the “wave” effect.
• Incorrect sealing. High-quality sealing tapes should be used.
• Damage to panels during transport. It is worth using appropriate equipment for transport and unloading.

Advantages of sandwich panels in modern construction

The most important benefits of using sandwich panels include:

• Energy efficiency. Thermal insulation reduces heating and cooling costs.
• Acoustic insulation. The insulating core effectively reduces noise.
• Speed of construction. Thanks to the simplicity of installation, construction with sandwich panels can be completed much faster than with traditional technologies.
• Durability. The panels are resistant to weather conditions and mechanical damage.
• Aesthetics. A wide selection of colors and profiles allows for adaptation to various projects.

Installation of sandwich panels. Conclusions

The installation of sandwich panels is an effective way to create durable,  energy-efficient and aesthetic  buildings. This process, however,  requires precision and planning.  With proper preparation and adherence  to the manufacturer’s guidelines, it can proceed  smoothly and efficiently. Sandwich panels are an investment that pays off in the form  of time, money and energy savings.
