Step-by-step installation instructions for sandwich panels

he installation of sandwich panels can be divided into several stages.

1. Transportation of the panels to the construction site, and unloading.

For packages up to 6 meters in length

The panels can be unloaded manually or with a forklift. It is recommended to use forklifts with adjustable width forks: the minimum distance between forks should be 2 m with a width of 150 mm.

For packages over 6 meters in length

These packages must be lifted using conveyor belts and spreader bars. The indicated belt spacing for 6 m to 12 m packages is 2-4 m. For packages longer than 12 m, the conveyor belt separation is 3.5-4.5 m.

Avoid point supports when unloading panels. Otherwise, there is a risk of damaging the lower panel sheathing.

2. Quality control of the finished structure

Before installing the panels, it is necessary to check if the structure to which the sandwich panels will be fixed is straight. Even the slightest deviation in the execution can cause leakage at the joints between panels, resulting in the so-called “wave effect” (the panels are not in the same plane).

3. Removal of the protective film

It is best to remove the foil just before transporting the panel to the installation site. It is not recommended to remove the foil after installing the panel.

4. Sealing

Before fixing the panel, apply strips of PES sealing tape. It shall be fastened to the structure where it will be in contact with the interior lining of the sandwich panels.

The use of seals prevents mechanical damage to the coating.

5. Installation of sandwich panels

The safest and most recommended assembly solution is the use of vacuum lifters to transport the panels.

Install the first panel using fasteners that penetrate the full thickness of the panel, up to the building element.

6. Installation of door, window and skylight profiles.

The installation of door and window profiles, i.e. windows, doors, gates, small windows, etc., requires a separate description.

In the case of roof panels, skylights are also included. The entire range of small windows supplied by PanelSandwich.ORG has locks, which facilitate their attachment to the sandwich panels, without the need to purchase and install additional elements to fit them.

All PanelSandwich.ORG sandwich panels can be easily cut on site, using, for example, the usual metalworking tools:

Jig saws

Reciprocating saws


The use of high temperature cutting tools, e.g. angle grinders, is not permitted. This could damage the anti-corrosion coating.

7. Mounting the rear panels

When mounting the rear panels, it is very important to make sure that the panels are pressed down correctly, in order to ensure maximum tightness of the fasteners.

If the fasteners are correctly pressed, PanelSandwich.ORG panels completely eliminate the problem of so-called “thermal bridges”.

Places where panels are joined without any fastening (e.g., a horizontal joint between one panel and another, in a column, or a joint between a wall panel and a ceiling panel), should be additionally sealed, for example with low pressure polyurethane foam or butyl.

8. Masking treatments

The last stage is the installation of masking treatments, e.g., joints, corners, wind suspenders, ridges or skirting.

9. How to fix small elements, e.g. a company logo, lighting elements or a surveillance system.

PanelSandwich.ORG allows the installation of small elements without the need for an additional substructure. However, in such a case, the following recommendations should be followed

The maximum load exerted by the fastened elements is 10 kg/m2.

The fasteners must penetrate the entire panel (the core and both claddings; it is absolutely forbidden to fasten them only to one cladding).

Apply a washer with a minimum diameter of 40 mm on the opposite side of the fastened element (it is necessary to distribute the loads over the largest possible surface).
